Hi, I have a white blackberry pearl that doesn't work. The phone turns on, but the screen is black. When someone calls me the music turns on and I can answer, but still the screen is black. I don't know what to do with it... Any advice?

First, welcome to the Forums.

You probably need to replace the LED screen, getting a new or replacement BB may be a better idea. Look at BlackBerry Repair Shop - A full line of RIM BlackBerry repair services and BlackBerry parts for all BlackBerry handheld devices for starters.
