Question about Onkyo TX-DS747

1 Answer

Speaker switching problem

Basically mt reciever is switching between A & B speakers like a little kid is playing with the buttons with or without speakers connected, it will turn on "A", turn it off, turn on "B" turn it off and continue thusly until I get frustrated and turn the machine off sound does come out of the speakers for the second their side is on, but otherwise it is the repeated clicking of speaker switching I have a service manual, but am not about to poke around something I cannot see, and for some reason I cannot locate the source My Onkyo TX-DS747 will not hold the selected speaker setting but keeps jumping back and forth from A to B. As I have it set to the A speaker system, there is no audio until it jumps back. When it warms up it may stay in the A position but it is taking longer as time goes on to hold the A position. A and B buttons are clean and have positive switching when pressed. I have not seen a possible solution on the FixYa site. I will add my issue to the list of users with the same problem and hope an expert can add some insight. Thanks.

I really hate to say it, but I would say the capacitors are gone. You can send it in for service but beyond that there is not a magic series of buttons to press to fix this.

Kenwood KR-V7080 reciever will not play through speakers.I can still plug headphones into the reciever and get audio but not through the speakers. Tested the speakers and they still work.


If the speakers used to switch off when the headphone plug was put in the socket, suspect the socket it goes into as being the trouble. It is clearly not connecting the speakers, when the headphone plug is removed.

Playing cd's no sound from the speakers when I have the cd/dvd option selected. When I put the reciever on I can hear dead air coming thru the speakers but not when I have the cd switch selected....


You need to find the manual and/or read and understand every indicator and evaluate how it affects the sound. Use a medium volume setting while troubleshooting.Check connections.

Start with the basics. Speaker test ok? FM ok. Digital sources assigned yada yada.

Only the front speakers failing? All others ok?

There is NO configuration that would have NO front speakers.

Go back to basics, open the manual and use test tones for speaker verification.

My denon avr1200 receiver once it is turned on goes into Protection mode. How do you reset or make work?


The reciever will go into protection mode when there is a short in the speaker wires or the amplifier was overloaded. What I would do first is verify that none of the speaker wire connections are loose at the back of the reciever or at each speaker. And verify that none of the wires are making contact with each other. Then label each speaker wire as you remove them from the reciever so you can re-install them correctly. After you have disconnected the speaker wires try unplugging the reciever for 10 to 15 minutes. Most recievers have a self-resetting overload protection switch and this should reset it back to normal. Now try plugging the reciever back in and turn it on without the speaker wires connected. It should be out of protection mode now. If it is still in protection mode verify that there is not a reset switch somewhere on the back of the reciever. If it is not in protection mode now then proceed to connect one speaker set at a time and turn on the reciever to see if it goes into protection mode. If it goes into that mode after connecting a speaker then that speaker is the cause of the problem. If it does not go into the mode after all speakers are connected then try turning the volume up. If it goes into protection mode then there could be an internal short on the amplifier or a incorrect OHM rated speakers connected to reciever. Verify that the speakers are rated the correct OHMS.

Your system is designed to interrupt the signal flow once headphones are attached. It can not be changed without internal modifications. There is no control to do this.

XBox 360 to Reciever to TV via HDMI no sound


I recently got the same receiver and had the same problem. Here's what I was told - and it worked for me:

Even though HDMI cables carry audio and video, for whatever reason this reciever won't accept audio through hdmi. Apparently only much more expensive recievers carry audio through hdmi. What you have to do is run optical audio cables from your xbox, cable box, dvd player or other video device to the optical inputs on the back of the reciver. Then you customize the scene buttons to match your video and audio inputs.

You can get these optical cables pretty cheap on line or even at target. Don't get ripped off by Best Buy for these cables. I love best buy, but they rip off on cables!

This receiver is great - once I got it all figured out and running right I've loved it! Hope everything works out for you!

Center and surround speakers work, but front right and front left speakers do not put out any sound


I had the same problem. Set the reciever on 6 channel stereo. On this setting, you should be getting the same sound out of each speaker. Isolate which speakers aren't getting sound. Now, on your speaker switch (the A/B button), select A. If that doesn't fix it, select B. If that doesn't fix it, try A and B (if you can on your reciever).

Now, when you switch back to pro-logic, make sure your a/b channel switch is in the position that worked in 6 channel stereo. Yamaha recievers have a memory, and when you switch various modes, it makes auto adjustments based on what you had set in the past.

Hope this helps

Sound control is via TV remote only


You didnot mention wehther you selected external speakers on you tv. If your TV allows this then do that, first.

Also the sound input to your TV must come from some source, (cable/ Sat). You could remove the audio inputs to your TV and only allow the audio to go to your Receiver.

RCA cables will allow this to be easy just remove the red and white audio to your TV. If you have sent them to your reciever then you must balance the cable box volume (reduce to the lowest level , then raise your recievers vol until satisfied if you are to loud when you switch to a CD then raise TV vol until they match, so your CD doesn't play to loud when switching modes)

If you are using an HDMI cable to your tv than there has to be a setup for turning off the internal speakers on your TV.

Speaker switching problem


What the type of switch you have there? its like a push button or a soft button? Often you have a contact switch problem on your unit. I f can access the switch contact and clean it that maybe can help on your problem.
