Grey screen on start up
 

Newbee here. I have a HTC touch pro and I have an intermittent problem. After using text or phone and locking, the phone goes to sleep. When i tap the power button to wake I get a grey screen? Soft reset dosen't cure the problem? Pulling the battery out and replacing it doesn't help? Changing batteries with a different one doesn't help? It vibrates when it starts up and there is a glow just around the edges of the screen. Volume button works. Keyboard lights up. Just no image on the screen. Just answered a call talked for about 10 minutes ended call and screen is grey? My computer doesn't recognize when hooked up on usb? Please help. ](*,)
