I got my refurbished Onkyo 7100 system about a month ago and it has been working great. But, for some reason, my sub-woofer isn't working anymore. I've checked out the cable, used a different one, and no results. The light still comes in blue on the subwoofer, power is getting to it fine. But even when I go to the speaker setup to change the Level Calibration, sound comes out of each speaker as I select it...except the sub-woofer. It is turned 'on' in the settings.
What's the problem?
