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.

Without knowing exactly what your problem is, perhaps you are not playing sound that was recorded in at least 5.1 format. A DVD or BluRay will indicate the format on the cover. The data is decoded and split into (for example) six discreet audio channels. Left front, Centre front, Right front, Surround Left, Surround Right and LFE (Low frequency effects) If you are playing a standard stereo audio disc, then the sound will only be heard from the front L&R speakers, which are expected to be full range speakers. You can, however choose an audio configuration that also provides a signal for the SUB (LFE) and even a pseudo surround. If you want more info I'm happy to help. Just tell me exactly what sound source you are playing and we can work it out.
Cheers for now, Don.
Alright i had a chance to look over things, this is how you are going to hook up the sub. first we'll be connecting the surround sound unit to the sub woofer. surround sound unit sub woofer left front: positive (+) <-----to------------->(+) left speaker level in negative ( - )<- - -to- - - - - - ->( - ) left speaker level in
right front: positive (+) <-----to------------->(+) right speaker level in
negative ( - )<- - -to- - - - - - >( - ) right speaker level in
now that the surround sound unit is connected to the sub woofer you will need to connect the front surround sound speakers to the sub woofer. sub woofer front surround sound speaker left speaker level out (+)<-----to--------> (+) left front speaker left speaker level out( - ) <- - - to- - - - ->( - ) left front speaker
right speaker level out (+)<-----to--------> (+) right front speaker right speaker level out( - ) <- - - to- - - ->( - ) right front speaker
Alright now that the wires are all over the place and plugged in turn everything on and see how it sounds. let me know if everything is working as it should. if you need help with anything else or if something does not seem right please feel free to contact me via e-mail or phone Mark Woodring
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?
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.
