Question about Onkyo TX-SR605 Receiver

1 Answer

Onkyo HT-SR750 Just purchased a new Onkyo HT system that connects to a Mitsubishi DLP TV via Dish Network HD and a Samsung DVD player. I've run the sound setup and can hear through each of the separate speakers. I get video from both SAT broadcast and DVD, but no sound whatsoever from any input source. I have HDMI cables only running from both SAT and DVD into the receiver, and then a separate HDMI cable running into the TV. Need some serious help since I've spent hours on this and nothing works. thanks, Tom

Re: Onkyo HT-SR750

Check out Onkyo's website: The HT-SR 800 description says "a separate audio connection is necessary" Maybe it is true for the --750 too.

Onkyo HT-R693 (HT-S7700) receiver will play video but no audio on Netflix and YouTube. However, sound comes through when connected to Comcast cable and even Pandora. I have tried the different channels...

  • Check your cable connections
  • set the input selector to the proper component sources your using.
  • set your speaker settings to either 5.1 or 7.1, according to your speaker configuration via Onkyo's AccuEQ automatic setup tool- because the same binding posts can be used for hooking up the Atmos height or surround back speakers; you'll need to tell the Onkyo system which setup you're using.

Onkyo tx-sr604 help

You said you tried hooking the HDMI up directly from the TV to each component, and that worked. How is it usually hooked up - through some kind of switch? I'm not completely understanding your setup here.

HT-RC360 no longer feeds video to my TV .

Update firmware (usually every 6 months). Connect the ethernet to the unit, press Net and Power button simultaneously. Hit Enter as directed. Takes up to 60 minutes. OR (if no internet service), download firmware updates onto a USB (32MB) and connect it to the USB port. If you do not update voluntarily, unit will suddenly not feed video.

Sound from Onkyo CD player well and fine. Then connected the Samsung DVD HT-Z310 to Video3 (L/R audio in, V-in from L/R Audio out and V-out of Samsung) but no sound or nor video on TV? Tried to fix it...

What am I missing here?

There are a lot of models mentioned in this post. What are WE discussing?

* A Samsung HT-Z310 is a Home Theater System.

* An Onkyo TX-DS777 is higher-end AV Receiver that DOES have a Video 3 input which accepts composite video and analog audio.

* An Onkyo CD player is irrelevant to the TV sound in any scenario.

* Unnamed TV.

I don't see any path in your narrative that would carry audio TO the TV. Is there an unmentioned HDMI cable in here somewhere? I see no other audio outputs on the HTZ.

Are you running the HT-Z310 through an Onkyo receiver to somewhere (?) else?

The fewer hops and inteconnects a given signal experiences between its source and your senses, the better. I always run the BEST video from any source to the TV first; the best Audio to the BEST audio electronics. If that helps.

How do I hook up my Onkyo receiver to my dish network box?

Take the cables from the receiver to the tv and connect it to your Onkyo where it says "in", then take another cable and run it from your Onkyo receiver where it says "out" and connect it directly to the tv. Make sure you cycle the inputs on your receiver and tv, so you get sound and video.

Connecting a Dish 622 Receiver to the HTR500 and a Sony HDTV TV

I haven't researched to actual manuals for your equipment, but I'm guessing that the optical may be disabled when the HDMI is used. You could try using the component video outputs to the TV and then the optical to the Onkyo.

Hook up

Karri, I do not have the photo of the back, but attached is a general wiring diagram for any Audio-video Home theater system. If you have a Home Theater Receiver, then hook it up as the diagram. If not, hook it up per the comments in the diagram. This is how I hooked up my ONKYO HT system with my SONY Combo DVD recorder and my Mitsubishi TV. One thing to note on Combos, is that the VCR Tape section will not play through the High Definition connections (HDMI, and Digital Audio). You have to use the older method of Audio-Video (AV) cables or the Co-axial antenna cables. You can ask more questions if there is any confusions. Hope this helps you. Good luck.
