My previous charger for it broke. so i cudnt charge it for about 5 weeks.It was complety dead. but now i bought a new 1 charged it all night. i came home nd it said it was still connecting.but it was fully charged on the screen. so i take it out try to turn it on. it only shows me the welcome screen. then turns of. usually it connects o my libary. but now it doesnt. now evrytime i charge it, it say connecting, conecting, connecting, without actually connecting. To sum it up when i try to turn it on it shows me the blue walkman screen then turns of. Then wen its charging it say connecting only, without connecting. HELP PLEAAAASSSSSEEEEE. Greatlly appreciated
