The LG mp3- JM53 8GB was working correctly when suddenly certain songs were telling me that they weren't in sync with my Mp3 player. Then next day I started the mp3 it flashed on said something about being out of sync then closed down and refused to open again. I tried recharging it, pressed the reset button and it still won't start. What is wrong with it and pleas explain it in a way that even an idoit would understand b/c I am one when it comes to electronics. Thank you for your time and help!
