Mine does it as well. I just go back and forth from video to cd to something else and after a minute it works fine.

SOURCE: seems to be stuck on

Mine is having a similar problem. After it has lost power or been unplugged it will always revert to decoder 4. It seems to need to warm up because after waiting about 10 minutes it finally stays where I tell it to.

My RX-V665 receiver lost its sound for no apparent reason while we were watching a show. It was in HDMI mode and has the message "Decoder Off". The sound works with a DVD and a CD, just not...

It's telling you the digital decoder is now "off" and will treat everything like 5.1. THAT is a selection you choose, not a status that spontaneously appears. Perhaps someone unknowingly touched the remote while playing.

Get the manual out and read up on DECODER. Page 61 (Troubleshooting: NO SOUND) suggests "A proper audio decoder is not selected". Try AUTO.

Or, track the digital source of your TV audio back to make sure it still works.

In the display it shows(decoder off) and not able to play music ,how to turn on the decoder?

I sense two different problems or one not completely described.

The followinbg would address the decoder issue.

It partially depends on what it is you're trying to play or how you like to hear it.

Check the Direct Mode Button and make sure it's not activated. (M on page 4).

Straight Mode (L on page 4) is a desirable starting point for multichannel material.

See page 24 of the manual to see all the things this beastie can do with all of the audio inputs.

Be advised that most commercial multichannel sound sources have been pre-mixed by the originators to provide an intended 'feel' and 'space', so modifying it might not be an improvement although it can provide a novel change. Like any spice, a little is best.

I find that processing 2-channel audio through the various DSP modes can make for some interesting and arguably pleasing effects.

If you 'search' the document for the word "decoder" it may lead you to a setting that's out of place.

"Not able to play music" should only happen if you have a source incorrectly chosen or the source is DTS and the decoder is off. Undecoded DTS will sound like high-level digital 'hash' noise because you're hearing the raw 'data' so it must be decoded to turn it into audio.

See the note on Page 2 regarding DTS-CD's then look at Page 33

I hope this was helpful.

How do u know if the decoder for dd and dts is working

When listening to digital source (HDMI or spdif optical/coax), press Option button on remote and choose Signal Info submenu. There you can see info about number of channels, bitrate and decoder which is currently used.

I have a kenwood vr-707 it gets surround sound on dvd/vcr but I can't get surround sound on just tv.

Well you have a built in decoder/surround processor that will detect a signal with the surround sound info(dvd/sat.receiver/cable converter etc.) and will then process it to the different speakers on your system. In the absence of that signal it will process it as standard stereo sound(two front speakers). You may want to look in your receiver functions/menu for simulated surround.
Hope this will help.

Input selector on my Yamaha RX-V596 stuck

Hi Dush

Sounds like the processor has locked up in the unit. Try powering it right down from the wall socket for a day to reset, and then retry operation. If that does not work, leave it disconnected for about 10 days to erase backup memory completely and then try again. Good luck. Don't forget to give me a "FixYa" rating if this works. If it doesn't, get back to me in here and we can talk more about it.
