more profit from repairing LCD/LED TV. Because of LCD/LED TV has lots of 
the market now. And many of them are starting occur the problem now. If we 
can repair it, so the profit is quite high to earn. 
2) Inside this repair guide, I will NOT or I will seldom to provide the repair case 
about the failure of “Bulged” or “Bad ESR” values of Electrolytic Capacitor/s. 
As a TV repairer it is a very first step to see and measure the PCB boards inside 
the TV. Because it is a very basic things as a repairer need to know or know 
how to measure it. I highly recommend using the Blue ESR tester to testing 
electrolytic capacitor. 
3) You can choose the chapter you’re interesting to read. For example you want 
to know learn the new PSU Self Test Method, you can directly go to that 
chapter and reading it. 
4) Actually all the LCD & LED TV their structure are nearly same. So we can 
learn the LCD/LED TV repairing information from other brands of TV. 
5) I like to use the LED Strip instead of LED Light Bar. Both of these words are 
the same thing and same meaning. Please do not confuse. 
6) All the Programmer mention in this ebook is using the RT809F Universal 
Programmer. For Nand Flash it is using the RT809H Universal Programmer.

3) 2A DC-DC Step-up Module/Board (Optional)
Ampere Ioutput (max) = 2A (recommend use in between 1A) 
Input voltage = 2V~24V 
Output Voltage (max) = 28V (recommend use 26V or below) 
This module can easily adjust output as: 9V, 12V, 15V, 18V and 24V. 
4) Universal LED Driver Board for 10~42 inches LED TV (Optional) 
Vin (Voltage Input) = 10.8V ~ 28V 
Vout (Voltage Output) = 88V (max) 
I out (Ampere output) = 480mA (typically) 
Ampere output can be set in between = 10~1000mA 
Notes: Be careful to all types of Universal LED Driver Board. Even this board 
wrote can support 10.8V ~24V input voltage, but their output ampere will 
difference as below: 
When 24V input voltage (Vin): Vout= 75V, I out= 720mA (60W max) 
When 12V input voltage (Vin): Vout= 75V, I out= 400mA (30W max) 
* So it will affect the brightness of LED Light bulbs! That’s why the PSU board 
if just has 12V or 13V output voltage to inverter section need to add in a 2A

Learn How to Modify and Upgrade LCD TV to LED 
Backlight 
For the CCFL or normal type EEFL LCD Backlight, just removed their CCFL 
or EEFL lamps and replace with LED Strips. Make sure that the LED Strip size 
or their length is suitable for your panel. For the small inches LCD TV or LCD 
Monitor, most of their LCD backlight is design using Edge Light type. You 
need to remove their CCFL lamps from metal shield/cover of that Edge light. 
So when you buy the set of LED Strip with LED Driver board, make sure that 
you told the seller what’s type of LCD Panel is and their types of design. So that 
you can buy the suitable set of LED Strip + LED Drive Board to modify and 
upgrade your LCD TV backlight.

Notes: Because of this type of EEFL Lamp, so I decided to help him to modify 
and upgrade the LCD TV to LED Backlight! Important thing is the customer 
accepts my suggestion to modify the TV. 
Modify Case A- Failed: 
Before start to modify the LCD TV, make sure that all the parts and tools are 
ready to use. It will help us to do the job easily without any frustration. 
Step-1:
To do the PSU Self Test first, make sure all the voltages are appears correctly. 
Because of this PSU board (IP Board, BN44-00143A) just output 5V, 12V and 
13V only, no 24V. So its need to add in the 2A DC-DC Step-up Module to 
increase the 13V to 24V for LED Driver Board use. If not, the LED Backlight 
wills not working perfectly and their brightness is not enough. 
For the IP Board, we need to bypass their inverter section first. This IP board 
design is supply the 13V to their IQ1 Regulator IC and supply to their inverter 
control circuit. And another way is supply from PFC voltage to their inverter 
section. So removed the IQ1, J812, J813 and FI801 (T3.15A 250V fuse), their 
inverter section will stop work.

26 V5.0-OLED/LED/LCD TV Repair Tips
Step-2:
The Universal LED Driver Board needs these voltage line and signal lines to 
operate. They are: 
1) Vcc (Depend on the Universal LED Driver board their input voltage 
requirement) 
2) GND 
3) EN => same as BL_ON, SW and etc 
4) Vadj => same as PWM, P-DIM, ADJ and etc 
So find out these lines from the original IP board like photo below: 
Found PWM and SW pins: 
ImagineX ElectronicS
 
http://www.LCDRepairGuide.com/V5/
27 V5.0-OLED/LED/LCD TV Repair Tips
Found the Inverter supply voltage line-13V:
Step-3:
After found all these voltage and signal lines, we can start to modify the circuit 
now. Prepare the Universal LED Driver Board, LED Strips and the cables 
supply by the seller. 
ImagineX ElectronicS
 
http://www.LCDRepairGuide.com/V5/
28 V5.0-OLED/LED/LCD TV Repair Tips
Also prepare the 2A DC-DC Step-up Module to set the output voltage to 24V. 
Connect the Module input voltage from IP board 13V supply. After that use a 
screw driver to adjust it until the voltage output reach 24V like photo below:

* Please check all the connections are connected properly. Especially DON’T 
wrong connect their supply line! If not, it will damage the LED Drive Board or 
IP Board. Also make sure that DC-DC module is output 24V! 
If everything is ok, then we can try to power on the TV and see the LED Strips 
working or not. 
Yes, the LED Strips are all working now. So the next step to be put all the LED 
Strips x4 into the EEFL Lamp there. 
Step-4:
This step is to think how to put all the LED Strip into EEFL Lamp there. Also 
their cables need to manage it too. Because the cable some is long and some is a 
bit shorted.

some space to put it in. So try to do it now. 
Temporary put the LED Strip on EEFL Lamp and balance their distance in 
between the LED Strips:

tape until the plastic and front metal shield cannot close it properly. 
Removed the 3M Double Side tape paper and stick it on the EEFL Lamp. Also 
use the aluminum tape to close all the cables:

37 V5.0-OLED/LED/LCD TV Repair Tips
Analysis the problem now: 
1) Why the screen can saw all the LED light bulbs brightness? 
Answer: It could be the LED Strip put too near the Panel Glass and causing this 
symptom on the screen. 
2) Their total brightness for the screen it not good and bit darkness compare to 
the normal TV brightness? 
Answer: The LED Driver Board and ADJ signals, also MENU setting for 
brightness and contrast also try already, but still same problem. Looks like the 
LED Driver Board cannot supply enough Ampere for the LED Strips to provide 
morebrightness from it. 
Solution:
1) Removed the old EEFL Lamp and other unnecessary parts inside the panel. 
So the LED Strips not to put too near the Panel Glass. One more thing, if the 
LED Strip put too near the Panel Glass, it will damage the LCD Panel Glass 
rear polarizer film on the future. It is because of the heat generated by the LED 
Strips! 
2) The 4 x LED Strips is not enough to provide the good brightness to Panel. So 
will planning to put about 6 x LED Strips inside the Panel. The problem is that 
seller selling this LED Strips Kit set is just for 4 x LED Strips only and not 
support to 6 x LED Strips. So I will plan to replace another Universal LED 
Driver board to support 6 x LED Strips. 
Modify Case B- Successful: 
Follow by the Case A steps 1 to 3. Replace another LED Driver Board like 
photo below:

