I've had this phone for two years, and just recently started having problems with it. It started with the backlight flickering when i'd use the phone. It was annoying, but I was still able to use the phone so it wasn't a big deal. Now, I can't get the backlight to come on at all. The backlight for the numbers works, but the one for the screen does not. I can't use the phone at all now because I can't see what i'm doing. I don't have insurance on it, and at this point getting a new phone isn't really an option. Is there anything I can do to fix it?
