820-3208-A Fan spins 5 seconds and stop

[zockysworkshop]

I have water damage 820-3208-A and i fan spins 5 seconds and stops i went thru the rails and the 5v and 3.3v in s3 state are going from 0v to their normal voltage and back to 0. On U7201 i have VIN and all enable signals and i think is the actual chip. Any ideas ?

CPU Vcore coming on?

CPU vcore goes from 0 to 1v and back to 0

This could be anything, where was the liquid damage?
Does the fan start and stop and then start again in a loop?

liquid damage around q2730 and i replaced c2231 because was hanging not soldered from the water. And yes fan goes in loop start stop start stop

Can be anything. Inspect for corrosion again. Possible under SMC/PCH
