Re: 37PFL5604 Main board PLHL-T845A cap layout
Who took 'em out!?
Are you sure that on that version in that set--that its supposed to have caps in those positions?
--Has the obvious flow-soldering of the pads been disturbed?
Quite often a maker will use a PSU in multiple models and there'll be considerable differences in some cases as to what caps/other parts are installed on a bare board.TELEFIX

Looking at the circuit, I would say 25V either 470uF or 680uF @ 105C.Comment

Yes they have definitely been removed as its visual and comparing it to pics of the boards for sale but I can't make the values out on the picturesComment

Re: 37PFL5604 Main board PLHL-T845A cap layout
Ok I've put the caps in and now I'm getting a blinking led code of 18 blinks. And then I get some horizontal lines appear on the top of screen and over time more will appear and disappear. The tcon is built into the main board and when I remove one side of the lvds cable then that side of the screen goes white and the other side is grey with the backlight on. Does anyone have any ideas? We are thinking it's the main board but can't even see one of them for sale in the uk. Any thoughts would be greatly appreciatedComment

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,
Iām 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).
š§© 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.... -
Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...
