Question about Sony STR-DE845 Receiver

1 Answer

I have a Sony STR-DE635. It has a switch on the front for speakers A, B, and A+B. Normal. When I am on speaker A only, it works fine. B does not work. A+B works, but only through the A speakers. Now, running through the demo mode, static comes through the B speakers, so it's not the connections. When I swith from A to B, I hear a clicking noise in the back, like something has actually switched. Here's the cool part, on B, if I press in on the front by the switch, the sound will work for a second or two, but i have to keep pressing in. Does anyone how I can fix this?

Check for bad solder connections on the speaker switch or where the speaker switch board connects to another board. Not an uncommon problem with some Sony receivers.

Where do i find an A/B speaker switch


It's probably not the switch. These models have a common problem with the solder connections between the switch pcb and display pcb going bad. You need to resolder these connections, and your problem should be solved.

Bought some replacement speakers and the reciever seems to get ver hot!


Hello! Yes, you need to worry when a Sony gets hot!! You probably have replaced factory 8 ohm speakers with 4 ohm speakers. Look on the back of your new speakers and see what they are. Then look at the rear of your receiver by the speaker terminals and there will be a sentence like "8 Ohm minimum per channel". If your Sony says " 8 ohms " you need to use 8 ohm speakers.
Also, are you a using low level signal ( audio out ) to drive your sub or are you using high level ( speaker line )??? I'd use low level. Good luck!!
