No sound problem is power amplifier trouble maybe the IC there is defected or cold solder of joint of the parts.Cold solder issues - each component is soldered into small holes on the printed circuit board which in turn connects said component to the other components. Due to time, heat, use, some solder joints would be cracked or loose. It is possible that the cold solder is still minimally connected (hanging by a thread). When the receiver turns on heat would be generated which would be sufficient to further loosen up the solder joint to the point it no longer provides electrical contact. Jarring the unit creates movement inside enough to re establish the contact, sometime good enough sometimes not enough.

Again, since the unit still operates (sometimes) then it is highly probable that there are no defective components. As you have surmised, it is possibly a loose connection, solder joints are "connections" except that molten soldering lead is used to attach/connect the component to the board, "loose connection" in this sense is equal to "cold solder".

Again on the assumption of no defective parts, then seeking a more experienced buddy for the soldering might be to your advantage. This is of course in addition to the possible electrical hazards when repairing....If i have helped,please click fixya.It is the only way i get paid for my work...

Good luck:

Russound ca4-kt1 no sound


Does the system have its own speakers? I understood that sound system required speakers to be attached. Check that you put the right model up.

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.

When it says 'no controller' on CAM6.6T what do i need to do to fix it?


Have you called the installer that put the system in? No Controller means exactly what it says: the keypad powered up and it doesn't see the controller (CAM6.6). This can be caused by a short or break in the Blue pair of the CAT5, the punch down on the back of the keypad or the RJ45 connected to the port on the back of the CAM is loose. Should be easy to troubleshoot for someone familiar with the installation of the system.

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.

Capacitors may need to be replaced they begin dying out over time and need to be replaced. They usually hold a amount of electricy so that when you start the component there is no waiting period when they dry out or begin to fail in time it may become longer and longer until it stops coming on at all.

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.

Onkyno receiver shuts off


My SR605 gets extremely hot. This is especially true when both amplifiers are running together supporting 2 separate channels. I added a 2 way speaker selector from Russound that supports 2 sets of 8 ohm speakers on Zone 2 and the receiver shuts down at about 74 dcbs and gets very hot. Checked the jumpers on the selector and they are set at 8ohms.

Have returned the Russound selector to them and had it checked out. Appears to be fine. Even when Zone 2 is not in use the receiver gets extremely hot. It is in a wood cabinet wih glass doors but even with the door open the temperture is very hot. As the volume is raise the heat increases and the receive trips off.

Very unusual in my opinion. Is this normel for the receiver to heat up as the volume is increased.
