Ps vita was peed on by dog, any hope for repair?

Basically, I'm trying to buy a dead vita in hopes that I can repair it since the seller is letting it go for $10.

They are getting no power, no display, and no charging. Cosmetics appear to be fine.

It was likely attempted to be powered on while wet so my expectations are pretty low on the recoverability of this unit.

I was thinking of giving it an alcohol bath after disassembling it but I think that its far too late for that since I don't know how long ago the vita was peed on. Probably has shorted components already.

I can get a full motherboard replacement for $30.
