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?
