I had just installed the Power Control widget. Was setting up an option for screen brightness and the phone immediately went dark. I turned it off/on, took out battery, etc. and I still can't see the home screen. I know the display works because I can see the Samsung and Verizon splash screens when booting up the phone. After that it just goes dark. Also, I can call it and hear the ringtone, but no display. Anyone help please? REALLY don't want to do a restore to default, but if that's my only option I will.
