Question about Yamaha RX-V690 Receiver

2 Answers

No output - After powering on, the normal momentary delay occurs and I hear the relay kick in. - Muting and canceling mute to ensure muting was off. - All front panel and all remote functions are working (radio tuning, DSP, etc.). - Selecting front and/or rear speakers does not matter. - No headphone output - Removed the three fuses and all ohm out ok. - After powering off for a while, the unit sometime produces only static output to the speakers, most times it does not. - Tried all inputs from CD, Tape, Aux, VCR1, and LD/TV (cable/dvr), all of which were previously operating fine. - No components appear to be burnt, etc.

    Thank you for your quick response and suggestions, however I do not have the schematics and thus unable to determine locations and what the voltage levels should be.

We have just purchased a Samsung Smart TV - we have the Sennheiser RS116 headphones - they are working with the TV but when you put the TV on mute they do not mute. Is their anyway I can get them to mute....


On your old TV, the headphones connected to the internal speaker output so muting the TV also muted the headphone output. Your new TV headphone circuit connects elsewhere to provide constant output regardless of mute selection.

Why does my pioneer vsx-d557 automatically go into MUTING WHEN I turn it on?


Maybe you have MUTING selected. Turn the volume knob up or toggle the Mute control on the remote.

If it defaults to muting on power up find the manual and search it for a default volume setting.

My amps stays in the clip mode where as the light on the two channel stays red


http://www.retrevo.com/support/QSC-RMX-4050HD-Amps-manual/id/23107ci658/t/2/

Page 7...

CLIP: red, to the left of each Gain control.

Normal indication: illuminates whenever the amplifier is driven beyond full power. The LED's brightness indicates the amount of distortion. Distortion that causes only brief flashing may not be audible.

During muting, the indicator fully illuminates. This occurs during normal "On-Off" muting.

Abnormal indication:

•Bright red illumination while the amp is being used indicates either thermal muting or a shorted output.

•If the amplifier overheats, the fan will run at full speed, and operation should resume within one minute. Allow the fan to run, and make sure the amplifier ventilation is adequate.

•A shorted or overloaded output circuit will cause excessive Clip flashing and possible overheating.

•If distortion is audible without a Clip indication, the problem is either before or after the amplifier. Check for damaged speakers or overloaded signal source. The amplifier Gain control should be in the upper half of its range to prevent input overload.

Auto muting on when on am/fm and no sounds come out. everything else is fine.


That's normal.

The Auto Muting mode mutes the audio output of the tuner if the station is not sufficciently strong to be accurately tuned. Otherwise you would hear all that interstation hash noise.

Press the FM Mode button to change it to Mono if you want to manually tune a hard-to-reach station. It will be in Mono.

Page 26:

AUTO MUTING
Normally select this.
When a program is broadcast in stereo, you will hear stereo sound; when in monaural, you will hear monaural sound.
This mode is also useful to suppress static noise between stations. The AUTO MUTING indicator lights up on the display.

Muting engaged on power up


This not muting, but protect mode. This means that a problem was detected internally and the unit has shutdown to prevent further damage. The most common cause of this is a failure of the output transistors. Expect a parts cost inthe $20-40 range for this repair.

Hi, I have a NAD 3020 and usable volume has gone. You can still hear it really quietly even with the volume up full. Do you think this is a power transistor or a transformer problem. Cheers. Doug


It's a muting problem, not a power amp problem. The muting circuit on this amp has a very high impedance node, which makes it very sensitive. Right next to the area of the board that contains the muting circuit is a large-ish capacitor that is held in place by a blob of glue. The glue has usually spread out enough to reach some of the muting components. The glue decays over time and becomes slightly conductive. This is enough to keep the amplifier in the muted state, permanently, instead of releasing it about two seconds after power-on.
The picture shows the amplifier with the top removed. The box is where the old glue used to be. The glue is to hold the purple tubular capacitor steady. It is not really necessary unless you have the amp sat on top of your speakers (not recommended).
To remove the glue, unplug the amp from the mains, remove the lid (six screws), locate the area in the picture and scratch the glue away with a large needle or tiny screwdriver. The most important bit is to remove the glue from the bare wires at the ends of the resistors (the brown stripy things).
If this doesn't solve the problem, or it returns, the capacitor that determines the length of the muting period may have failed. This is a slightly less diy repair as you will need a soldering iron and a new capacitor.

System echos when dvd is in. When I mute the Bose sytem I can hear the TV sound without the echo.


The echo you hear is the audio delay between your TV speakers and Bose speakers. Muting (or lowering the volume) on the TV will eliminate the echo. Some TVs have a setting to turn of TV speakers entirely, allowing you to listen to your TVs audio strictly through your Bose system.
