No liquid damage or anything unusual.
It was sucking around 0.2A. Changed U2. After that 0.6-0.7A. Still wont turn on.
Measured important power rails that go in and out of PMIC. Most of them are okay, except:
PPCPU is 0.5v instead of 1v
PP_GPU_SRAM is only 0.15V
PPGPU is missing. I did measure short to ground in diode mode and it is very low 0.015.
So what should I do? My idea was to get off the caps one by one in PPGPU rail and see when is the short gone....
Any better advice?
