          Yes this is an android based system.
          It was Diagnosed by a repair center in Tucson who explained that they thought it was the main processor.
          Their term was a corrupted processor.

          They were unable to get a replacement processor for the repair. ( also they the repair center had not replaced this item before as well)
          The original failure mode was ( set was stuck in boot mode then detiorated to no pilot)

          Anyway I finally found a replacement board yesterday so crisis averted.
          Thank You for the response

              Hello,
              My KDL-75W850C looks like it has processor issues, It boots to Sony Logo, then powers down, and doing the 3 blinking red lights
              Can someone confirm that that would be the 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"...

                      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.

                      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.
                      • I

                      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....
