Question about Sony STR-DA777ES 6.1 Channels Receiver
Hooked up my surround sound to my sony receiver and only half of the speakers work what do I need to do to get all the speakers working?
SOURCE: Surround Speakers stop working
More then likely unit has poor solder connections. Try lightly tapping on chassis to see if you can get audio to either cut on or off with the vibration, If you can unit has intermittent solder connections probably around power amp ic701 where most of the heat is generated. I have a PDF service manual if you need it for yourself or for a technician if you take it in for repair email@example.com

your problem is a bad solder connection of the relay linked to the lautspeaker sockets. I had the same problem and googled for the solution. Since I resoldered the pins everything is fine. That problem is well known and happens to a lot of Sony receivers.
I can send you a link with a detailed how-to-do solution with pictures, however it's written in german language. But you can use some online translators.
