Not much liquid residue on the board. Seems like came in most near display control connector of course.
Some noticeable stuff in near u7100 at r7100, c7100. on other side of board around one side of u7220. Customer noted display started discoloring in one corner before it was shut down.
PPBUS G3H is 13V
ALL_SYS_PWRGD - 0V
PP5V_S4 shows voltage going to zero. Diode here to ground is .295V
From what I've seen here in forums this board CPU often gets overvoltage w/liquid damage. I don't want to waste a lot of time on this as it if it is low probability fix.
SOme quick things to check?
