White screen - no other display!

[dfb]

Today when I finished a phone call, the screen on my HTC Apache (Verizon) turned white and it's been white ever since. I've tried soft reset, hard reset, even installing a new ROM.

Does anybody have any ideas on what the problem might be & how to fix it?

I didn't drop the phone or anything and it has worked great up until now. When I get out the stylus and touch the screen it sounds like Windows is responding properly (i.e. I tapped in the upper left corner and heard the click for when I click on the Start button).

Thanks in advance for any help/advice!
