Hi, i'm sure you get alot of queries on 'faulty' mp4 players but I have an MP4 player, and it doesnt seem to work. It doesnt have a make on it, its black, slim and looks like an ipod and says 'mp4 digital player' on it. It just doesnt seem to start when i switch it on, i press play and the screen remains blank. When i put it on charge then the screens comes on the im able to play my tunes, but otherwise it doesnt start. I really hope i dont have to buy another one. Help!

Thanks

Niki
