MODEL: MacBook Air 2018 A1932 820-01521
Problem: 5.12V / 0.60Amps
History: Unknown but I can see slight liquid spill on IC U8201/74aup1t97gm
Things tried: I've cleaned the liquid area, removed the IC U8201/check pads, good/ chip looks good, put back. Replaced CD3215C x 2 times, so 4 new chips just in case. I've attached photo readings of V/resistance and signals as per logi wiki website. Please advise what I can check next. Schematics available upon request.
