My reference only: REF1144

History: Board had liquid damage but I have cleaned it up.
Problem: No S5 other than when I first plug in the charger, it goes real fast, but looks like the voltage jumps up to 3v, then quickly drops. I never get anything else after that.
I have already replaced U7000, C7651, and U7650 because I was not getting 20v, but I get 20v stable every time now. U7650 I replaced just for good measure, but I got the same result.
