Hi,
I have an A1990 820-01041 with no power.
It only has 5V on ampmeter and 0.01A
All CD3215 LDO and CC1/2 diode readings are normal and no big coil is shorted (includind SSD's).
PPBUS_G3H is shorted, with 0.003 in diode reading. Already removed F7000/1 and U9080 and the short remained.
I've injected 2V and have an 1A consume, but I cant see anything hot in the IR cam with the heatsink removed.
Can you help?
