2019 MacBook Pro 15”. Liquid spill. 5v, no draw. PPBUS_G3H low resistance to ground, in dead short to CPU coils. Shot CPU mosfet. CPU was not shorted, standard low resistance to ground. That gave me hope. Did not inject any voltage at all, lifted CPU coils one by one, found shorted mosfet, replaced it from donor and MacBook is back in business.
Not all shot CPU mosfets will result in shot CPU!

2017 MacBook Air. Board number 820-00165. Someone was here before. Slight liquid damage or leftover residue from previous repair attempt, not sure. All voltages pulsing every 5sec. Checked SPI Resistors - all fine, tried EFI chip from donor - no luck. After another visual inspection area around R1275 had some residue and R1275 was not reading properly at the pads (from top it looked and tested fine). Replaced it and we are back in business.

A1932 MacBook Air. Intermittent keyboard caused by some corrosion on the keyboard circuitry

820-00165. SMC_RESET_L was 0.1V with all other voltages present on U5110. Replaced it 2 times from different donor boards, same issue. Replaced SMC - same thing. Started comparing resistance on smc_reset line with another board I had, it was 3kOhm, suppose to be around 250k on a good board. Removed U5110 and it measured fine. Put a 3rd U5110 and we are back in business. Definitely did not expect 2 bad U5110 in a row.

Aftermarket USB-C charger killed the USB3 switch on 2017 A1708 MacBook Pro. Burn went couple layers into the logicboard. Had to reconstruct that pad from the VIA.

820-00840 had several issues after liquid damage. Replaced one cd3215, pmic u7800 and was getting intermittent 5v_s5 and 3v3_s5. Turned out to be U7890 gate that had PP3V3_G3H pin corroded inside of it. Replaced it with another one and its all good now.
