Then the problem is not related with mentioned MOSFETs.
The discharge circuit can cause such problem, but in the first seconds/minutes; before the controlled power rails are not completely discharged.

What do you suggest to fix that or is this kind of problem not fixable? The mentioned mosfet areas had no liquid damage

This is annoying.
How can DFU make working machine unresponsive?
Apple doesn't care at all about clients.

SSD voltages come on?
Also check other G3S voltages...
