    Sanyo DP50747

    This tv once turned on , makes a 1 click then another click comes on for 6 to 10 seconds shows image and sounds then shuts off. Then clicks again and shuts of in 3 sec with no image or sounds. Keeps doing this. I Did the self test with the logic board and the main board unhooked. It shows all the colors and pattern test fine. Never shuts off. So i order a main board.

    Second main board installed and it did same thing. Made one click then few seconds another click. Tv comes on with sound and video then shuts down and does the 3 sec click on and off thing.

    I'm guessing bad main boards. Just figured i would ask for some input before ordering another board.

    Self Test i did https://www.youtube.com/watch?v=IXXSdctd7Y8

          Just a follow up. Tv is working now. The only thing Self test shows is panel okay with images and stuff. Does not show if you have a problem with power board completely.

          Had to change 5 caps on power board and one on X board.

              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.
              • I

              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"...

              (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....
