My HK AVR65 receiver refuses to let the subwoofer go into standby mode when the receiver is shut off. While "off" the power light glows orange and the subwoofer light is green. While on and no movie is playing, the sub will go dormant and amber lights up. If I completely unplug my receiver, sub will also go into standby mode but I have not done this in the 7 years I have had my sub.

Have I damaged my sub in any way? This was a known issue with the AVR65 but everyone said not to worry about it. I also didn't want to have to unplug the receiver every time I was done watching a movie just to get the sub to go dormant.
