Hello.
I have this 820-3115-A.
Initially turns on for 3 seconds and then off. Had a lot of liquid damage around and under U1800. I protected U1800, added flux and reflowed the area and cleaned with ultrasonic cleaner.
Then the board had the same issue and I noticed that U7000 was getting a little hot (noticed it with thermal camera) so I replaced it, after that PP3V42_G3H went to 4V so replaced R7021 and R7022 and PP3V42_G3H is ok again but no green light and no attempt to turn on, just takes 37mA.
I reflowed the SMC and no change.
Any suggestion?
Thanks!!
