Check voltage on the big coils.
See what voltages you get on the board.

Test the board alone on the desk; nothing connected, apart of charger.

So the board doesn't power on, is stuck on S5.

Which areas have been affected by liquid spill?
Check diode mode to ground on all big coils; even the SSD coils (smaller than the rest).
