Not sure if you already tried to remove the battery to reset the BB. You also want to try to reload the OS by using your Blackberry Desktop software. now what I read earlier, while researching another question, was that there is the possibility of a shortening out of some pins. Check [http://forums.pinstack.com/f76/guide_white_screen_of_death-65540/|on here] even so it is for a Curve, it still applies to your phone as well. Hope this helps and gets you started.
