It is major hardware failure on the device, as long as you have tried rebooting it (unplugging for 2 minutes and replugging). Then it is the internal processor or other major board that has failed. Many things can cause it not to output sound... could even be a solder point that broke inside the unit on one of the boards. No easy fix for this but you can take apart the machine and look for physical damage if you want to try and fix it yourself.

Thanks

Why won't my Roussand R850MC amplifier play sounds into our multi-room setup?


Sounds like one of the power amplifiers in your Russound has a short. It's not a difficult repair for a good technician. Try a local stereo shop or send it off to Russound.

Russound CA6.4 amp / controller - 3 of the 6 zones can't switch source inputs.


I suspect the inputs will all go into an IC. You just need to trace one of them back till you come across it. Either the circuit around it will be the problem, or more likely the IC itself.

I have a Russound Cat 6.6 6 zone receiver that will not power on. Any ideas on what I can do to fix it? Is there by chance a reset on it?


If you are getting no lights on the front of the CAV check the plug connection to the back of the unit as well as the plug on the power strip. Make sure the fuse on the back of the unit is not blown. The specific fuse rating is listed in the manual as well as on the back of the unit. If it is still not powering up you may have to request service from the company.

No sound from Russound ss-4 after connecting to BACK surround speaker connections on the 2807.


Check the speaker setup configuration in the setup menu. Many times the surround back speaker terminals can be assigned to something else like zone 2. They may just be turned off.

I have no output on my Russound ca6.4. All lights on console and room controllers appear to function. Input double checked. Could amp be fried?


CA6.4 that has no sound, but all other funtcions are fine, has a problem with protection IC 10 (uPC12370). Check the Cap C28 (2.2uF/50V). If you read any AC
Volatge on that Cap, it means Cap is dry. Replace it with 4.7uF/50V and go back to
your regular duties.
P.S. Since the unit is discontinued, I would love to see basic diagram, available from the manufacturer for download, for easy troubleshooting. I had to spend feew precious minutes to fix that.

I have a Russound CAV6.6 Rnet controller. The controller will turn on, but I can get any sound out of the speakers. It used to work just fine. Now the lights come on, but no sound from the speakers. I took...


Have you changed any connections behind the CAV recently? This happened to an associate of mine once and it just turned out to be something simple. This may or may not be the situation in your case. Check to make sure your source audio cables are connected to the correct source number that you assigned in the programming (Ex. AM/FM Tuner = Source 1). Also make sure your audio cable is connected to Source 1 IN (and not the "OUT").

Narrow down the source of the problem:

Make sure the keypad you are using to test the CAV is not in "Mute" mode. Press the "Pause" button to engage/disengage from mute.

To further troubleshoot your issue if the above is not the case you want to use a device (such as an ipod tthat you are sure the audio output is working using a stereo mini to red and white rca cable) and plug into each source input (one at a time) behind the Cav then monitor that source# on the keypad to see if you hear the ipod on any of the sources. If you hear the ipod playing on some sources and not others it obviously means some of your source inputs are having problems and the unit needs to be shipped to Russound for repair.


Make sure the front of the Cav6.6 has the proper colored lights lit up. When no keypads are on the zone should show red, when a keypad is off the color should be green for that zone, if there is a short circuit with the speaker wire the CAV might be in protection mode and the color might show orange.

Hope this helps.
