diode 0.465 0 volts
So power on sequence is not even started; you can't expect any secondary voltage!
Check U7800 (7 OF 10) LDOs, at page 60.
Be sure R7835 is good.

PP3V3_LDO3V: 3.290V
PP5V_LDO5V:5.000V
I get back those voltages U7800 was bad giving me both 0 volts, still PMIC_EN_P3V3S5 missing

"SMC_PM_G2_EN comes high?"
