Question about Sony STR-DB930 Receiver
I am an audio neophyte. My rear right speaker is not working after very carefully packing and shipping my Sony receiver for a move. Checked the speaker and speaker wire to other connections and they both work. Leads me to believe it's the receiver connector for the right rear speaker. Any ideas what may have happened? Is this (easily) fixable? Would you do it yourself (as a neophyte) or take it somewhere? Any suggestions would be appreciated. Thanks!
These receivers have a common fault with the relay on the amplifier board. If you open the lid, the rear amplifier PCB is on-top in the centre. The relay is in the middle of the board. It should be easy enough if you have a multimeter to check the contacts are closing correctly, if not then replace it, the specs are printed on the side. If you are not confident then don't try it, these are powerful amplifiers with +/-60v DC rails. 120v DC can do you some damage if you get it wrong!!

You can open the reciever and see if there is anything visual. If there are any parts failures these would not be visable. You can check to see if there are any blown fuses.
You may have to give the reciever out to an experienced service tech to troubleshoot it to find out where the failure has occured. These recievers can be complex to service.