Driver Board connector pins and then change it to suitable for this board. When 
everything is ok, power on the TV now:

How to Connect from 4 x LED Strips to 6x LED Strips? 
This is a good question! How to modification the LED Strip connection from 4 
x LED Strips to 6x LED Strips. 
Because of this LED Driver board just supply 2 x LED+ Channel only. So their 
LED Driver Board specification is 88V (max), that’s mean each Channel of 
LED Strip cannot reach or over 88V (but recommendation for this board is just 
75V [max]). If we want to add in total 6 x LED Strips, that’s one channel is 3 x 
LED Strips. And these 3 x LED Strips total loading voltage cannot exceed 75V! 
After connected the 3 x LED Strips, use the LED Tester I’ve shown on this 
ebook, measure their voltage. So you know that it is below 75V or exceeded. If 
below 75V, we can use this Universal LED Driver Board to use 6 x LED Strips! 
The LED Strips connection from 2 to 3 x LED Strips is like below:

How to Programming the LED/LCD TV 
Mainboard Correctly
I’ve received lots of members email said they’re hard to learn how to 
programming the TV Mainboard. So this article will let you learn some of the 
basic information on how to programming the LCD/LED TV Mainboard 
correctly. 
IMPORTANT & WARNING!!! 
Before to do the Read/Write memory IC or MCU, or I call it as 
“Programming” action to the Main Board or Memory IC, please BACKUP the 
old & original firmware/data first!!! This step is very important and serious 
thing. But most of the repairers are lazy to do that. 
So when occurs the new programming problem in their TV Main Board or 
memory IC and they did not backup the original firmware, they will cry…Yes, 
this is not a joke, it is happened too often. No matter what brands or models of 
their Programmers, you must train yourself to do that first. 
One more thing, please use the Programmer original supply cables (VGA & 
USB). Don’t modify their length of the cables. It will affect the programming or 
Read/Write data in memory IC. Especially do the ISP Programming. 
Not All the Memory IC or MCU Chip Can Support by the Programmer 
Before you want to programming a memory IC or MCU (Micro-Controller Unit) 
chip, you must check your Programmer Supported IC List first. Yes, even the 
Programmer seller said it is a Universal Programmer, but it cannot support all 
types of memory IC and MCU Chip, it will depends on the model of that 
Programmer. So you need to check by yourself which Programmer is suitable to 
use in your jobs. 
If you want to update the TV firmware version, just go to the TV Brand official 
website there to download their latest firmware and follow their instruction to 
update.

In this article and other chapters, I will use this Universal RT809F ISP 
Programmer (http://www.lcdrepairguide.com/tools/) for your reference. 
3 Types of Programming Method for LED/LCD TV 
MainBoard
Actually they have 3 types of Programming Method for TV Mainboard. They 
are: 
A) Online Programming 
B) Offline Programming 
C) USB Pendrive/Thumbdrive 
Here is the description of these programming methods: 
A) Online Programming 
1) Online Programming also called as ISP Programming (ISP= In-System 
Programming). 
2) This type of programming method must supply the voltage to TV 
Mainboard to be successful Read/Write their memory IC or MCU chip. 
ImagineX ElectronicS
 
http://www.LCDRepairGuide.com/V5/
49 V5.0-OLED/LED/LCD TV Repair Tips
3) With Online Programming/ISP Programming, you can easy to read/write 
the TV Mainboard without to remove their IC or Chip from the Board. 
4) Some of the Mainboard Design need to login to their Service Mode to 
open the ISP feature first. After that the programmer can do ISP 
Programming to their Mainboard. Especially the some of the MST Chip 
solution Mainboard using in Konka, TCL TV. For example the Konka 
LC32ES62 TV. 
5) PROS & CONS for Online Programming: It is save time to do the 
Read/Write action to memory IC or MCU chip. Because we don’t need to 
remove that IC/Chip from the Mainboard, after that need to solder it back 
to Mainboard too. But the CONS is their Read/Write data some time will 
not accurate! That’s why I will recommend the repairer when using the 
ISP programming, need to do at least 2 times to Read or Write their data, 
after that compare their “Checksum” values is same or not. Be careful for 
the TV Main board design where their User Menu data will savein the 
flash memory there. So every time restart the TV, their Checksum values 
will difference. 
B) Offline Programming 
1) Offline Programming is to removed the memory IC or MCU Chip 
from TV Mainboard and put it in the Programmer Adapter to do 
the programming. 
2) This type of programming no need to supply voltage to Mainboard. 
3) All types of the Programmer can do this type of Programming. 
4) PROS and CONS for Offline Programming is their Read/Write 
data is high reliability than Online Programming. When the 
memory IC/Chip damage, it can easily to detect it by Offline 
Programming method. But their CONS is too much trouble to 
remove the IC/Chip from Mainboard. After that need to re-solder it 
back to Mainboard. Some of the repairer because of this thing and 
damage the Mainboard circuit lines. 
5) But the good news is it has a special tool to ignore to remove the 
IC from Mainboard. This tool is: IC Clip. But it is not for MCU 
Chip. The IC Clip like the photo below:

50 V5.0-OLED/LED/LCD TV Repair Tips
C) USB (PenDrive/ThumbDrive) 
1) The TV can use USB Pendrive as a memory the Mainboard firmware. 
After that follow the instruction to insert it into the TV USB port to 
update their firmware. 
2) This method just for add in new software features or correction some 
small problem through update their firmware by USB Pendrive. 
3) This method need to supply voltage to their Mainboard to perform their 
firmware update. 
4) If the TV or Mainboard not working, this USB method cannot be use.

How to Programming the LED/LCD TV Mainboard 
Inside the LED/LCD TV Mainboard, they have several types of memory IC and 
MCU chip. Below are the types of memory IC in TV Mainboard: 
1) 24 Series Memory IC (seldom use 93 Series Memory) use in: 
=> EEPROM, HDCP EEPROM and EDID (DDC) EEPROM 
# You can use the RT809F doing Offline Programming to Read/Write their data 
into the memory IC. 
2) 25 Series Memory IC use in: 
=> Serial Flash Memory IC 
# You can use the RT809F Programmer to do Offline Programming or Online 
Programming to Write/Read data into this Flash Memory IC. 
3) H27Uxxx, K9Fxxx, TC58NVGO & etc Series Memory IC use in: 
=> NAND Flash Memory IC (some older TV will use NOR Flash & eMMC) 
# You can use the RT809H Programmer to do the Offline programming to 
Read/Write their data into the memory IC.

