As the previous message said, try changing the input. If you're using a singel RCA cable from your Sub out in your source component, try disconnecting that and using the speaker-level connection. Or vice-versa.
If it then works, you know you have a faulty input on the sub. If it does not work with either, the sub's amp is faulty or the wiring from the sub's amp to the woofer may have come loose - pray that this is your problem, it is easily corrected.
Good luck!
