I have a Sansa San disk Mp3 player and it won't turn on. For a minute it turned on and everything was fine, but now the blue light comes on the ring but that's it. The screen is black. Before I could just press on the screen a little bit and it would come back to normal. But now it just won't act right. I wanted to know if you had any ideas on what might be wrong with it, or how I can fix it.

Replace batteries?
