Question about Audio & Video Receivers
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.
