    Samsung UE55JU6050UXZG

    Hi,

    Saturday I have bought a Samsung UE55JU6050UXZG Screen which has a bad mainboard (the seller sais so).
    The Seller has tried to repair the tv at a samsung service, or other tv maintenance service and they analysed it, and told him they could do nothing for him, warranty was expired and they couldn't get a new main board.

    I removed the cover, plugged in the power supply, but without Mainboard and the backlight started working immediately.
    I made a video from my next try with mainboard, i think its better than my crappy english...

    Samsung Startup video

    Can you tell me by viewing the video which component you thing is bad?

    I already checked the capacitors on the power board, also i checked the voltages on the pins to the mainboard and they look really good.
    I was hoping (when I bought the tv), that it is just a broken capacitor or something like that, but it seems they are ok.

    I cannot check the t-con board but i think thats also ok.

    Can you tell me why the blue light on the tcon board goes of every ~30sec?

    I already ordered a used mainboard for this tv, at ebay.

    Thanks in advance
    Guido

      No backlights with the main board hooked up? And you said you have backlights without the main board hooked up. If you have a volt meter, check the BLon pin that goes from the main board to the psu. I am thinking bad main board here, since BLon is generated on the main board.

        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....

        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 – Menu scrolling by itself even after removing button board (Main Board EBU66792103)
        by ygorsan
        Hi everyone,




        I’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).







        🧩 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.

        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

        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"...
