I'd been listening to my relatively new iPod Classic 160GB for awhile, walked over to the dock to look at the display

I'd been listening to my iPod Classic 160GB for awhile, & walked over to the dock to identify the song that had just played. When I touched the click wheel to make the screen illuminate, it just went dead. It is a new iPod, purchased over eBay from a vendor in China, and had been performing normally. I have used it only infrequently since I got it, less than a year ago. The dock that I use also keeps the iPod battery charged.

How can I bring my iPod Classic 160GB back to life? It's not frozen; it is "dead." I've tried recharging it, & tried holding the center button & menu for several seconds, but nothing happens. The screen remains black.

HELP, Please!
