Hi try this .. cheers

This will reset the phone but possibly leave contacts, pictures on there.......

Here's the FIX: remove and replace battery, but don't power on. Hold down Volume Up, Volume Down, and Power at the same time. When Vibrant logo appears, let go of all. menu will appear. Select clear user data using Vol up/down to move and power to choose. Select yes. It'll reset sans locked screen. Now you just have to download all your apps again unless you have a recent backup.

Sounds like you need an inverter board which is the power supply for the screen lights. I tried to look up the part but samsung dosen't have a service diagram posted for it yet. Since it is so new you may want to find a samsung authorized service center because if the part is not available yet Samsung will have to solve the problem.
