TX-DS494 Surround Sound Issue

My receiver seems to have lost its ability to provide 5.1 surround sound. The only speakers that work are the Left and Right front speakers while in Stereo mode. It is unable to produce any sound using the optical or cable inputs from my DVD player or my cable box. The Dolby Digital light also no longer illuminates when DVD is selected and played. The nail in the coffin is that the Test Tones do not work for any of the 5 satellite speakers. I triple checked all connections and settings. While trying to get the test tones working, I turned up the volume almost max and I could hear a constant, very soft 'hiss,' so I know that some power is getting to the speakers. I have a feeling it's an internal issue. Please let me know if you think I should head to the repair shop. Also, any recommendations for repair shops would be appreciated.

I dont know if you already fixed the problem. but I have this problem before, and luckily its not internal. Check your speaker switches, speaker A and B. one of them only do stereo.

I have a Onyko TX-SR303 5.1 Receiver and sound is only coming out of left front speaker.

Could be the IC that controls the various sound/surround channel modes. Had that happen on my Pioneer receiver.
Charged me close to 200 bucks to fix!

7.1 would have Surround Back L and R.

6.1 would have just one back there (SB). It defaults to the Left output on the Pre-Outs if you ever go that route.

This being a 6.1 receiver it does not support two SB channels BUT you can configure those amp channels for a separate Zone supporting 2 speakers. Confused?

The manual shows a single SB speaker connected to the left side on Page 27. THAT would be consistent with a 6.1 configuration.

Error s10

Did it ever work properly? If not, let's get down to basics and set it up for the simplest configuration it can have: FM source in stereo with front left and right speakers, no Surround Mode, no DSP, no Tape Monitor, no Mute, Volume not turned all the way down. Does that work?

Do you have Surround Speakers defined in System Setup A? If not, only Dolby Surround or Off are valid Surround Modes.

Is T2 Monitor indicator lit? Press the Tape-2 Monitor.
Is there acceptable sound other than during Speaker testing? NO? Is MUTE On?

Garbled / feedback sounds from powered subwoofer

The surround processing portion of the unit has a problem. In either stereo or direct mode, the digital procesing is bypassed. This could be just the surround processing IC, but that IC may not be available as a separate part. I would suggest that you bring this unit to an authorized Onkyo service center for an estimate.

If you are connecting a 5.1 surrround sound rather than 7.1, have you connected the surround speakers to the surround left and surround right rather than surround back left and surround back right?

No sound back two speakers

After using the method of last resort (RTFM) I discovered that Yamaha 7.1 amps assign an order of priority to the speakers. The surround speakers have higher priority than the surround-back speakers. I had connected the rear speakers (in a 5.1 configuration) to the surround-back speaker terminals and since nothing was connected to the surround terminals the E-6 error happed on auto-setup.

I eventually fixed this by connecting the rear speakers to the Surround L/R terminals and then, via the manual setup menu, set rear surround = NONE. This causes the amp to route the rear-surround signals to the Surround L/R terminals. The auto-configure then completed successfully.

So your saying that you have no rear channel. Some recivers use a single stereo output ic for both sides on the rear speakers. you could have a defect with this IC . Anther thing Im sure you check3ed the obvious ie : the switch is on suround sound? If there is a front to rear fader is it in the middle? Good Luck
