Good afternoon, this Mac suffered oxidation in region 7655, 8FHXTW and conector FPC LCD, where components were missing, I performed the replacement, in tests the Mac takes a while to present image, and after a while the image is distorted, cracked.

PPBUS 12.65V

Do you mean corrosion around Q7065?
Does it charge and works with battery alone?

Internal LCD image is good, only has external video problems?

Pretty hopeless project.
Damaged LCD connector by liquid is almost sure bad CPU.
iGPU eDP outputs directly connected to J8500.
