Board had some light liquid damage, nothing serious, just one bad looking cap that I removed (from PPBUS_G3H to ground), near speaker amps.
There was no corrosion as such, just few tiny spots, really minor.
The board is stuck at 5V, it draws 0.1A all the time. Only at poweron the amperage surges up to about 0.15-0.18A, then it settles at 0.1A.
I put it in DFU and it didn't do anything, wasn't detected on other machine.
Voltages all seem OK near the CD3217 chips, all LDOs are present, also no liquid damage was nowhere around those.
But measuring other voltages, all of them were present when I checked the PP5V_S2 which is missing.
PPBUS_G3H is 12.3V, PP3V8_AON is 3.8V,...
So this is about what I checked, but don't know what to check next. I am not sure if the problem is with USB-C detection or it might be with CPU or something completely else
