Snowy pixels moving over the screen

My Samsung Galaxy Trend fell and now it has snowy pixels moving all over the screen. When the phone starts up the Samsung logo is displayed without the moving pixels, but at boot it starts. After boot the screen stays snowy. I can see through it, but the moving pixels are very very annoying. To me it seems a software issue as it doesnt show on boot.
