hello, did you figure out how to wire the sony subwoofer?
I have the opposite problem you have/had. I have a good TV and no speakers. If I can crack the code I can connect a different brand sub.
Interested in selling yours?
I have an older Sony XBR that had the big subwoofer component that sat on the back of the TV and two satellite bookshelf speakers that hung on the sides of the TV. All were powered by the TV. The TV is toast now but the subwoofer and speakers should be fine. The subwoofer has a Sony proprietary connection plug that connected it to the TV. How can I re-use the subwoofer and speakers?
