Broken Display?

[skllbshr]

Ok I have a US Cellular touch pro with the latest Energy rom and lately the display has been acting weird. It'll be working fine one minute then next thing you know it'll either have a black screen (backlight still on) or a series of vertical fading vertical blue lines. It has also done the line thing with other colors cycling through them...kinda looks like an animated wallpaper. Sometimes I can get to go back to normal if I keep turning the screen on and off, but I usually have to take the battery out and reset it a few times to go back to normal. Programs still run while the screen is black, I also noticed if I hold down the power button to go to the slide2shutdown menu it sometimes fixes it...so I really can't tell if its a problem with the rom or a hardware problem. Any advice?
