Problem with screen--water damage?

view story

http://forum.xda-developers.com – So I dropped my phone on a wet floor. I wiped it off and it seemed fine. Next day, after some normal use, I turn on the screen and only the capacitive buttons turn on, not the screen itself. I hold down the power button to reset, and its still like that. The phone works and incoming calls/alarms still sound, i just have no way to answer them. Later I managed to get the screen to come on by literally smacking the phone (it filickers a bit during the smacking process). Yet after any substantial movement it goes blank again. This process repeats a few times until smacking is no longer any use. (HowTos)
