820-00281-A Water damage

[vsa100]

Hi!

I have a 820-00281-A water damaged (coffee...) that is completely dead.
Inspecting the board if found slight traces of corrosion around U7660, Q640, Q650 and UB700

What you guys suggest start checking?

Thanks

Start posting some voltages.
First of all, do you get 20V indication on all USB-C ports?
What about 3V3_G3H, PPBUS_G3H, 3v3_S5?
Check for short on big coils too.

First thing to check is what voltage you get on DC-in 5 or 20 volts. Need to get a USBC ammeter if you don't have one yet