Why you need to programming the TV Mainboard? Because the TV is can’t 
start-up problem, so I want to try programming the Mainboard and solve the 
problem. Or I want to copy their firmware to prepare future use. These two 
answer is most of the TV repairer gave. 
Q1: How to Programming the TV Main Board? 
A1: Normally the Programmer when using the ISP (Online programming), it 
will go to detect their Flash memory. The flash memory is mean of the external 
25 series Flash memory IC on Mainboard. So the Programmer software will 
shows like 25 xxx detected and prepare to Read or Write command. 
Actually we can remove the 25 Series Flash Memory directly from Mainboard 
and to do the Offline Programming to Read (Copy) their firmware/data from the 
25 series Flash Memory IC. And then save the firmware into the 
computer/laptop prepare for future use. 
Q1: How to Copy the Firmware from Main Board? 
A1: Like a said on the above, you can remove the 25 series Flash Memory IC 
from Mainboard and to do the Offline Programming. After click on the 
Programmer Software button “Read” (Copy) the firmware from 25 series Flash 
Memory IC, and then save it into the computer/laptop. 
Notes: Most of the time (about 80%) to using Programmer on TV Mainboard is 
because of the TV Mainboard Can’t Start-up the TV. Excluded the hardware 
problem in Mainboard (like regulator IC, crystal, reset circuit & etc, for more 
details, please do refer to my V3.0 & V4.0 ebooks), so the higher chances is 
their 25 series Flash Memory firmware corrupted or the 25 Flash IC defective. 
Also don’t forget their NAND Flash IC. It also can cause the TV can’t start-up. 
If you want to programming the NAND Flash memory IC, please do carefully, 
because some of the NAND Flash IC need to programming their MBOOT or 
BootLoader first, after that is the main firmware for that NAND Flash Memory 
IC. Also for programming the NAND Flash, you need choose a Pro 
Programmer to support this type of memory IC.

How to Programming the Universal TV Mainboard 
When we change a new Universal TV Mainboard to a TV, we need to change 
the firmware to suitable of the TV Panel model. If not, the TV will no display, 
funny color and display & etc occur. 
So the Universal TV Mainboard has their own firmware list to suitable different 
Panel. If you buy a new Universal TV Mainboard, make sure to tell the seller 
your TV panel part number. After the correct version and panel types firmware 
is ready, just copy that file into the USB Pendrive and follow the instruction to 
update the firmware to the latest one to suitable the TV Panel. 
Some of the Universal Mainboard is built-in the different Panel type firmware. 
Just follow some instruction to change the Panel type without using 
Programmer or USB update. 
How about the Universal TV Mainboard firmware failure? 
ImagineX ElectronicS
 
http://www.LCDRepairGuide.com/V5/
55 V5.0-OLED/LED/LCD TV Repair Tips
If this is the problem in this type of Mainboard, you need to use the programmer 
to do the offline programming to their flash memory IC. Most of the time, you 
can solved the problem easily if you’ve that Mainboard firmware. 
Where to Find or Get the TV Firmware?
Before to programming the firmware, make sure these firmwares you get are 
same as your TV: 
1) TV Model 
2) Mainboard Part number (Important) 
3) Panel Part Number (Important) 
* For example: If the firmware same Mainboard Part number but not same the 
Panel Part number. If that Panel part number also show the same inches Panel, 
then you should give it a try. Make sure that you backup you old/original 
firmware first! 
You can get the TV firmware from: 
1) Forum website- Ask the member who have that model TV, Mainboard part 
number and Panel part number firmware. 
2) ASP Site- If you’re the Authorized Service Provider, you can get the 
firmware version from company. 
3) Universal Board Seller- If you bought the Mainboard from them, you must 
ask them to provide such firmware to use. 
4) Find Website Selling this Firmware- I found that some of the website they 
selling the TV firmware. But the model is not much to choose. 
5) Ask Your Local Repairer/Friend- Normally the repairer they will backup 
some local TV model firmware to prepare future use. 
6) Find a Working TV Mainboard and Copy the Firmware from it- You 
can try to find who/repair friend has this model of TV Mainboard and ask them 
to borrow the board to copy their working firmware.

A Superb Secret Revealed on 
How to Repair LCD/LED TV Mainboard 
This is another good repair tips on repairing the LCD/LED TV Mainboard. The 
Mainboard repairing method for this article, I call it as: 
“TV Start-Up Log” 
Most of all modern LED/LCD TV has this “TV Start-up Log” inside their TV 
Mainboard. I think after the year of 2008 model TVs will have this info log 
inside the TV. 
So what is the TV Start-Up Log? The TV Start-Up Log like the Laptoppower-
on sequence. But the TV Start-up Log is a TV Mainboard boot up sequence. All 
the process is operated by the TV Mainboard MCU (Micro-Controller Unit) 
Chip firmware. 
When the TV power on, the MCU will first detect:
1) DDR (DDR SDRAM) version and in between DDR and the Main Chipset 
(CPU) communication lines is OK or not. 
2) If the above device normal, it will pass and detect the next devices. The next 
device is to detect their BootLoader (U-Boot or MBOOT) version and their 
operation. If the detection found any error or can’t detect the device, it will stop 
there and not running their TV Start-up Log. 
3) Next will be their Main Program (Firmware) on NAND Flash. As usual it 
will detect their NAND Flash version and operation status. If ok, it will pass to 
next devices. 
4) Finally will detect their USB, Sound, Tuner & etc I
2
C circuits’ devices
(like EEPROMs). 
* When the MCU pass all the above detection, finally the MCU will send out 
the Power On signal to start-up the Power Supply/PSU. So the TV can operate 
normally. If not pass the detection, it will stop on the device was detected not 
pass. So this TV symptom will looks like Can’t Start-up TV!

What’s the benefit of this TV Start-Up Log help to the 
repairer? 
The modern LCD/LED TV Mainboard have lots of different types Memory IC. 
And their design is quite small size but the pins of IC are many! Not only that 
the Mainboard design at least double layer now. That’s why, how repairer to 
repair the TV Mainboard in components level? If you don’t know this TV 
Mainboard secret, I believe that you don’t want to repair it, but just replace it. 
With this TV Start-up Log, you can easily to know what’s wrong in TV. Like 
we learn from the previous V3.0 & V4.0 the Mainboard repair skills, plus this 
TV Start-up Log will increase the successful rate in TV Mainboard repair! 
Again how this TV Start-up Log help to us? Ok for example, when a TV 
symptom is power LED light lit but TV can’t start-up. So after check all the 
hardware on Mainboard like: voltage regulator IC, voltage input for Main Chip, 
reset circuit, crystal waveform and etc all Ok. So what can we do know? 
So we can try to programming their 25 series Flash memory with the correct 
model and version firmware. Or we can do the TV Start-up Log first! After the 
TV Start-up Log appears, we can roughly know where or which device is 
defective. So we can directly go to that device section and checking it. So it will 
save lots of the time to guess what the problem in Mainboard if checking all 
hardware components in good condition. 
How to Operate the TV Start-up Log?
The TV Start-up Log need to use a Programmer can support this feature. For 
example the RT809F Universal ISP Programmer. To run the TV Start-up Log, 
these two software can operate the TV Start-up Log. They are “Init. Info Serial 
Print” or “SecureCRT”. You can use below software to see the TV Start-Up 
Log to learn more about the TV Mainboard info.

