820-00239 short on ppubs_g3h

[TBFix]

I have a board here that had a small amount of liquid spill around J8500 . There is a short on F7000. I lifted F7000 and the short is on point 2 of the fuse the opposite side to the U7000 is fine.
Found U7210 to be short , replaced .
Board now drawing 20v 270ma with no voltage on L7210,L7220.
L7270 has 1.05v (PPVCCSA_S0_CPU) , cpu is heating up .
I tried replacing U7100 but still the same.

Any ideas welcome

CPU got overvoltage when U7210 was shorted on its high-side MOSFET.
Very likely is dead now...

Any way to tell 100% ?. Voltages seem to be present except for PP3V3_S4SW_SNS 0v and Cpu voltages.
L7220 is reading 4ohms to ground, L7210 is 5 ohms,L7410 8ohms.

Unfortunately, this is not an exact science .
No way to assure if CPU was letal damaged.
But your CPU received 100% an overvoltage there.
