Russound CA6.4i home sound system does not make any sound

System makes no sound. Unit powers on, and lights on base unit operate normally. Remote controls light up, and function normally. However, under normal operation, when one turns on a set of remote speakers you hear a relay click in the base unit, a light on the front panel turns from red to green, and sound comes from the speakers. This unit does not click when a remote speaker is turned on, and sound does not come out of the speakers, but the light for that zone does change from red to green.

    I have solved this problem. The problem is that the audio output was being shut down by protection IC-10. Taking pin 6 of this IC low enabled the output. I replaced C28, a 2.2uf/50v electolytic with a 10uf/50v electrolytic and the unit powered up and worked fine. These components are on the lower PC board, located slightly up and to the left of the center of this board.

If the board is not cracked , check voltages at the audio output relays. on the input audio terminals side of the relays ,if you have voltage you may Have bad output Ic's

Without looking at the schematics for this particular model, I'd surmise that the click is indeed a speaker protection relay. Generally this is fed by a number of different sense circuits that watch for power amp issues and/or excess speaker current and/or power supply output stability. Although the relays do indeed fail at times, generally it is not the relay that is at fault. If you have a scope and a schematic, you can check the various circuits that feed the relay for the exact cause. If not, you can do some experiments that might help deduce the problem: e.g. do headphones work when speakers do not, does the relay click on when no speakers are connected (or selected), etc. In my experience, it is most often the output transistor(s) in the power amp. But not always ;-)

SOURCE: won't power up; push power button on, hear click in back left of unti, get nothing on front display and no output from speakers; as if unit trying to operate

Disconnect the speakers and see what happens. Carefully examine the speaker cables for unwanted connections (shorts).
Take a clue from when the power problem appeared. Something was moved and made the buzz a (probable) dead short.

Sounds like the volume control on zone 2 is your culpret. You should set up zone 2 to have a "fixed" output instead of "variable" it's in zone 2/3 setup. whats happening is you are overloading the volume control from the zone volume on the receiver and getting feedback to the receiver and shorting it out. What you do is put zone 2 to fixed output. set the vol control to 3/4 then adjust the vol to relatively loud and exit out of settings. this will be your max volume setting. Now, on to your problem.Unplug the receiver. There is an internal fuse that could have blown, not to likely but it's possible. You have to take the top off the receiver with a #1 phillips or a T10 torx they vary. It's about 7 screws, pop off the top and look from front to back, you will see 1 or 2 fuses near the AC plug port. Sometimes they are gray or white and you cannot visibly tell if it's bad. If you have a multimeter, set it tone resistance. Then put your leads on either side of the fuse, if you hear tone the fuse is ok. If not check your leads by touching them together and you will hear tone then test again. If you don't have tone, your fuse is bad. Radio Shack should stock the fuse you need. If you don't already know this, there are 2 Power switches for your unit. Front of receiver bottom left corner "Master Power" and normal Power switch "Main Power" check them both. If your fuses are good and power is good, you have bad transistors internally and it needs to go to service. check www.yamahausa.com support and service, and you can find the closest authorized service center to send it to. If you mail it out directly to the service center rather than taking it to a dealer, you will save some money and get it back faster. Lastly, pull your zone 2 volume control and look for black marks on it or white chalky substance. "oxidation". If you don't mind spending a little money on the system, hardwire the speakers thru and replace the volume control with an IR receiver. If you could control the zone from the zone by pointing the remote at the volume control you had an IR vol control. You really didn't need the vol part. Xantech or Proficient make good IR receivers that aren't too expensive and will keep this from happening again. If you need any more help, I am a Yamaha Dealer, let me know where your located and I can send you to a good service center. Just post a comment and I'll get you the info you need. Hope this helps

This sounds like a thermal issue, meaning after the receiver has been on for a while it gets to warm and then fails. I suspect after 8 years the unit may have accumulated some dust that is not allowing the heat sinks to dissipate heat adequately. I would use compressed air and blow the unit out. Some computer stores have blow stuff in a can that work well. If you have and air compressor, dial it back to 10 psi or so. You will be amazed at how much dust will come out of that unit so you may want to unhook the unit and take it outside. Also be careful not to stack anything on top of your receiver. Make sure there are lots of openings around the unit. High temperatures kill electronics.
Hope this helps.

• To make a diagnosis
1. Timer LED start to blink and the unit automatically stops the operation.
2. Press the CHECK button on the remote controller continuously for 5 seconds.
3. "- -" will be displayed on the remote controller display.
Note: Display only for "- -". (No transmitting signal, no
receiving sound and no Power LED blinking.)
4. Press the "TIMER" or button on the remote controller. The code "H00" (no abnormality) will be displayed and signal will be transmitted to the main unit.
5. Every press of the button (up or down) will increase abnormality numbers and transmit abnormality code signal to the main unit.
6. When the latest abnormality code on the main unit and code transmitted from the remote controller are matched, power LED will light up for 30 seconds and a beep sound (continuously for 4 seconds) will be heard. If no codes are matched, power LED will light up for 0.5 seconds and no sound will be heard.
7. The breakdown diagnosis mode will be canceled by pressing the CHECK button continuously for 5 seconds or without any operation the remote control for 30 seconds.
8. The LED will be off if the unit is turned off or the RESET button on the main unit is pressed.

