Hi everybody,
So I have a waterdamaged unit that I don't seem to ba able to fix. When connecting the charger I draws .19A at 15.1V
At that moment two or three components start to get pretty hot and I'm unable to touch them. I tried to remove them from the circuit, but both shorted sites remained shorted.
I have replaced the BQ2, the M92 and the 13USB. Even the Max77 chip. But to no avail. I also removed the USB-C.
The shorted cap close to BQ2 is still shorted at the pads when I remove the capacitor. The same is the case with regards to the capacitor at M92. Its stil a short when I remove the capacitor.
I even used a few hours to remove the SoC, reball it and put it on again. None of the shorts dissappeard when removing the SoC.
Does anybody have any suggestions?
And there's a missing inductor on the backside, but that should not have anything to do with the shorts.
