I am new to mac repair, trying to drive right into some of my dead macs laying around.
I have a a1708/820-00840 board that pulled 20v/.02amps. Had a short to ground on PPBUS_G3H. Removed F7000 to confirm it was PBUS_G3H, which it was. Nothing looked bad so injected 12 volts into F7000 PBUS_G3H pad, which lit up Q7680. Pads P3V3S5_VSW were all short to ground so I removed L7690 which cleared those shorts but I am still short to ground on L7690 on pin 1. I am scared to inject this line with dcps beacuse it has lines to the U0500.
Thanks.
