What about PPBUS_G3H and 3V3_G3H_RTC?

Hi. Sorry for late response. PPBUS_G3H and 3V3_G3H_RTC are missing. What is next? Thanks.

PPBUS_G3H is the "mother" of all voltages!
So need to fix that.
Check diode mode to ground on it and all secondary power rails.

Just in case, disconnect F7000/1 and check C7050 voltage.
