Have a 820-3115 that had liquid damage. Replaced u7000 and surrounding corroded components. After doing this I had a fan spin for a few minutes. Not sure what happened but when I plug it in now I hear a small clicking sound and the green light blinks rapidly but no fan spin.

I now only have 11.82V on PPBUS_G3H

11.8 is no good must be 12.23 or 12.56. Check resistance between pins 17/18 27/28 on U7000, also check R7005.