Example Problem TV Start-up Log: 
Good vs Bad values. 
1) 8M/S Series DDR Abnormal 1: 
The TV Start-up Log shows that 2 x DDR detection normal. But the row-4 
shows that detection data error in between the Main Chip with DDR. That 
position is for DDR1. That’s mean the problem is on the DDR1 damage or dry 
join of DDR1. (After repair this TV, confirm is their U12 DD1 dry join only). 
2) 8M/S Series DDR Abnormal 2: 
DDR1 detected clock checksum error. On the row-4 detection, found that Main 
Chip through DDR input info is nothing, it could be the Main Chip damage or 
dry join. Or it may be the DDR1 dry join too. After repair, confirm that’s the 
Main Chip dry join only. Just re-flow with BGA is Ok now. 
ImagineX ElectronicS
 
http://www.LCDRepairGuide.com/V5/
69 V5.0-OLED/LED/LCD TV Repair Tips
3) 8M/S Series DDR Abnormal 3: 
The row2 and 3 show both DDR detection failed. And the row 4and 5 show that 
DDR cannot receive the data from Main Chip. Check the DDR supply voltage 
pins is normal. So it could be the Main Chip abnormal or dry join. After repair, 
confirm that’s the Main Chip damage. (Sometimes when DDR supply voltage 
pins are open, it also can cause this type of error message). 
4) 8M/S Series DDR Abnormal 4: 
First DDR detection failed. So it could be the first DDR damage or Main Chip 
(CPU) and first DDR in between the network resistors is dry join. But mostly is 
the Main Chip damage. How to know Main Chip damage? Just measure the 
Main Chip core voltage supply LDO output and the Ground ohm values, 
normally is just 60 ohm. Or use the finger to touch the Main Chip temperature, 
when just power on TV, if their temperature increase quickly, that’s mean their 
Main Chip is damage.

70 V5.0-OLED/LED/LCD TV Repair Tips
5) 8M/S Series Flash Abnormal 1: 
The TV Start-up Log shows that DDR and U-BOOT is pass detection. When 
running till the NAND, it cannot identify the Flash and cannot read their data. 
Normally this type of problem just using the Programmer to programming their 
main firmware is ok. If failed to do the programming to NAND, please replace a 
NAND Flash. 
6) 8M/S Series Flash Abnormal 2: 
The error code shows that the NAND Flash have Bad Block and need to replace 
it. 
ImagineX ElectronicS
 
http://www.LCDRepairGuide.com/V5/
71 V5.0-OLED/LED/LCD TV Repair Tips
7) 8M/S Series Flash Abnormal 3: 
Cannot load root, the flash have unrecognized area. Normally this problem is 
their NAND or EMMC damage and need to replace. 
8) 8M/S Main Firmware Abnormal log: 
The BOOT normal, but the Main Firmware is missing. Need to re-programming 
their Main Firmware and TV is ok now. 
Notes: The higher failure rate is their Main Chip and DDR (also included the 
lines in between both of them). But most of the time is their resistor network or 
Main Chip dry join! If even check with the TV Start-up Log also can’t help, we 
can try to re-programming their BOOT and Main Firmware of NAND Flash. 
This method can solve lots of TV Mainboard problem!

New PSU Self Test Method for Modern TV 
Nowadays, new design LED/LCD TV is using different standby voltages. 
Normally the older models of LCD/LED TV their power supply unit (PSU) is 
generated 3.3V or 5V standby voltages. But the latest models of LED/LCD TVs 
is using 8V (7.8V) now or more! For example the LG 2015/2016 LCD/LED 
TVs that use 13.2V as Standby voltage. For 2016 LCD/LED TV Models that 
use 8V Standby voltage when it start-up/run is 18V! If you use the old PSU Self 
Test method, it could be damage the PSU board. 
A new method or a tool called it as “PSU Self Test 3V-JIG”. 
With this 3V-Jig you can use it on old or new models LED/LCD TV without 
risk to damage the PSU board. So this simple 3V-Jig can use to troubleshoot 
suspected power supply (PSU/SMPS) and/or backlight (LED/LCD) issues. This 
3V-Jig can also work on any LCD/LED/OLED TV no matter the Standby 
Voltage output! 
How to Build a PSU Self Test 3V-JIG
The following items will be required to build the 3V Simple Jig: 
 AA size 1.5V Batteries x 2 units 
 20 Gauge wire, 3 each, at least 12” long (2 Red and 1 Black)
 20 Gauge wire , 1 each, ¾” long (Black) 
 Heat Shrink, 3 each, 1/16” DIA x ¾” L 
 Sewing Needles. 3 each, 0.04” DIA x 1.5” L

Using the 3V-JIG for Testing the PSU (Test 1 of 2) 
How to Identify You Need to Use this JIG:
Look on the Power Supply (PSU) for the Voltage Label for the connector that 
goes to the Main Board, example LG 49LF6300 PSU connector shown on 
below: 
Note that the output power from the SMPS/PSU to the Mainboard during Stand-
By or Run is approximately 13V. (Standby: Approx. 12.5V; Test Pin-1 
Condition: 13.2V) 
Preparing the TV for Test-1: 
AC is not applied. “Unplug the Mainboard” connector that comes from the PSU. 
On the Mainboard, unplugged connector end, push in the following needles as 
described below. (Use the Mainboard unplugged connector to insert the needles 
from the 3V-JIG. 
Procedure:
1) Push one (+) Red wire needle into PWR_ON pin 1. Push one (-) Black wire 
needle into Ground pin-3. (You can also use Chassis Ground). 
2) Apple AC power. This turns on the Power Supply. Test the 13.2V that go to 
the Mainboard. Pin 4 through pin 8. (STBY: Approx. 12.5V, Test-1 Condition: 
13.2V)

3) If Power Supply fails to come on or start-up, that’s mean the Power Supply is 
defective and need to replace. Or you can concentrate to do the components 
level repair. 
4) If troubleshooting TV for “No Turn On” symptom, and the Power Supply
now test good, that’s mean the problem is on the Mainboard. So you can 
concentrate to check and repair the Mainboard or replace it. 
Notes:
A) Highly recommend to power off the TV SMPS board, and connect theStandby line 13.2V pin/s with a 24V 5~10Watt DC light bulb as a loading to 
testing it again to make sure that SMPS board is working properly. 
B) If the Power Supply board is not producing Standby voltage 13V with the 
Mainboard disconnected (pins-4~12), replace the Power Supply or you can 
concentrate to check their standby circuit on PSU board.

Backlight Testing Procedure: 
5) Remain the Power Supply Testing connection. Push one (+) Red wire into 
DRV_ON pin-11. 
6) Apply AC Power. This turns on the Backlights. 
7) The Backlights should come on, (Check visually). 
- Recheck all voltages from the SMPS to the Main. If Backlights are on, 
Backlight Power is OK.

Backlight Power Connector: 
At the top of the Power Supply is a 4-pin connector going to the Backlight 
LEDs. The two labeled LED+ will be the Power pins. See silkscreen voltage 
output table for voltages. LED- is the grounding pulse feedback pin for the bank 
of Backlight LEDs. 
Using the 3V-Jig for Troubleshooting Backlights 
How to Identify the Power for Backlights:
Look for the Voltage Label on the Power Supply to know what the backlight 
voltage should be. As an example, on the below is from a 49 inches LG 
49LF6300 TV. One pin (LED+) will have 175V and another one pin (LED+) 
will be 117V.

