    Samsung 32" 37" whatever uses 'Bordeaux Plus' Mainboard

    For reference,--

    Dead initially, then crackling from speaker, then lots of vertical green lines, changing to actually working but has cogging/raggedy verticals of any displayed vertical lines, including sides of menu boxes/letters etc. This all happens within about a minute or two, but the raggedy verticals remain.

    Change the 6 100uF 16V surface-mount caps just adjacent to the power-plug on the Mainboard.
    --No need to change the 82uF--Its a Polymer cap and usually OK

    Then remove the larger of the two tin-work covers on the board, and replace the two 1000uF 10V surface-mount caps near the large surface-mount chips.
    --Cant miss 'em, Only two 1000's live inside the tin-work. Take care to replace the tin-work with its dead-toad pads correctly,--It acts as a heatsink for those two processor-chips inside.


    --Job done.

    Dell Latitude 7420 - Touchscreen not working since Mainboard replacement
    by Mirenia
    Hi everyone,

    I've got a little "problem child": my Dell Latitude 7420 2-in-1, which had a faulty mainboard.
    I replaced it, but ever since, the touchscreen no longer works — and honestly, I’m running out of ideas…

    In Windows Device Manager, I just see an I2C HID Device with error code 10. Sporadically, the touchscreen is recognized correctly for just a few seconds, but I haven’t been able to determine under which circumstances this happens.

    The touchscreen also doesn’t work in UEFI/BIOS, although it’s enabled...

    MASTER TL240 and new mainboard LW36BKC01
    by orcic
    Hello,
    I have an old MASTER TL-240 LED TV. Since it stopped working and it had a DVB-T receiver that is being dismissed in Italy, I've decided to replace the mainboard with a DVB-T2 one.
    The original problem was that when switching on the TV, the power LED was transitioning from red to steady blue, without showing video or audio.
    After checking some voltages on the power supply board (HKL-240101-B Rev. 1.4, HKL from now on) someone suggested me to replace the mainboard.
    Now I have some doubts about how to connect the new mainboard to the old power supply.
    First of...

    Vizio M43-C1 - How closely do I need to match the mainboard number?
    by Devonavar
    I have a Vizio M43-C1 stuck in a reboot loop with no backlight.

    I've tested all the voltage rails coming out of the power supply and they are "normal" for this model (PS_ON & DIM go high when turned on, BL_ON & 3D_ON are close to zero due to backlight power flowing through the mainboard, 5VSB is 5V, and 12V is 19V, which is apparently normal for this board).

    Basically, I get similar results to Garry in this post: https://www.badcaps.net/forum/showthread.php?t=80346

    So, I've ruled out the PSU for now.

    The reboot loop...

    Problem LG 49UB850V (Mainboard: EAX65684604 / EBT62954607)
    by Malva
    Hi everyone,
    I'm trying to repair my LG 49UB850V TV (WebOS 1.0, UHD model from 2014).
    Mainboard model: EAX65684604
    PCB marking: EBT62954607
    SPI chip: Winbond W25X20CLNIG Problem description:


    Originally, the TV would turn on (backlight and LED OK if I force them on), but it shut down as soon as any input was received from the IR sensor or remote. The backlight and power board were working fine.

    After testing and verifying the voltages (DRY ON, PWR ON, 12V/24V rails), I suspected a corrupted SPI firmware. What I tried so far:

    QN65QN90A - Mainboard MLCC failed - now bootloop
    by l0lhaxz1
    Hi

    I have a QN65QN90A which was purchased around launch I guess making it about 1.5-2 years old... had been working fine until a few days ago, simply went black and would no longer turn on (at all). No standby light and no typical PSU relay click etc. Absolutely dead.

    Pulled it apart without doing much research first, suspecting the power supply as it had a faint buzz (I guess due to the forthcoming found short), investigated PSU for some time and concluded there was no fault that I could spot with the board removed.

    Came to learn after a bit more research...
