    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...

    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...

    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....

    Compatibility of main boards between different variations of samsung MU6100
    by JSin21
    Hoping someone here could possibly help. I have a few questions in regards to compatibility with main boards. But I'll give a quick short run down on what's going on first;

    I have Samsung Smart TV UA65MU6100WXXY version DA01

    Now years ago it started intermittently playing up after a lighting strike. Lighting hit the block of units i was living in at the time. Ever since that night the TV started having a mind of its own, It would randomly turn itself off or on, and all inputs stopped responding like HDMI, aerial, but USB still worked. Anyway, over the next few months...

    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"...