Troubleshooting the Backlight Connector (Backlight not lighting): 
1) Check the voltage at the 2 Backlight LED power pins labeled (LED+), see 
chart. If Voltage is correct or goes high then drops down to about 50% to 75% 
of the correct voltage you can assume Power is OK. This may indicate an 
internal short in the backlights, for example the LED strip light bulb leakage. 
But wait until you complete Check 2 below. 
2) Next Check the 2 Backlight (LED-) pins. 
a) If LED- pins are 0V. Normally these pins should be (4V~10V). If they 
are 0V, it can be assumed the Backlight LEDs strip are open and need to 
repair/replace. 
b) LED- pins are Hi (approx. 30V). This would indicate an open driver 
which is located on the Power Supply. Use a 100 ohm resistor and place one 
end on Chassis Ground. Place the other end on the High LED- pin. Apply power, 
if Backlights turn on, you are assured the Power Supply is defective. 
Notes:
For older models of LCD/LED TV with 3.3V, 3.5V & 5V Stand-By voltage 
generate from Power Supply board, you can refer to my V3.0 & V4.0 PSU Self 
Test Method to testing it.

Secret Revealed on How to Fast Check the 
Bad LED Light Bulb in LED TV Backlight 
Lots of the modern LED TV has a circuit protection design to protect their 
backlight system. When the system detects something wrong on LED strip (or 
LED light bulb/s) it will cause the LED Driver Board or PSU+ LED Driver 
shutdown the backlight. So the symptom will looks like LED TV Backlight on 
then shutdown within 1~2 seconds. 
With this little time, even we have dismantled the LED Panel, but we still can’t 
see which LED Strip/s or LED Light Bulb causing the Backlight system 
shutdown. Because of the backlight shutdown, so we can’t use the volt meter to 
testing their LED Strip voltage to compare to each other. 
So what can do now? If you don’t know this method, I believe that you will 
measure the LED Light Bulbs one by one! It will waste the time to checking it. 
Sometimes, we can direct see the burn LED Light bulb on the LED Strip and 
know that LED Strip is bad. But most of the time is not. So we need to learn a 
new method to solve this problem! 
The answer for this new method is: “Using Your Mobile Phone Video Mode”!!

82 V5.0-OLED/LED/LCD TV Repair Tips
Here are the steps of “How to use Mobile Phone/SmartPhone Video Mode” to 
find out the faulty LED Light Bulb/s from LED TV Backlight: 
1) After dismantled the LED Panel, we can see the Full LED Backlight (not the 
Edge-Lit type LED Backlight). 
2) Use the SmartPhone and open the Video App. After that the camera direction 
will shot on the Full LED Backlight like photo above. Click start to record 
video now, and then power on the TV. The LED Backlight will lit and shutoff 
very fast till like haven’t lit before. Stop record the video now. 
3) This is time to play back the video, ‘Pause’ the video when you saw their 
LED light bulbs lit. Actually that’s the Infra-Red light not the LED light bulb 
full light. This is because when LED light bulb supply with the input voltage, 
instantly it will generate the Infra-Red first, after that the full LED light lit! 
That’s why, when the LED Tv Backlight system protection too fast until we 
can’t see it from our eyes, but the Mobile Phone/SmartPhone camera can “see” 
and record their Infra-Red light before it shutdown the backlight.

easily! 
Process to Troubleshooting and Repairing 
LED TV Backlight & LED Strip 
A Haier LE50A900K LED TV complaint problem was TV Backlight on then 
shutdown quickly within 1~2 seconds. But the TV sound is normal. Use torch 
light to check the screen and found the darkness display is present. So confirm 
the problem is on the backlight system. 
This TV backlight LED Drive/Driver board is using L500H1-4EB. Use the LED 
Backlight Tester to testing their LED Connector LED+ and LED- channels. 
Found one of the channel LED Strip voltage a bit high than the other channels 
LED strips. Suspect this channel LED strip is abnormal and cause the LED 
Driver board start-up their backlight protection system to shutdown the 
backlight. So we need to dismantle the LED panel to check and repair it. Below 
is the process to dismantle LED Panel: 
Steps: 
1) Remove all the PCB board from TV. After that, flip the LED panel their LED 
screen glass was on the above and in front us now. Remove the Panel metal 
shield.

2) Release all the screws from T-con board, Source Driver board and etc. 
Remove all the cable/s and cable/s connected to Source Drive board. Make sure 
their Source Drive board, Gate COF IC and Panel Glass are freely now. If not 
you will easy damage their COF contact ACF glue and cause the screen display 
vertical lines/bars. After that using the Vacuum Pad to safety remove the Panel 
Glass and put it in a clean and safe place.

After removed their backlight sheets, you can see their LED strips was put on 
the left and right side, each got 2 LED strips. 
4) Use the LED Backlight Tester (this Tester also can test LED strip and LED 
light bulb too) check all these LED Strips and found one of the LED Strip got 
one LED light bulb failed. This is the LED light bulb cause the backlight 
shutdown! This LED strip voltage is a bit high than the other LED Strips. Use 
the utility knife to remove double side tape of the LED Strip from itsmetal 
cover. So it will not bending the LED Strip with the utility knife.

defective LED light bulb/s to repair the LED Strip. 
WARNING: Before proceed to dismantle the LED Panel, you must ask the 
permission from customer. Because it will take risk when dismantle LCD/LED 
Panel. Sometime after finish repair or replacement the LED strip, the LED 
screen will show vertical lines/bars or horizontal lines/bars on the screen. It was 
because when process to dismantle the LED Panel accidently impacts their

How to Remove the LED Light Bulb from 
LED Strip Easily?
The LED TV has lots of faulty in their backlight system, especially the LED 
Strip and their LED light bulb/s. So we will facing many LED TV need to 
replace the new LED Strip. But the problem is, they have many types of the 
LED Strip design with different LED light bulbs. The LED light bulbs have 
different voltage types, normally use are 3V, 6V and the new one is using 12V 
now! So it will have different voltage input for the LED Strips and different 
sizes (or LED Light bulbs quantity in a LED Strip) of LED Strip. 
So the spare part stock will difficult to store different types & models LED 
Strips. The solution to solve this problem is to just replace their LED Light 
bulb/s only! It will save money, time and space to store the spare parts. 
The question is how to remove the LED light bulb from LED Strip? Can I use 
the soldering iron to remove it? Yes, some of the good soldering iron can do 
that, but not perfect and sometimes can damage the LED Strip circuit or that 
LED Light bulb/s. 
Finally found some of the good solution to solving this problem. These 3 
solutions can help to easily remove the LED Light bulb/s from the LED Strips! 
Solution-1:
Use the Hot Air Rework Station to remove LED Light bulb/s. 
ImagineX ElectronicS
 
http://www.LCDRepairGuide.com/V5/
90 V5.0-OLED/LED/LCD TV Repair Tips
A suitable temperature to remove the LED Light Bulb from LED Strip is about 
200 C ~ 280 C. Some will try until 350 C! So it will depend on your device 
performance. So starting with the lower temperature first! Because of each 
model and brands of Hot Air Rework Station their quality and accuracy is 
difference. Before using it to do the removing LED light bulb, so we need to use 
the bad or old LED Strip to testing that Hot Air Rework Station temperature 
first. So that we can find out the perfect temperature values for that Hot Air 
Rework Station to easily remove the LED light bulb and without damage to it. 
Solution-2:
Use a Hot Air Gun to remove the LED Light Bulb like photo below:

