Hey Guys.

A previous repair liquid damage was working for some time and randomly would power on or not... 820-00165 A1466 no green light no power...

PP3V42_G3H - 3.4
PPDCIN_G3H - 15v
PP3V3_S5 - 0.29v

What about PPBUS_G3H voltage?
Also check SMC_RSMRST_L and SMC_PM_G2_EN.

PPBUS voltage?

 

[zcinciev]

Hi

PPBUS_G3H 8.2v
SMC_RESET_L 3.3v
SMC_PM_G2_EN no voltage

Looks like SMC issue.
Reball it as first stept.
If no result, change SMC.
However test 3V42 presence around SMC.

3v42 is present around SMC. There was some liquid damage in the area i renewed everything last time but maybe something under the SMC

8.2 is too low should be 8.6. Reflow SMC. If no change, replace from an identical 820-00165 donor board.
