Corrosion on the backlight circuit is very bad.
Leakage to data lines can easy kill T2, or CPU.

Do you put the machine in DFU with keys combination, or it automatically appears in AC2?

Check diode mode to ground on all coils; including the small ones for SSD.
Compare readings with good board.

It automatically appears in AC2. Don't have same working board at the moment to compare, but i will check them as soon as i will have one :giggle:
