So I bought myself a Digi cam

( Olympus FE-170) Nothing too great, but just what i need... I bought it the day after Tanksgiving, so it's still new-ish... well i took it down to UofI with me last weekend, and it worked PERFECTLY... I took the pictures off of it on Sat night when I got home and left it here... I turn it on Sunday night when I got home from work... and the screen is all white!?!?!?!? Nothing happened to it, at all... it wasn't dropped, there was no water... nothing...
what could cause this??? and how can i get it fixed???
(oh, there is a time restriction... I'm going to San Diego next weekend to see my boyfriend and I REALLY REALLY REALLY want my cam for that... )
Ideas??? PAWEESE!
