    Samsung UN40J6300AFXZA Main Board Repair

    I know this Samsung UN40J6300AFXZA BN94-08247E main board is bad. Screen is black with sound and back lights but no picture. I replaced the T-Con board with no change. I cannot find schematics for this board. Bought a similar main board for a different Samsung TV thinking I could just swap out the flash/eeprom chips. I swapped eeprom chip but replacement board show no signs of life. Should I swap out eemc chip or could the problem be in the SDP1415 SOC? Any help or advice is greatly appreciated.

    Original Board: BN94-08247E
    Code: BN41 -02353A
    Mode: BN41 - 02353

    Replacement Board: BN41-02353A
    Code: BN41 -02353A
    Mode: BN41 - 02353

    Did you check the LVDS on the main board with on an oscilloscope? voltage checks on panel power etc?

      I seem to have all the proper voltages and I did check LVDS with my oscilloscope and there is no signals from main board to T-Con. I was thinking maybe the SDP1415 SOC may have a few balls that has lifted or is partially faulty.

        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.

        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.

        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"...
