I'm new to all this. I had to replace a digitizer on Sprint EVO 4g, after the replacement I have a white screen, and I mean white, no evo, no sprint, no htc, just solid white..Volume down/power does nothing. Pulling battery does nothing. This is just a plain phone, no root, no add on's no nothing. All I did was replace the digitizer. It was working fine before replacement, but it was cracked to bad to really be useful. Thanks for your help.
