820-00165 PP3V3_SUS and PP3v3_S5 are both 2.8V

[No-Clean]

Board had some little corrosion around Y1905 and U6100 rest of the board is clean.

PPBUS is 8.6V
3v42 is 3.4V
PP5V_S5 is 5V

But PP3V3_SUS and PP3v3_S5 are both 2.8V already replaced U8020 and same thing.

Please advice!

Get correct 3V3_S5 first.

Inspect for corrosion near U7501; especially R7560/1/3.
You can play with R7560/1 to adjust 3V3_S5.

U7501 was replaced and same thing, R7560/1/3 no corrosion and measured ok.

Replaced R7561 with 8.1K and walla!

Muchas gracias!
