i went to check my LG ally and when i tried to turn on the screen nothing happens, so i tried to turn off ther phone and tuern it on, nothing. i take out tthe battery and put it back in, nothing. my screen is completely black no matter what i do. i didnt do any damage to the phone so none of this makes any sense. i even tried keeping the battery out for an hour and putting it back in. the phone turns on and i can see the lights in the keyboard, but the screen stays black. is therte anything i can do to fix it?
