Did you test the board alone on the desk?
Which components have been affected by liquid?

 

[ajdoc]

Yes, board alone

Affect areas:
UP800 (removed at the moment because there was short on PP5V_S2_MAIN
UD770, C7702, QP700, U5700, UD500, C5150, UR200, R8170, R1983, CE412, UE022

Many of the mentioned components connect with CPU; it may be damaged already.

PMU_VDDHI is correct, so U8100 should deliver steady LDOs.
Check them for voltage pulse and diode mode to ground.
Also check U7700 LDOs.

I suspect you have more corroded components, or traces; even under some BGA chips.
