I recently moved my onkyo HTIB and when I got it all set up again, the subwoofer wouldnt work. I heard a slight rattling inside, so I took off the back and found some orange thing that looks like a binkie with wings on it So I took it out...anyway, I went to replug it in and the sub only works when the wire going into the receiver rubs the outside of the input on the receiver. When I plug it in though, it cuts out. Why is this happening?! Thanks in advance.
