I recently moved and when I went to watch my T.V it had a kaleidoscopic of colors and the background looks white but I can't see any picture or sound due yo all the lines and different colors. There are 2 smalls cracks at the bottom of the screen when u feel it but aren't visible to the eye. I've read where it could either be the screen or panel but I really can't afford to have a professional look at it. Is there any way I can check at home and maybe repair myself? It's a 40" Proscan flatscreen tv. Any help would be greatly appreciated. Thanks
