Welcome to the Apple Community.
If this is the Apple TV 1, you might try pulling all the cables for a few moments and trying again, but it may well be the unit has failed.
If its the Apple TV 2, get yourself a micro USB cable (sold separately), you can restore your Apple TV from iTunes:
Using the USB cable and iTunes to reset Apple TV has not worked for me. It is stuck on "contacting the Apple TV server" and goes no further.
