Liquid damaged board for MBP 13" A1502, plugged into charger, I get a green, then orange light, no fan spin. I measured the following:
PPBUS_G3H: 12.58
PP3V42_G3H: 3.42
PP5v_S5: 0
PP5v_S0: 0
PP3V3_S3: 0
PP3V3_S0: 0
Corrosion/build-up was around U7501 and Q7155. Cleaned up in ultrasonic, but still get the same measurements above. Can anyone help troubleshoot the U7501 circuit - I'm convinced the issue is here somewhere.
