Sony STR-DE685 Receiver Logo
Posted on Jun 27, 2010

The receiver works ok until the vol is reduced and the right front channel drops out. Increasing the vol usually picks up the dead speaker but it drops out again when the vol is reduced. I've tried different speakers and disassembled the receiver the check all of the rear input/output module connections and they all look ok and the problem recurred on re-assembly. Any ideas? thanks in advance

Make sure the audio level on the left and right channels are balanced. Check the menu for audio levels to adjust and make sure they are not maladjusted. If all levels are adjusted properly then the volume control or volume control circuity may be at fault.

    I have the same problem with this receiver. I should have suspected something when the first one I bought from Best Buy I had to return because not all of the 6 speakers were being driven when adjusting the 5.1 sound levels. I returned it and they gave me one that worked for several years. Then the front right and rear left channels started to fade. I think the output stages in these amps must be ****. I may try and take it apart and maybe replace some power transistors, don't know yet. Should have opted for a Denon I guess.

Hooked to surround sound, two front speakers, 4 wall speakers, 1 sub woofer. Restart unit and reduce volume unit is OK but normal talking is too low.

Voice tracks are usually routed to the center channel. You don't mention having a center channel speaker hooked up. If this is the case, then you need to go into the receivers setup menu and set it for no center. This will reroute the voice tracks to your front speakers.

No problems for serval years. Right sound output died on both speaker and headphones, very slight buzz on increasing volume. Left sound output okay. Suggestions please. Jim Conway [email protected]

I presume you have proven the channel is dead by trying multiple sources, swapping a different speaker onto it and that the balance control is NOT all the way to one side; headphones don't work either and we're down to proving it's dead before you take it in to a tech, right?


There is the slighest chance that a common control may have developed a high-resistance or 'dead' spot and is causing your symptom. Turn the POWER OFF and operate every control throughout its range a number of times, especially rarely-used ones like Tape Monitors and the Mute control.


If it still doesn't work you might want to prove if its a low-level signal loss or a high level amp failure. One way would be to run an RCA cable pair from the Tape Out to any other device (even a TV with speakers) you might have that accepts an audio input. If IT can't detect receive the DEAD Channel you

My front right speaker is not increasing however when i place the speaker on another output it works fine. The sound is very poor and does not increase.

It sounds like drivers or the output IC is the problem in the right channel, this is a repair that will require a professional to address this situation.

No sound from front left channel

Try swapping the connectors for front-left and front-right (just swap right at the back of the amp)

After the swap, does the front-left speaker work, and now the front-right is dead? If so, then it's a problem in the amp.
If not, then the problem is in the wiring and/or the front-left speaker itself.

Post back here with your findings, and we'll troubleshoot whichever part of the system is broken.

STG DR510 no sound on left front channel

Can I assume the calibration procedure also didn't work for the Front left channel? (It's not a "surround" if it's in the front). Switch the receiver to Stereo mode to eliminate any DSP actions. Tune an FM station to eliminate any external device or cable issues. What do you hear from the two Front speakers?

OK? Select a DSP surround mode. Check all modes. What happens?

If the channel goes dead using some or all DSP modes there's probably something wrong with the processor. If they all work...

Isolate the source that exhibits the problem.

It was a bad left channel cable somewhere, wasn't it?

Left channel not working

The first thing I would check has already been done, the only other thing would be fuses. I am preety sure there is a protection fuse at ever channels output to protect against a dead short. I am sure you have already fixed this problem but I thought I would give it a try. Let me know what you found.
