Hi, my Nokia 6300 powers on, the screen is lit but black. I've tried changing the lcd screen for a new one with no success, I've also cleaned inside with a cotton bud, fully charged it, taken the sim and battery out etc etc. I don't think it will be accepted under warranty as they will say it was dropped however the phone still looks fine? I think the phone may have been dropped when I lent it to somebody-Grrr. I can still receive and make calls, the vibration isn't working properly either and sort of clicks. Any helpful comments about what else to try really appreciated!
