I have same issue on Acer Nitro 5 AN515-55-75NB
Motherboard GH51M LA-K862P REV 1A

MB was shorted, so I changed 2 shorted mosfet (PQB11 and PQZ1).
Now power button work (turn on and turn off), lights up, keyboard lights, fun spinning normal with 1.40 Ah absorption and every voltages are good on every coils.
No display, no caps lock (when i press caps lock it not change, seems blocked).
Obviously I cleared and reseated memory RAM stick and tried on external monitor by HDMI.
I flashed three BIOS downloaded from this site but without success, maybe these files are not good for my MB model, so I attached my BIOS file and this is serial number: NHQB2ET00A1100CBC43400

Thanks in advance,
FabyJ

Hi hoaca388 and thanks for files!
First I flashed BIOS with TL866A, as this minipro not detect XMC chip model so I selected W25Q128FV chip model disabling Check ID but same issue.
Then I flashed EC, when MB start keyboard light colour has changed, now is white, before flashing EC was red and absorption increased up to 1.56 Ah, when close display absorption decrease to 1.25 Ah but same issue, no video
Maybe TL866A is not good?
Or something is wrong on MB?
