My uncle gave me his old iPod classic 30gb. He said that it's charger was lost and it's been a year that he haven't use it since its battery was drained, I tried to recharge it but it only shows the apple logo for 2 secs. Then the screen turns blank again. I tried to reconnect the USB cord And same thing happened. I really wonder if it's charging or there's something wrong with it... Please help. Thank u guys in advance!!!
