I have... Mission 700 ASi Subwoofer Onkyo TX-DS 787 Receiver Here are the facts. The subwoofer worked fine for over a year I unplugged it for approximately 3-4 months while building a new entertainment center. During this time, it sat in my closet. It was well-taken care of. I plugged it in the other day and it does not work I have reset my Receiver. ( I had a similar problem when I first got the subwoofer- the receiver wasn't sending any info to the subwoofer and therefor, no sound) DID A HARD RESET (hold down V1 and pushed Rec Out) I tried a different subwoofer cable. No change. I tried the speaker level inputs. No change. There is a light on the back of the sub. When it is receiving a signal, the light is green. When it hasn't received a signal, it is red. The light keeps coming on as if it were recieving a signal. I'm using a Monster Power Surge Protecter (the SW200 I believe). It is specifically designed for a subwoofer. I have tried to detect action by the subwoofer from both test tones and by playing bass-enhanced CD's. What do I do next? Any suggestions? Thanks in advance.
