I have a KSW 100 subwoofer that I purchased a few years back that has worked great up until a few days ago. Now when I play a movie on my home theater system the subwoofer does not power up. As a result, I don't get any bass when watching a movie through my home theater system. Even when I flip the power toggle switch on the subwoofer from Off to On it still does not turn on. Usually when it would power on and receive a signal from my amplifier there was a green light that would light up. In a standby mode the status light would be red. The light no longer lights up at all. The power cord is plugged in properly and the fuse on the subwoofer does not look burned out. I'm not sure what else to check. I don't use it that often so that is why I'm puzzled that it won't power on at all. Any ideas?
