turning on only briefly, + unrecognisable characters

I’ve tried resetting the player, which allows it to be turned on for a few seconds but no more. During that time, if it’s plugged into the computer, it’s recognised but then once it turns off the computer sees it as unplugged. Also, when it’s on, the characters are unrecognisable - some Chinese, some other symbols. It flicks through a few songs before turning off. It leaves no time to change any settings. Any advice would be great. Thanks.

If it’s still under warranty (which it should be) I’d contact SanDisk for a replacement.
