Question about Onkyo TX-DS797 Receiver

Onkyo TX DS797 no sound from cable TV

For not apparent reason we can't get sound from Video 2 (which we use for Cable TV sound). We get sound from other sources (FM / Component 2 (XBox) / DVD. We didn't knowingly change any settings. We get TV sound from the TV. Any ideas would be welcome. Thank you.

Re: 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.

I have an audio problem with my TX-SR502.

If your remote also controls the Cable Box you might want to look at its audio settings. Maybe you muted it.

BTW: it would be a good idea to also run video and analog audio from the cable box directly to the TV if it has speakers so you can watch and listen independent of the Onkyo.

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.

Picture sound blackout (blink) when cable box/receiver HDMI used

Onkyo service told me, the second timethat I called them, that there is a known HDMI handshake issue with Motorola and Atlanta Scientific cable boxes. The only solution, and it was a solution, is to connect the box through the HDMI 1 port ONLY. All the other (2,3,4) result in blinking/dropping of signal. I did this, changed the cable/satelilte setting to HDMI 1 and all is well.

Onkyo TX-SR304

Onkyo offers access to manuals at their web site. HERE is a link to the receiver line.

Personally, I'd connect the speakers to main left/right. The subwoofer to subwoofer out. The Go VIdeo unit to VCR/Video 1, the cable box to Video 2 and the video output to the Sony TV composite input. No need to connect the TV audio out to the receiver since the audio feed comes from the cable box.
