820-02773 - liquid damage on keyboard

[tawnytim]

A2338 came in for no power, liquid damage to keyboard. Fairly heavy corrosion around JR940 and surrounding area. Cleaned all corrosion, reflowed components in that area. Now I have the board at 5.19v drawing 41ma. PP3V8AON seems to pulsate from 0v to 3.3v, as observed at L5820:2.

Where to go from here?

Water damage board is nightmare, like always.

Check diode mode to ground on all secondary power supplies.

PPBUS_AON is stable?
Tested with charged battery?
