Hi guys and thanks for accepting me in your community. Firstly I want to say that I've never done any repairs on TVs , but I have basic electronic knowledge. So the thing is that my tv main board failed and I've found the same board but from a 32” screen. Tv powers up now but I don't have image on screen (backlight is on) . The 32” board connects directly to the tcon board but mine connects to other and then the tcon. I'll post photos later. I'm not sure if this is a firmware problem or hardware. However , I can connect the one cable straight from mb to tcon and get distorted image so I can see what I'm doing. I'll post pics on the second post. Thank you

Re: Philips 37pfl9632d/10 no image after main board replacment
possible that you need to enter the correct display code ?
you can find that 3 digit code on the back,
you can change the code by entering 062598 followed by the code, then the tv will turn of and the code is changedComment

Only 062598 followed by the code is not enough, you must use 062598-MENU-XXX where XXX is the 3 digit number you can find on the rear.Comment

Re: Philips 37pfl9632d/10 no image after main board replacment
Guys , I've bought another working dfi panel from 37pfl9732/10d , because my reball was unsuccessful and I can't make it work. I have found all the display diversity codes for that model and tried them all. When I disconnect the pcb lvds cable, tv boots , but when I connect it to the dfi ot goes into protection. Any advices? I can add the service manual if needed. Thanks in advance!Comment

hello everyone,
I don't normally do tv repairs but this is a case with my personal TV which got fried together with many other electronics in my house after a thunderstorm.
The TV is a Philips 65PUS8518/12 which had no power. I measured and concluded that the main board was probably fried through ethernet or hdmi. I found a board with same number 715GD328-M0F-B00-005Y (I had G) but from a 55PUS8518. The TV starts but the image is doubled, distorted. I need to set the panel code which is 016 according to the sticker on the back but I can not seem to do it.

Hi and thanks in advance for any input you might provide!
I have a Sceptre U550CV-UMRD8POTV83BB 4K LED (this is a dumb tv) that I bought new in August 2021, so It's just completed 3 years.
Main power board model: TP.MS3683.PC821 T-Con board: N4TP546UHDPU2L_BO
Last Sunday I was watching a dvd and fell asleep for about half hour, when I awoke the tv screen was black and couldn't get the dvd menu to show, so I changed the input to antenna and had sound but no picture, turned it off. I then got online and found this great site! ....read many troubleshooting tips and this... -
Hi everyone,
I’m looking for help with a persistent issue on an LG TV model 55NANO77SRA, which uses the main board EBU66792103 (also used in LG UQ80 and NANO75/NANO80 series).
🧩 Problem Summary:- The TV keeps scrolling through the menu or selecting items by itself.
- I removed the physical button board (the entire panel with power and volume buttons) and also disconnected the flat cable (CN202) from the main board.
- The remote control is not in use (batteries removed), and the TV still shows the same behavior.

Hey guys great forum glad to have found it. I bought a Sony XBR 65X900C cheaply because it didn't work. No signs of life at all not even a light/led. All I hear is a brief high voltage sound when I throw the power to it.
Didn't see any obvious signs of damage so right away started checking voltages. This is what I see:
Power Board Connector that goes to Main board
CN6401
Pin 01 NC
Pin 02 NC
Pin 03 "BL_ON": 0V
Pin 04 "N/C"
Pin 05 "STBY 3.3V": 3.5V
Pin 06 "GND": N/C
Pin 07 "AC_OFF"... -

Issue: No Power, Then Rebooting After Main Board Change
Short answer: replace main board and power board
Technical answer: replace main board and Q306 & Q307 on power board.
Long answer:
TV wouldn't turn on. Power switch was fine which means the main board isn't processing the power on signal. Replaced main board. TV turns on now but randomly reboots. Bad main board? EEPROM? Tried to pull main board and got a shock touching the corner of the board. That's weird. C334 (450V 10uf) capacitor is still holding a high charge....
