820-01700-A Not turn on

[Sawter]

Macbook does not turn on.
have
PPDCIN_G3H = 5v
PPBUS_G3H = 1.02v
Apparently there is no short to ground.

Post diode mode to ground at PPBUS_G3H (not L7030) and 3V3_G3H_RTC (L6960/61).
PPBUS_G3H is the first voltage to appear on the board.

If you get 5V at R7020, then post U7000 basic voltages; P_IN, AUX_DET, VDDA/P, EN_MVR, CBC_ON, A/BMON.

 

[Sawter]

PPBUS_G3H = 0.9V
R7020 = 5.2V
P_IN = 5,2V
AUX_DET = 1,26 V
VDDA = 5,01
VDDP = 4,90
EN_MVR = 0V
CBC_ON = BGA PARA BGA SEM PONTO DE TESTE

What about diode mode readings above requested???

 

[Sawter]

Sorry forgot.
Diode mode in PPBUS_G3H = 0.355

Try changing U7000...
