No right output

When you say it didnt switch when changing cables?? Well if you have no output on the right speaker and you put the left speaker on and still had no output then its your speaker as the problem should have switched from right to left if the problem is in the reciver. Now you could check and see if there are any bent control shafts as this is common durring a move and that would account for the problem or there are internal speaker fuse that may have popped out but this ones doubtfull, or the preamp or main amp printed cuircut board has a crack in them?? If you checked all mof these and need assistance with this repair you can go to the manufactures website to see how and where you can send or take the unit for repair.
