    Sony xbr-65x900c main board 7 blinks

    I've got a Sony XBR65X900C that is shutting down after about 30 seconds with a 7 error blink code. I do see there is a temp error in the service menu before it shuts down. I have replaced IC1400 which the manual says is the temp sensor with another sensor off a parts board. After that didn't work I removed the HDMI switch IC suspecting it to be bad. Still same issue with it removed. What else is on that I2C line that could be causing this? CPU? Nothing feels hot. Still waiting on my thermal camera to arrive that *might* be of use here.

    Any ideas on further getting this board to work? Got plenty of parts boards so swapping out ICs isn't an issue.

      Sony xbr-65x900c main board issues?
      by jb_Bak
      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"...

      Sceptre U550CV-UMR 4K LED, Bad Caps on Main Power Board?
      by Dani_2024
      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...

      LG 55NANO77SRA TV ā€“ Menu scrolling by itself even after removing button board (Main Board EBU66792103)
      by ygorsan
      Hi everyone,




      Iā€™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).







      šŸ§© 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.

      (SOLVED) - ONN 100012588 No Power, Then Rebooting After Main Board Change

      ONN 100012588
      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
