Panasonic Lumix DMC-FP2 Problem

Hello, i've got a white screen with blue stripes on my Lumix DMC - FP2.
I've purchased it back in '2010, so the warranty is long gone.

Apparently unplugging the USB cable causes the screen to go white?
The camera still works perfectly fine, it's just that I can't see what i'm taking.

Is there a way to fix this problem? or Should I just replace it?
