Touch Screen Blank But Notification Bar is displayed

[brianthehousesimpsonville]

I recently rooted my mytouch 4g(lg e379) phone using UnlockRoot. Worked fine for a few hours. I turned my phone off and turned it back on and it gets stuck at the Andriod 4g tmobile screen, but if i plug in the usb cable it will jump past the screen and the display will be blank except the Notification Bar which is functional. If i call the phone the screen lights up like a normal call then goes back black with no response when touched after the call is over. Any ideas i really don't know how to fix this issue. Thanks
