Since this is a power sub woofer, it may have an amplifier problem that would require professional service. Yoiu can start by checking the fuse. Make sure the sub woofer is not plugged into the wall when you check it. Some of these powered sub woofers have the fuse right on the panel where the cord goes into. It may have a round cap and you turn it and pull the fuse out. If the fuse is blackend or you can see that the filiment inside the fuse it broken, you can replace the fuse with the same rating of fuse. The rating is on the metal tab at one end of the fuse or may also be listed right next to the cap for the fuse holder. If the fuse is not accesable from the panel, you need to remove panel and look for it where the power cord comes into the panel. It will be right in line with the power cord. The panel for most sub woofers are normally held on by screws all the way around the panel. You should only need to take the outside screws (around the edge of panel) off of the panel. The inside screws hold on the circuit boards, connectorsm and transformer.

If you had given more information about the problem with your sub woofer I could have given you a better answer, but with the limited information given all I can suggest right now is to check the fuse. That is always a good starting point. If you give me more information I may be able to help you much more, I have repaired many powered sub woofers but not this model. Most are very similar and can be checked with minimal effort. You would need to have a multimeter to check almost everything else with the sub woofer. Let me know if you have a multimeter and are willing to check it further. Anything less than a "FixYa!" rating is really not a good rating, so please do not rate this solution until we have had a chance to communicate more about the problem. That way I will not be given a bad rating when I have not had a chance to actually help you yet since I can not tell you how to fix your problem without more information.

My receiver doesn't have a dedicated subwoofer output, can I still hook up a subwoofer? I have a harmon kardon avr 25


That would depend mostly on your subwoofer. There are some that slave off the front left and right speaker outputs and still pass the amp's power to the Front Speakers. That would be the only way that would ensure volume control.

Otherwise you have to feed a self-powered sub from the Tape Outs but that won't allow volume control from the H-K.

I cannot determine if this is a defect with current information here is link to your manual:
http://manuals.harman.com/HK/Owner's%20Manual/AVR55%20OM4-98.pdf
go thru setup speaker process on page 21 and see if it is a setting issue. Let us know if you need more advanced troubleshooting.

Cheers!

The sub does not work it shows a signal but no sound


Try checking in the preamp/prepro setup menu that your subwoofer is enabled, then check the level in that setup. Then check the level on the subwoofer itself. If all is well then check that the subwoofer connection is in fact connected to the correct output on the pre/pro.

How do i connect my subwoofer to my tv


Have you tried connecting an AV cable from yoursuboofer to your TV?
If so, what type of connection cable does your Woofer have?

Is your subwoofer apart of a surround sound system or is a separate unit?
