Sounds like you have a broken LCD screen. Go to your carrier, they might replace the phone for you altogether for free or at a discounted rate. If they refuse,the only way to get it up and running again is to open your blackberry to physically replace the LCD. If you want somebody else to do it for you go to Blackberry Repair. If you want to do it yourself, here is a Blackberry curve Repair Guide that shows how, the part is available on Ebay.
