looking for schematic for Acer SP313-51N board Yacht_TL 203022-1

Hello,

I'm looking for the schematic for a Acer board Yacht_TL 203022-1
The board had some minor liquid damage.
I have no shorts, have 3v, 5v, 3.3v, ... but no leds or power on.
When touching certain parts of the board with my finger, the powerleds go on or start blinking.

long shot, but don't know if anyone has this boardview or schematic ? Or maybe some ideas how to diagnose this board.
Touching some areas make the leds go on, but when I touch ground with the other hand, the leds go off.
What could be a cause of this ?
