I need help on these please.
I got this Mac with no power, dead.
There was a bad corrosion on the one of the CD3217 (UF400)
All the pins from USBC0_CC2, USBC0_CC1 and UPC0_R_OSC was welded and a whole on the board.
I have rebuild the tracks and soldered a CD3217 from a M1 air.
I replaced U5200 with a good working one. Just in case.
It is now stuck on 5V.
LDO regulators that output ~3.3V and ~1.5V are present.
F5200 - PPBUS_AON - 12V
PP1V25_S2 - 1.22V
PP3V3_S2_UPC - 3.29V
PP1V8_S2 - 1.8V
USBC0_3V3LDO_EN - 1.8V
UPC0_SS - 0V
PPVBUS_USBC0 - 5.16V
