Problem With Sansa C140 !!!!!!!! PLZ HELP !!!!!

well i’ve had my Sansa c140 for about 1 year. My uncle bought it for me … and now it just broke down. When i try to turn it on it goes around normally , but only for about 4-5 min and than it automatically closes. If I try to turn it on again , it won’t start. If I leave it like that for a week or so , it will turn on again but still for only 5 min. Don’t know what’s wrong and I’m not from the states so I don’t have a SanDisk store/service around me :(   BTW if I plug in the USB Cable it works … I can transfer as much music as I want.  Got any ideas ? THX !!!

Have you tried changing the battery? :smiley:
