I am unable to find the EEPROM Chip on my mobo.

Yes, they have some differences but I tried anyway.
For istance:- At byte 24: 0xBA (AliExpress) vs 0xB9 (LG original);
- At byte 20482: 0xEC vs 0xD6;
- At byte 20485: 0xA3 vs 0xAA;
- At byte 20490: 0x85 vs 0x94;
- and many others.

Problem LG 49UB850V (Mainboard: EAX65684604 / EBT62954607)

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:- I bought another
