Does it display 'boot error' message on its small screen?
OK, what happens when you hit play button?
Have you tried to format mp3 player memory then copy few mp3 files and tried to playback?
I have its firmware which is special software and you can't copy it form other mp3 player, I'm asking these questions to determine either it is firmware issue or something else.
So does mp3 player charge and display lit when connect it to computer USB?
OK, are you sure the mp3 is fully charge?
and it doesn't play when hit play button?
OK, connect it to computer, does Windows recognize it as mass storage device or as walkman device?
OK, there is a chance that it may be firmware issue or may be hardware failure and we can't know unless try to update/ overwrite firmware, so in other words, I can provide you firmware file along with instructions file that may or may not work, I need to send 'additional service offer' as per website rules to provide firmware file which would cost you additional $10, please reply back if you agree to proceed.
No, you haven't charged any thing so far as your money is still deposited with website that you can leave for any next question in future or contact customer service for refund.
