Screen problem??

Question

Hello can anyone help? My camera turns on just fine and takes pics fine. Tonight while turning on my camera the screen is all white with some black lines through it.. and a leaf looking thing which is black. I see NO PICTURE at all. But when i take pictures and upload them to the computer the pics still work. But when i take the actual pictures or try to view any all i have is the white screen what can i do to fix this?
