Question about Onkyo HT-S790S System

1 Answer

Sound, but no video

Our system was working for nearly a year. Then on evening after watching our cable tv through the onkyo theater system and shutting all components down as usual, the video quit working. The next morning upon start up, we could hear the cable tv through the speakers, but the tv showed the message "weak signal". We checked all wiring connections. All was intact. We tested the cable box. It works normally when connected directly to the tv. It just no longer works through the onkyo for video feed. We checked the manual for troubleshooting. None offered for video problems. We called. The tech could not solve the problem. Any ideas before we bring it in for service? I have seen the same problem in posts on other onkyo theater systems in this forum.

The video is switched by a single chip similar to the one that switches the audio signals. It is possible that the chip is defective. Even as a shotgun approach, changing the chip shouldn't be more than $15-$25 for the part.
Keep us posted.

My sound on Onkyo HT R 548 stopped working


If this is a Surround Sound System you can check channel and audio tone levels using the remote. Check remote for a receiver button followed by Test button. Check manual for test instructions.

1. The easiest solution would be to connect a stereo RCA (red and white) cable to the audio output on the back of your TV.
2. Then connect the other end to the input on your home theater system.
3. Change the home theater system to the correct input.

Good luck!

Why cant I supply my onkyo surround sound system


You need to assign the HDMI input(s) to the functions they represent, using the Front Panel Tuning/Preset control...

If you connect a video component to an HDMI input, you must assign that HDMI Input to an input selector in Setup.
For example, you could assign the “DVD” setting to “IN1”, and assign the
“CBL/SAT” setting to “IN2”.

Likewise if you use digital audio inputs...

Assigning the Digital Input
If there’s no sound, press the [DIGITAL INPUT] button repeatedly until sound is heard. The digital input is now properly assigned.
If you connect your DVD player to the AV receiver’s COAXIAL 1 DIGITAL IN, and your cable/satellite receiver
to the COAXIAL 2 DIGITAL IN, as shown, it’s not necessary
to assign the digital input.

Hi and welcome to FixYa,

Initially, postback with the model numbers of the cable box, the DVD/VCR combo, the TV and the Onkyo. Additionally describe the plug/cable colors used form what jack of what device to which jacks of the next device.

Offhand, it would appear that the connection is basically output of one device is fed as the input of the following device. That being so, each of the devices (except the cable box) would have to be set for which of its inputs was used.

Good luck and thank you for asking FixYa. Merry Christmas.

No audio from my PS3 through the Onkyo 5100 7.1


if you are using an HDMI cable dont expect sound to come out (even thought HDMI carries both audio and video) the onkyo HT-s5100's Receiver is the HT-r560. the 500 models of the onkyo receiver does not allow HDMI to carry both audio and video. it only allows the video signal to pass to the receiver.

if youre using optical for audio w/c is what you need then these are the steps you need to follow.
*first make sure that the optical connections are ok at the back of the receiver.
*make sure that your DIGITAL INPUT is set to either OPT1 or OPT2 whichever optical input you used to connect the optical cable.
*then go to your PS# settings : go to sound settings / audio moutput settings/ select digital out (optical).

then enjoy.....ü

No sound with ps3, connected to a 7.1 av receiver & projection tv


Hi...the HT-R800 Home Theater system has the HT-R550 receiver which could only carry Video via HDMI. you would need to connect a separate audio cale(Optical Audio Cable) to be able to get audio out of the PS3 to the receiver. Once you have hooked up an Optical Audio Cable you would need to go in the PS3 setup and putin Bitstream and Optical in the Audio Setup menu.

Hooking up a sony playstation 3 with digital optical cable


Here's one solution, if you have an audio output from your tv, you can go from the audio output on your tv to the audio input on your receiver that way anything that is playing on your tv for example, playstation 3, dvd player etc. Anything playing on your tv will have audio on your onkyo home theater system. The other thing I would try if you want to hook ps3 directly to receiver is go to your connection settings on your ps3 menu and change your connection method to digital optical cable.
