As I found somewhere on the internet; there are two 470uF/25V capacitors on the power supply board in the sub-woofer that are the cause of buzzing, crackling and then eventually no sound. Go to Radio Shack and buy two Catalog #: 272-1030 470uF/35V capacitors and change them out. They are in the middle of the Power Supply PCB and are close to the long flat aluminum heatsink. Make sure you match the polarity properly when replacing. Your unit will be as good as new and will probably last forever now.

I have a similar problem when it is turned on, there is no sound then a buzz, then when that is finished I switch input from DVD, then back to AUX, or TV and it works. It will probably go out all together soon, but so far, I leave it on all the time because the time it takes for the buzz to stop is getting longer.
