Onkyo TX-DS797 - No sound

After 4 years of good operation the sound from the unit has suddenly gone. The video works fine but there is no sound from any of the outputs including FM or AM radio. Any suggestions?

    I have an ancient Onkyo Quartz Synthesizer Tuner Amplifier RI. I am unable to get sound from the cd player (nothing has moved, been distrupted, etc.). In the past, I would occasionaly hit a button (video -1, video-2 etc) and not get suds,but after some random button hitting, I cannot get it to work (get sound) again. Any suggestions? Thinking it may have to do with the APR SYsyem slection (only lit when the FM tuner is selected) but can't figure out how to reset. HELP!!!!!!

Onkyo TX-SR701 getting sound but not picture from Video 4
you should check the video mapping in the setup of the receiver. video 4 may be associated with hdmi or composite video instead of component.

I have an Onkyo TX-DS797 it is about 6 yrs old
These units *(if I remember correctly) had a problem with a memory IC in the surround porcessing section that would show up initially as popping and would eventually end up with no sound at all. This is a straightforward repair that involves replacing the IC with a new one (different manufacturer). The problem is that this is a surface mounted IC and is difficult to replace without damaging the underlying PC board. This is NOT a DYI repair. Have this unit checked by an authorized Onkyo service center.

Onkyo TX-SR502 AV receiver
this could be the pre amp transistor or the power amp that needs replacing
the pre amp transistor is cheap but the power amp is not
if you did not crank it , then it is probably just the transistor that needs replacing

No Sound
Called Onkyo and here is the solution they gave me.

1. Turn on unit.

2. Press and hold VIDEO 1 button.

3. While pressing VIDEO 1, press Speaker A button.

4. You should see "CLEAR" on the display for a second and it will go on stand-by mode.
.
5. Turn on the unit and check if sound is back.

Hope this helps

Onkyo TX DS797 no sound from cable TV
Have you made sure the receiver's INPUT SELECTOR is set to "Video 2"? I know it seems like a stupid question, but worth mentioning as many folks would set the receiver on TV, which would not work unless the signal was also plugged into a "TV input" in back of the receiver. If your setting is correct, try running the TV cable sound temporarily into the receiver's DVD input, which we know does work. If you still don't get cable TV sound when the receiver is set to "DVD", then you have a problem with the TV cable audio portion. Most receivers would fail completely, rather than have only one input fail, so my guess is that there is a hookup or switching error somewhere.
