Your mp3 seems to me like its defected and this is common among all MP3 players (not only ipods for you poeple). For a solution, you should try and seek for help by going to the company's website and look up their F.A.Q. on that particular mp3 player.
i just got a ilo mp3 player and it was working fine but the battery went dead, so i changed it and now everytime i try to turn it on the screen "ilo" comes on but then it turns off!!! how do you fix it?? thanks
