Hey guys,
machine was untouched. No liquid damage. Found a short on PP3V3_S2.
UF600 was the bad guys. Replaced. Short is gone. UF500 was not functioning. Replaced same donor board, same code termination (B13). Now good diode mode readings on: RH002, RH003, RF329, RF328.
Left usbc port...
got it. UP700 was the bad guy.
but now i got the apple logo - starting to boot, then shuts off. clicking sound somewhere on the board. whats that?
when macbook tries to boot, the green led for the cam was always on and flickering. removed LP610, no light, but same behaviour.
