laptop display not working but external monitor works

텍스트:

Hello there,

I got this laptop used from marketplace as a weekend project, after a few weeks i still couldnt find a solution

It also does not recognize (in device manager and hwinfo64) the internal display as well, only the external one.

I tried troubleshooting the gpu drivers, ram, bios, etc and nothing worked

Could it be a motherboard issue?

When i opened it i found this:
