You can try using paint thiner with a toothbrush and brush off the whole board (every little corner) and let it dry with a little heat) wait 3 days and it should turn on. Thats how I fixed mine. It works, but it turns off by itself every now and then.

Unfortunately no, it is beyond economical repair. Water fries the circuits immediately.
