A1466 820-00165-A PPBUS_G3H no power

Hi,

I have an A1466 PPBUS_G3H witout power.

It startd to not charging the battery, and so I replaced the battery. After a while, it stoped working completly. Not even has green light in the charger.

PPBUS_G3H = 0.860V and 0.139 on diode reading.

PP3V42_G3H = 3.4V

SMC_BC_ACOK has 0.070 in diode reading.

U7100 CHGR_DCIN pin has 16V.

Can it be U7100?

No big coils seams to be shorted.

Shall I inject voltage on PPBUS_G3H?

Inject why???
You don't have short there, nor even low resistance.

Just in case, replace F7140.

Hi.

Probably my mistake, but comparing diode readng of PPBUS_G3H with other board, I get 0.545.

After replacing F7140 it powered on once, and then became the same; No green light and no power on.

Already replaced the charging port, but still no power.

00165 should get 0.120-0.150 in diode mode there.
Be sure Q7130 is the correct model.

Post exact C7098 and C7140 voltages.
