My MATSUI Mp3 turns itself off and on and never players?

I recently got the MATSUI mp3 player 2GB but when turned on it goes back off. i thought must be the batteries but no. even with new batteries, it does not even hold enough to play anything but turns itself off and on, nothing more. It played out this way sometime when i was listening to sound on it and it suddenly went off. now it does not even play anything as it just turns on and off, immediately and keeps doing that except the battery is removed or i switch off.