Solution-3:
This method is seldom repairer to using it. This is a PTC Heater. Yes, we can 
use a PTC Heater or PTC Thermistor to remove the LED Light Bulb! The PTC 
Heater just takes about 30 seconds to warm up, after that it can start to use. Its 
input voltage is: 220Vac, wide surface temperature is about 250 (when input 
voltage is 220Vac) degree Celsius +/- 10 . The PTC Heater is like photo

This PTC Heater is easy to use, constant heating, automatic temperature control 
without any temperature-controlling system and the important thing is it is 
cheap! Just below $5 USD (2017) only. But the weakness point is their input 
voltage cable/s easy to break. 
Some of the repairer also using this PTC Heater to remove the FPC connectors, 
the FPC connector is from T-con board or Mainboard. But it must look at the 
situation of that T-con board bottom side, that’s no any SMD components on 
the bottom foil side.

Conclusion:
The Solution-1 & 3 is better to use than Solution-2. But I will recommend using 
the Solution-3. Because it is easy to use and nothing to set (temperature setting), 
and important thing is its price cheap. If your budget is Ok, then you can buy a 
high price “Constant Temperature Pre-heater” like photo below: 
This Constant Temperature Pre-heater normally using in Mobile Phone repair. 
But it can use to remove the LED Light Bulb easily. But the price is not cheap.

2) PSU Board: 5800-P40TOS-00 
TV Model: Skyworth 42L01HF LCD TV (Chassis= 8M19)
a) Symptom: TV Can’t Start-up 
When TV power on, measure the PSU standby voltage has 5V 
output, but no 12V & 24V output. Using the PSU self test method, found the 
24V line output voltage increase to 27V after that PSU cutoff. That’s mean the 
PSU is overvoltage protection now. Check the 24V line voltage regulator circuit, 
all components normal. Direct replace IC604 (KA431) and IC607 (L6599) also 
same problem. Check IC607 corresponding components all looks good. Try to 
power on the PSU again, when check the PFC voltage and found it’svery high 
till 460V! It is because of the PFC over voltage causing the 24V output increase? 
Check the PFC feedback circuit now. Found their R621 (560K) 
was opened circuit. After replace R621, their PFC voltage back to normal range 
is about 390V now. The PSU is ok now and output the 12V & 24V. 
Repair : R621 (560K ohm) 
b) Symptom: No 24V output, but 12V is normal.
Power on TV, check IC607 (L6599D) voltage supply pin is normal. 
Power off the TV and check IC607 corresponding components is normal. Direct 
replace IC607 also same problem. Further check the Q612 & Q614 found Q614 
when power on, it will instantly breakover/work. After analysis the problem, it 
could be on the primary side of transformer. First check their voltage feedback 
circuit, because when 12V &24V have normal outputs, their feedback 
optocoupler secondary side has 1V voltage there. So power on the TV and 
ImagineX ElectronicS
 
http://www.LCDRepairGuide.com/V5/
97 V5.0-OLED/LED/LCD TV Repair Tips
check voltage feedback circuit optocoupler secondary side have voltage, but 
quickly drop to 0V. Try to remove the C669 (1000P) capacitor from circuit. 
Power on the TV, the PSU is working and output the 12V & 24V normally. 
Replace a new C669 capacitor, the PSU is working perfectly. 
Repair : C669 (1000P = 1nF ) 
c) Symptom: TV Screen Flashing Randomly 
This TV after working about half an hour’s, the TV screen will 
start flashing and occur randomly. When the problem occur their PSU 24V line 
output drops to 21V only. But disconnect the loading of 24V line, the voltage 
will back to normal 24V. Check the 24V line corresponding components and 
their circuit line, found that the problem was because their 24V circuit line 
output D617 one of the pin circuit line is crack. Repair the crack line with just 
re-solder it, and the problem solved. 
Repair : 24V circuit line nearby D617 pin circuit line crack. Just re-solder 
it problem solved. 
Notes : For this PSU board, when the screen flashing problem occur, also 
need to check their R621 and R622 (both 560K). When these two resistor values 
drop to 500K ohm (normal 560K) it will cause the screen flashing too. 
2) PSU Board: 168P-P42TTS-00 
TV Model: Skyworth 42L01HF LCD TV (Chassis= 8M19)
a) Symptom: TV Can’t Start-up but the Standby LED light is lit. 
Use PSU self test method and found PSU board can generate 
standby 5V, but no 12V & 24V output. So the problem is in PSU board. Check 
PSU board PFC voltage is about 300V only (Normally it is about 380V at C523 
+ve pin). That’s mean their PFC circuit is not working. Check the PFC control 
IC IC609(NCP1653) pin-8 voltage supply input is 0V! Normally it is about 15V. 
Trace the voltage supply line to Q609 and ZD300, found ZD300 (15V) zener 
diode is damage. After replace ZD300, the PSU is ok now. 
Repair : ZD300 (15V) zener diode

output just 0V. Replace their U006 (RT8110), after that power on the TV, the 
RT8110 output 5V. But just after about 1~2 minutes, same problem again. 
Check the U006 corresponding components and found the U006 pin-7 and 
C001 in between has a loophole there. Check the loophole ohm values it shows 
nearly 2Kohm! Looks like the loophole inside line break and causing no 5V 
output. Connect a wire to bypass this loophole. Finally this problem solved!

(1) PWR_ON turns on the 12V and 24V lines. It also 
turns on the backlight power, but it's 85.1V P801 pin 2 
(85.6V P801 pin 4) Backlights are not on.
(2) DRV_ON (INV_ON from Main) turns on the 
Backlights. Backlight power is 116.4V P801 pin 2 
(116.7V P801 pin 4).
(3) P-DIM controls the backlight brightness. Controled 
by Cust. Menu, Video, Backlights. Range 0% to 100% 
directly proportional to DC voltage to Backlight 
brightness. 
P-DIM is actually a PWM signal.
If P801 is disconnected, the backlight power P801 pin 
2 or pin 4 will rise to 146.6V and fall to 130.5V 
repeatedly.
Note: If the top or bottom of the picture is exhibiting a dimmer backlight level than the 
other or the overall brightness seems dim, be sure to first check the customer’s Menu 
setting for Backlights. Raise the percentage and see if the overall brightness returns to 
normal. 
If not, Check the P-DIM level, it should rise with the percentage shown on screen. 
You can also test either the Top or Bottom blocks functionality by grounding the 
return path signal (using 1KΩ resistor). 
LED TOP OR BOTTOM BLOCK TEST (DIM OR DARK PICTURE AREA):
Turn the Brightness, Contrast and Backlights all the way up. Confirm 116V on P801 pin 2 
and pin 4.
Confirm P-DIM is approx. 3V. Using a 1KΩ resistor, (one end on ground), jump the block 
grounding pins on P801 (Top is controled by P801 pin 1 and the Bottom is controlled by 
P801 pin 3), while observing the picture. Each block should turn on brighter. (If No: Bad 
Panel, If Yes: Bad SMPS).

