      I do hear a faint on and off high pitched sound coming from this part.

        That may be because the main board is not sending steady ps_on signal to power up the power supply, also not sending Inverter on either.If you check the Inverter on now it probably shows < 1VDC.
        It is getting late so that is for me for today.

              Help Needed: Samsung UE55MU8000 Dead - Possible Main Board Issue
              by Asraf Atb
              Hi everyone,

              Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.

              Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.

              I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue....

              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...

              Samsung UE65RU7090UXZT main board issue no video out. BN94-14180M
              by alltvrepairs
              Hi,

              I have confirmed that I have a mainboard problem.
              I have tracked no hardware issued on board so might be a software dump required.

              I have searched a bit but wasn't able to find anything for my screen:

              Here are some more details:
              Panel: cy-nn065hgev1h
              Main: BN94-14180M P08F

              Your help much appreciated!

              Samsung UN75RU8000FXZA bad main board?
              by Lee M.
              When plugged in it will click and cycle the BL on and off, no pic and does not respond to remote. When I disconnect the cable from the PS board to the main board and then plug it in the BL will come on and stay on. There are only two boards in this set, the LVDS cables from the panel driver boards connect directly to the main board. Since the BL comes on and stays on I'm thinking the PS board is ok and the problem is on the main board. Should I order another main board or do I need to do more testing? thanks, Lee

              Is it possible to upgrade from a Vestel 17MB97 main board to a 17MB110 Main board?
              by cheeky2
              I suppose the real question is whether the existing pinouts from ether a 17IPS71 psu are cross compatible with a 17IPS12 psu? If they are then the exchange of the main boards should have no issues providing the screen is compatible with both main boards. Obviously you can change the screen configurations easily enough (providing you have the correct files) for the main board. Why may you ask would I do this? Well a lot of the smart features are no longer working on a Hitachi 48HBT62U main board I wish to give it a new lease of life!
              Obviously the same LVDS connector for the screen connection...
