Most likely the amp in the sub has blown. It will need repair or replacement. I'd take it to an expert in repairing amps, it's not a job for you unless you're experienced in troubleshooting these things.

Wire what exactly. Which set of KLH speakers have you got?

You can't, unfortunately. Bizarrely, the system doesn't have any inputs, only outputs. There's no way to get a signal from the TV into the system. There's plenty of Amazon reviews calling this cheap junk. I'd be forced to agree.

Yes, probably, if you aren't capable of repair yourself. However, IMHO, a replacement will probably cost less in the long run. I have a KLH passive subwoofer myself. I wouldn't pay for any repair if it failed. Replacements are far too inexpensive.

Try new cables.Connect a different speaker at low volume to confirm there is no power.My first guess is that your amp needs help.

Yes... At best it may be just a loose mechanical fixing component or foriegn object :)

It could be just a lead, check your lead heads and inserts are clean. Check along your leads and wires for any obvious kinks / tight bends / cuts / nicks / something sitting down on it or any damage to the wires. It could be there is another electrical device nearby interfering at a electromagnetic level. It could be just the dials / knobs need taking off and cleaning in behind. the pickups, you may not need to remove them just spray with electronic cleaner this stuff is great for lots of different electrical cleaning problems. Good luck
