      It is your lucky day. I have this exact board and have the exact same problem with the 2 second logo, reboot, over and over. As you discovered, the code in U108 is likely corrupt.

      I ordered a replacement off ebay, but it didn't fix the problem. However, I may have gotten a bad part so I'm willing to try again.

      While I have no schematic, I can ohm out the IC using my multimeter. Which pins did you lift?

          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:
