820-00928 Short on PP3V3_S4_SOC_PMU

[No-Clean]

Clean board, at this point this is a project as it was left here abandoned and it will be nice to repair it.

Came in with a short on PP3V3_S4_SOC_PMU C4205

I get 20V and 0.040A in USB meter

After removing short PP3V3_S4_SOC_PMU is still 0V so U4200 has no output.

Is U3900 the problem you think?

PP3V3_S4_SOC_PMU comes from 3V3_S4; do you get that one?

The problem was way before that, U7650 was shorted

That means no 3V3_S5.
No idea how/why did you go for 3V3_S4 in such case...

Came in with a short on PP3V3_S4_SOC_PMU C4205, I was lost and needed some guidance, with your tip I was able to trace back the fault, thanks!
