BB Bold :: Screen Goes Black But Lights On The Keypad?

The screen goes black after the backlight comes on but the light does not return. Everything is functioning like I get notifications, I receive calls and bbm's but the thing is I can't check them because the screen is black. There is static as well at the top but it it is black and blurry, sometimes I could see the name of the service provider as well as the battery icon.What would work sometimes is if I do a battery pull but that is rare. Also if I lock the screen then wait a while and then press any button between the end call and receive it would come back on. But that is becoming rare as well. The system on the phone is full functional but its the screen that stays black.Sometimes if I'm lucky it would go away and I would be able to use the screen. But when that happens I would have to constantly be pressing a button to keep the phone active so it does not go on backlight setting from inactivity. U can imagine how annoying that is huh?