WARNING: Do not add or remove jumpers with Power Applied.
SMPS TEST 1: To Force Power Supply On without the Main Board.
Disconnect the P200 on the Main board.
SMPS must be producing 13.2V (12V in STBY).
(A) Use a 10K resistor and jump pin 5 (13.2V) to pin 1. Test Voltage Outputs 
13.2V to Main. (86.9V Backlight power but the Backlights are not on at this time). 
LED Ground Return Line is (9.15V).
Remove AC power. Leave the jumper in place.
SMPS TEST 2: (Turning on the Backlights)
(B) Use a 67K resistor and Jump pin 7 (13.2V) to pin 11 (DRV-ON). Apply AC 
power, the Backlights should turn on. Note, the LED B+ will now read 116V P801 
Pin 3 (174.6B Pin 7). 
LED Ground Return Line is (0.96V). P-DIM P201 (pin 4) pulls up to 3.35V.

(1) PWR-On Pin 1: Turns on 13.2V to the Main. No backlight power at this time. 
 Backlight Power is 86.9V.
(2) DRV_On Pin 11: Turns on the Backlights. Backlight power goes to 116V 
 P801 Pin 3 (174.6B Pin 7).
(3) P_DIM#1 Pin 12 and P_DIM#2 Pin 2: Will vary according to incoming video 
 IRE level and OSD Backlight setting Output from the Video Processor. 
 It is then routed out P200 and sent to the LED Driver IC on the Back of 
 the SMPS. Range 0.2V~2.60V. 
Note: If the top or bottom of the picture is exhibiting a dimmer backlight level than the 
other or the overall brightness seems dim, be sure to first check the customer’s Menu 
setting for Backlights. Raise the percentage andsee if the overall brightness returns to 
normal. 
If not, Check the P-DIM level, it should rise with the percentage shown on screen. 
You can also test either the Top or Bottom blocks functionality by grounding the 
return path signal (using 10KΩ resistor). 
LED TOP OR BOTTOM BLOCK TEST (DIM OR DARK PICTURE AREA):
Turn the Brightness, Contrast and Backlights all the way up. Confirm 120V on P801 pin 3 
and 180V on pin 7.
Confirm P-DIM is approx. 3V. Using a 10KΩ resistor, (one end on ground), jump the block 
grounding pins on P801 (Top is controlled by P801 pin 1 and the Bottom is controlled by 
P801 pin 5), while observing the picture. Each block should turn on brighter. (If No: Bad 
Panel, If Yes: Bad SMPS).

If P801 is disconnected, the backlight power will start at 49V, then jump to 
69V and then fall back to 49V. Warning: Backlight power is slow to bleed 
down after power off, connected or disconnected.
WARNING: Do not add or remove jumpers with 
Power Applied.
SMPS TEST 1: To Force Power Supply On without 
the Main Board.
Disconnect the P13002 on the Main board.
(A) Jump pin 5 (3.5V) to pin 1. Test Voltage Outputs 
12V, 24V to Main. 
(47.34V Backlight power but the Backlights are not on 
at this time). 
LED Ground Return Line is (0.62V).
Remove AC power. Leave the jumper in place.
SMPS TEST 2: (Turning on the Backlights)
(B) Jump pin 8 (3.5V) to pin 2 (DRV-ON). Apply AC 
power, the Backlights should turn on. Note, the LED 
B+ will now read to 64.68V. 
LED Ground Return Line is (1.07-1.38V). P-DIM P201 
(pin 4) reads 3.52V.
For DC voltages
See P201 Chart
132 Total LEDs, 66 LEDs per/Strip.
2 boards per/strip. (11 LEDs per/board) 12 columns.

Front IR/Joy Stick
Top pins on 
connector
are odd numbers.
WARNING:
Be sure to install the screws in the 
T-CON board before applying power. 
Damage to the board will occur.
Note: If a part of the picture is exhibiting a dimmer backlight level than the other or the overall brightness seems dim, be sure to 
first check the customer’s Menu setting for Backlights. Raise the percentage and see if the overall brightness returns to normal. 
If not, Check the P-DIM level, it should rise with the percentage shown on screen. 
You can also test any of the 12 blocks functionality by grounding the return path signal (using 1KΩ resistor). 
LED TOP OR BOTTOM BLOCK TEST (DIM OR DARK PICTURE AREA):
Turn the Brightness, Contrast and Backlights all the way up. Confirm 64V on P210.
Confirm P-DIM is approx. 3V. You can turn on a Block of LEDs by using a 100 ohm resistor from any test point EL76 – EL87 to 
Ground.
The Power Supply must be producing the 64V for the Backlight B+.
Failure to use a resistor will damage the panels backlight and may also damage the power supply.

Joy Stick / IR
Note: If the top or bottom of the picture is exhibiting a dimmer backlight level than the other or the overall 
brightness seems dim, be sure to first check the customer’s Menu setting for Backlights. Raise the 
percentage and see if the overall brightness returns to normal. 
If not, Check the P-DIM level, it should rise with the percentage shown on screen. 
You can also test either the Top or Bottom blocks functionality by grounding the return path signal (using 
1KΩ resistor). 
LED TOP OR BOTTOM BLOCK TEST (DIM OR DARK PICTURE AREA):
Turn the Brightness, Contrast and Backlights all the way up. Confirm 120V on P801 pin 2 and 178V on P801 pin 4.
Confirm P-DIM is above 2V. Using a 1KΩ resistor, (one end on ground), jump the block grounding pins on P801 
(Top is controlled by P801 pin 1 and the Bottom is controlled by P801 pin 3),. while observing the picture. Each 
block should turn on brighter. (If No: Bad Panel, If Yes: Bad SMPS).

SMPS TEST 1: To Force Power Supply On without the Main Board.
Disconnect the P2300 on the Main board.
(A) Jump pin 3 (3.5V) to pin 1. Test Voltage Outputs 12V, 24V to Main, Note: 
Backlight power is 85V P801 pin 2 and 85.1V P801 pin 4. Remove AC power. 
No Backlights at this time. 
LED Ground Return line: 7.83V P801 pin 1 and 0.04V P801 pin 3.
SMPS TEST 2: 
(Turning on the Backlights) 
Leave 1st jumper in place. 
(B) Jump pin 5 (3.5V) to pin 2 (DRV-ON). Apply AC power, the Backlights 
should turn on. Note, Backlight Power (BL+) Backlight power is 115.8V P801 
pin 2 and 173.4V P801 pin 4.
LED Ground Return line: 0.83V P801 pin 1 and 0.82V P801 pin 3.

(1) PWR_ON: turns on the 12V and 24V 
lines. It also turns on the backlight power, but 
it's 85V P801 pin 4 (85.1V P801 pin 2) 
Backlights are not on.
(2) DRV_ON: (INV_ON from Main) turns on 
the Backlights. Backlight power is 173.4V 
P801 pin 4 (115.8V P801 pin 2).
(3) P-DIM: controls the backlight brightness. 
Controled by Cust. Menu, Video, Backlights. 
Range 0% to 100% directly proportional to 
DC voltage to Backlight brightness. 
P-DIM is actually a PWM signal.
If P801 is disconnected, the backlight power 
P801 pin 2 will be 140V and stay there. P801 
pin 4 will be 175V and stay there.

