I had a right speaker go out on me. I solved my problem now everything works fine.
When I picked up subwoofer I could hear a small rattle in it (a tiny screw or some small
part). After removing the plate I found that one of the fuse clips (there's two fuses inside
2.5 amp tiny ones, one of the clips had broken and the fuse dropped, fell off. I took
it to a tv repair and had a clip soldered in, I just replaced the fuse and all's well now.
