Hey everyone, had a A1932 come in that has no visible damage or liquid spill. Board number: 820-01521-02
It powers on, charges 20v 1.6a. CPU gets hot, trackpad reacts, but I never get an image or backlight. One strange thing is that the light of the caps lock doesn't light up although it seems to be on.
I tried:
Working display and flex
External display
DFU (doesn't recognize the device)
PPVCC_S0_CPU comes on so assuming power on sequence is good
When inspecting the board I did find solder balls popping out from under both D8410 and U4802, the diode still measures normal and no shorts on or around the ic, so no clue if it means something.
Where do I go from here? Any advice welcome!
