MP4 player white screen

Hello,
So I have a MP4 (Music Player 4) and it was working perfectly fine.I've had it for less than a year.So one day i'm out and it as working.Then all of a suddon i turn it off and try turn it back on but the screen just goes white.I can play music but i can't see anything.
Anyone know a way to fix it? Or should i just buy a new one? Also there is no reset button on it
