Motorola E815 / E816 Hollywood

I don't know whats wrong with my phone. 😕 Sometimes my back light will not be on. My phone would be blacked out, but the buttons are lit up. I tried to edit the back light settings and that didn't help. I also tried turning the phone on and off, this didn't work either. As of now i cant do anything with my e815 because i cant see the screen. If you have any idea on what i should do, could u PLEASE email me or reply... Thank you in advance!