Front IR
Note: If a particular area is exhibiting a dimmer backlight level than other areas or the 
overall brightness seems dim, be sure to first check the customer’s Menu setting for 
Backlights. Raise the percentage and see if the overall brightness returns to normal. 
If not, 
1st: Check the P-DIM level, it should rise with the percentage shown on screen. 
 100% = 3.27V. Follow the P-DIM signal all the way to the SMPS. 
2nd: Turn off Local Dimming in the Customers Menu. 
 If the brightness returns to normal, examine the signals required for Local 
 Dimming. (SIN, V-SYNC and SCLK). Suspect the Main Board.

SMPS TEST 2
PWR ON
PWR_ON Pin 1: Turns on 12V and 24V 
(Also see Note 2)
DRV_ON Pin 2: Turns on Backlights. 
(Also see Note 2) DRV_ON is INV_ON from 
Main.
Note 1: Pin 16: Is Open on the SMPS. 
The voltage is loopback from the Main board.
Note 2: Backlight power is 62.6V with 
PWR_ON arrives, (no backlights) it goes to 
84V when DRV_ON arrives, Backlights On).
Note 3: LD701 normal state is Off. If it is 
blinking, it indicates a problem. Missing 
DRV_ON, P-DIM, BL feedback error, etc….
Example: If either P801 or P802 is 
disconnected, LD701 blinks 5 times at start, 
then blinks 3 times every 5 seconds.
If DRV_ON is missing, LD701 (after 1 minute), 
blinks 5 times every 5 seconds.

SMPS TEST 1: To Force Power Supply 
On without the Main Board.
Disconnect the P2301 on the Main board.
(A) Jump pin 3 (3.5V) to pin 1. Test 
Voltage Outputs 12V, 24V to Main and 
62.6V Backlight power. Remove AC 
power. No Backlights at this time. 
During Test 1, the Error LED (after 1 
minute) begins to blink 5 times every 5 
seconds. 
SMPSTEST 2: 
(Turning on the Backlights) 
Leave 1st jumper in place. 
(B) Jump pin 5 (3.5V) to pin 2 (DRV-ON). 
Apply AC power, the Backlights should 
turn on. Note, the LED B+ will now jump to 
84V. During Test 2, the Error LED 
(immediately) begins to blink 6 times 
every 5 seconds.
If P801 or P802 is disconnected, the Backlights 
come on, on the side that is still plugged in. 
Then the go back off. Error line goes high and 
LD701 blinks 3 times every 5 seconds.

Note: If a particular area is exhibiting a dimmer backlight level than other areas 
or the overall brightness seems dim, be sure to first check the customer’s 
Menu setting for Backlights. Raise the percentage and see if the overall 
brightness returns to normal. 
If not, 
1st: Check the P-DIM level, it should rise with the percentage shown on screen. 
 100% = 3.27V. Follow the P-DIM signal all the way to the SMPS. 
2nd: Turn off Local Dimming in the Customers Menu or disconnect CN1002 and 
CN200. 
 If the brightness returns to normal, examine the signals required for Local 
 Dimming. (SIN, V-SYNC and SCLK). Suspect the Main Board.

You can also test each of the 100 blocks functionality by 
grounding the return path signal (using 220Ω resistor).

SMPS TEST 2
PWR ON
PWR_ON Pin 1: Turns on 12V and 24V. Also 12V to UHD and 24V to INV_Main.
DRV_ON Pin 2: Turns on Backlights. DRV_ON is INV_ON from Main. Routed out P202 
pin 12 to Inverter Main. Routed out P202 pin 12 to Inverter Main.
PWM_DIM Pin 4: Leaves on P202 pin 14 to Inverter Main board CN1400. P_DIM controls 
the backlight brightness. Max voltage level is set by the by the (Customer’s Menu --> 
Video --> Backlights). Range 0% to 100% directly proportional to DC voltage to Backlight

Note: If a particular area is exhibiting a dimmer backlight level than other areas or the 
overall brightness seems dim, be sure to first check the customer’s Menu setting for 
Backlights. Raise the percentage and see if the overall brightness returns to normal. 
If not, 
1st: Check the P-DIM level, it should rise with the percentage shown on screen. 
 100% = 3.27V. Follow the P-DIM signal all the way to the SMPS. 
2nd: Turn off Local Dimming in the Customers Menu. 
 If the brightness returns to normal, examine the signals required for Local 
 Dimming. (SIN, V-SYNC and SCLK). Suspect the Main Board.

SMPS TEST 2
PWR ON
PWR_ON Pin 1: Turns on 12V and 24V (Also see Note 2)
DRV_ON Pin 2: Turns on Backlights. (Also see Note 2) DRV_ON is INV_ON from Main.
Note 1: Pin 16: Is Open on the SMPS. The voltage is loopback from the Main board.
Note 2: Backlight power is 0V with PWR_ON arrives, (no backlights) it goes to 24V when 
 DRV_ON arrives, Backlights On).
Note 3: LD701 normal state is Off. If it is blinking, it indicates a problem. Missing DRV_ON, 
 LED feedback error, Controller Error, etc….
Example: If either P801 or P802 is disconnected, backlights come on, then shut off, then LD701 blinks 
3 times every 5 seconds.
If DRV_ON is missing, LD701 (after 1 minute), blinks 5 times every 5 seconds.

LED SINGLE BLOCK TEST (DIM OR DARK PICTURE AREA):
Turn the Brightness, Contrast and Backlights all the way up. Confirm 24V on TP P251.
Confirm P-DIM is approx. 3V. Using a 220Ω resistor, (one end on ground), jump any of 
the blocks grounding pins on P801 or P802 (VC1~VC12) while observing the picture and 
each block should turn on maximum. (No: Bad Panel, Yes: Bad SMPS).

Note; If there is a problem with a load from 
the panel backlights, you can remove AC and 
Disconnect either P801 or P802. When AC is 
reapplied, the Backlight LEDs should turn on 
for about 4 seconds and then shut off.

SMPS TEST 1: To Force Power Supply On without the Main Board.
Disconnect the P2301 on the Main board.
(A) Jump pin 3 (3.5V) to pin 1. Test Voltage Outputs 12V, 24V to Main, Note: 
Backlight power is 0V. Remove AC power. 
No Backlights at this time. 
During Test 1, the Error LED (after 1 minute) begins to blink 5 times every 5 
seconds. 
SMPS TEST 2: 
(Turning on the Backlights) 
Leave 1st jumper in place. 
(B) Jump pin 5 (3.5V) to pin 2 (DRV-ON). Apply AC power, the Backlights 
should turn on. Note, Backlight Power (LED B+) will be 24V. 
During Test 2, the Error LED does ot Blink.
If P801 or P802 is disconnected, the Backlights 
come on, on the side that is still plugged in. 
Then the go back off. Error line goes high and 
LD701 blinks 3 times every 5 seconds.
