After saving up your money to buy a home theatre stereo system, the last thing you want is for part of it to stop working. Subwoofers are the part of the system which amplify deep bass notes in the movie soundtrack. Should yours stop working, there are a few simple steps you can take to either fix your subwoofer or help identify a problem for repair. Checking your home stereo should only take a few minutes.

Check the subwoofer audio connections. In some cases, many cables may be connected to the back of the subwoofer, and it only takes one to come loose to affect performance. Play a DVD and slowly unplug and reinsert each cable to see if sound is restored.
Check the power supply. Powered subwoofers will have their own plug; check to ensure it is inserted properly. Try swapping the subwoofer plug with another to eliminate the possibility of the plug being defective. Make sure the cable is properly inserted into the back of the subwoofer. If the plug is fitted with a fuse, try changing it.
Place the subwoofer away from other objects. If it rattles when in use it may be vibrating off other appliances. Try and isolate the subwoofer as much as you can or consider placing foam padding around the box. Subwoofers can often cause annoying vibrations if placed directly on wooden floors. Consider moving the subwoofer to a case or placing foam padding underneath.
Move the subwoofer as far as possible from the TV screen if you experience an electronic hum or tone. This can be caused by electrical interference from other appliances, particularly the television itself.
Give up and call a professional if problems persist. It may be that the subwoofer itself is faulty and cannot be easily fixed. Look in your phone book for electronics repair shops. Alternatively, search the Internet for repair locations. If your system is under warranty, you should contact the manufacturer to seek a repair. If not, they may be able to provide you with contact details for an authorised repair shop or repair the subwoofer at a cost.