Or better yet, get a tech to check first.

How Does a Home Automation System Work?


Methods of Control

  • Components of a home automation system are controlled via various methods, depending on the manufacturer. Systems may be controlled wirelessly or may be hardwired. Wireless methods use radio frequencies like Bluetooth and infrared, while hardwired systems may use ethernet, phone cable, electrical wire or coax cable. Most systems use a mix of wired and wireless components.

Lighting

  • Lighting is handled by inline dimmers, lamp plug-ins and gas fireplace dimmers. Hardwired dimmers and lamp plug-ins are installed between the light and the power source. The dimmers regulate the amount of power sent to the light giving you the ability to adjust the brightness of the lighting. Fire place dimmers work the same way, they allow you to regulate the amount of gas released and control the brightness and mood your fireplace gives off.

Heating and Cooling

  • Replacing your current thermostat with a "smart" thermostat allows you to remotely program when your air conditioning or heating unit operates and what temperatures they maintain. led displaystransparent led screenThermostats can either be programmed to switch on or off at certain times or may be controlled through the internet via an ethernet connection. You can also control it wirelessly via RF signals.

Security

  • Security setups contain a base unit and any number of wireless and hardwired sensors for doors and windows. Sensors are made of two pieces that touch when the door or window is closed. But when the device is separated, by a door or window being opened, the electronic circuit is broken. The sensor reports the breach back to the base unit via radio frequencies. If the base unit is active when the breach occurs, it will sound an alarm and a phone line connection to dial pre-programmed contacts--such as emergency services or your cell phone.

Cameras, Surveillance and Driveway Reporters

  • If you have a driveway reporter, when something passes by and breaks its laser beam, alarm security systemthe length of the break and time of occurrence are reported back to a base unit inside your home via RF signals. Units detect the presence of people and vehicles but ignore animals. Cameras work similarly--they report video data back to a base unit via RF signals. Cameras may also use infrared technology for night vision or compacted circuitry for a smaller size. The base unit for the cameras sends video signals to a monitor, VCR or a hard drive.

I have a goodmans dpl 905 surround sound system and the remote won't operate any function on the base unit. The light on remote is working can it be tuned in with a code.


If you have a Goodmans system and the Goodmans remote that came with it, you should not need a code. Try removing batteries from the remote, pressing all buttons to eliminate a stuck button as a possibility, reinstalling batteries (or installing new ones), and testing operation.

My Sound Space12 powers on but there's no display and no manual or remote functions to operate the discs or the other functions.Can you provide a answer.regards


If the system is connected properly and the main tuner power is on you will see the orange standby light on in the front of the main diamond shaped control unit. If that light is not on, you have not connected the system and power cables properly.

If the standby light is not lit, press the power on/off button in the middle of the rectangular processor/tuner to turn it off and unplug the main power cord from the main tuner/processor from the wall. Next, ensure that all of the power, video and audio cables from the diamond shaped control unit are properly connected to the large tuner/processor. Since you are there, check any other av in/out connections.

Now that you have checked and adjusted the cables between the controller and the tuner, plug the tuner back into the wall and push the power on button. Now check the standby light again on the diamond shaped controller unit.

Once that light is lit, press the silver, horizontal on button in the middle of the diamond shaped display unit, or the Power Standby/On button on your main remote control and you are operational.

My sms3 switches on and shows a red power led. However it does not show up on the control keypads or computer and will not play. Also th cd tray won't open.


This unit is effectively a Red Hat Linux server based on a Via Custom Motherboard. You description is consistent with a unit that does not boot. This can be caused by a number of problems that need to be diagnosed a bit further. Installation of a computer display on the VGA connector will allow you to watch some of the boot process. This may help the informed observer but it will not be obvious to a non computer service tech. Pressing the F1 key may provide more information during the boot but again that may be only useful to the service tech.

Problems to suspect but not a complete list.

Motherboard issues (known that Russound Motherboards by VIA used capacitors that were faulty)
Hard drive has failed, usually need to replace disk (easy) with dd(ed) image of original system (hard).
Portion of the power supply has failed. (red light may be just from 5 volt but 12 volt is gone)

Power off and on again and then no sound present


i assume pressing the source button on the remote control is how you normally turn it on again, (ie video FM CD etc)

it might be that moving the unit to the cabinite the battery power in the remote ( its not infra red its radio wave thay are not picked up by the fm antenna ) is insufficient to wake it up again,
change the batteries in the remote or try to see if there is some weird reason the cabinet is preventing these remote control radio waves from being recieved by the head unit, try opening the door and bring the remote within a few inches of the head unit and see if it turns on when you pres the cd button.

see how you go from there mate
