I have a matrantz 2238B every few minutes one channel goes silent- then if I click on another component (the cd player)- it goes on again- then off a few minutes later- strange? indeed!

Hi blast2

The old girl will have some noisy switch contacts in the signal path somewhere. Every time the fault comes on, check carefully check each source switch, vol control, tape monitor, speaker switches.and a pre out main in switch n the back if I remember correctly. check these first and see how you go. A noisy switch can be fixed simply with a squirt of crc 2-26 spray.

It appears they may have the schematics and manual for the unit which will allow you to get a list of the parts which you can then find the specific parts you need online or at your local hardware store.

No sound from front left channel


Hi, here is a procedure to discover the source of the problem. No sound from the left front channel can have several sources other than the left front channel itself.
Let's assume, for just now, that the speaker is good and the cable to it is good.
Here is a testing sequence to follow:
1 If you have a CD player connected to it. Put a CD in and put it into play mode.
2 reverse the connectors from the CD player to the receiver. See if the sound moves to the left speaker and stops on the right speaker. Or if it plays fine.
3 If the sound reverses channels, That cable is bad. Replace it
4 If the sound is still not coming from the left channel. Check the connections and cables to the speaker. MAKE SURE THERE ARE NO STRANDS OF WIRE TOUCHING THE CHASSIS OR SHORTING TO THE OTHER SPEAKER WIRE.
5 If there were. Correct it. Shut down the receiver and then after a few minutes turn it back on.
6 If it still does not work. check to see if a tiny amount of sound is coming from the left speaker.
If so, turn the music up and see if it pops back on . If that is the case there is a failed resister on the circuit board that is arcing when you turn up the volume. That being the case, it is time to drop off the receiver to be repaired in the service center.
Hope this helps,
Best,
Mark

About 8 months old...one channel does not work...I've tried speakers and headset, one channel silent on both... we've had lightening storms, I'm on a surge protector, is it a fuse or a button I need to...


Did problem happen suddenly, or did the sound fade out slowly over time. Either way, this is not a fuse or button problem. Sometimes the volume knob will fail and you will hear sound from only one channel. May be able to order a new volume knob component.

Center channel goes muffled after a while of use.


It is likely that something overheating is causing the problem, but nothing should be overheating. Cleaning won't hurt and may help but it is likely to require repair of the faulty component, perhaps a failing capacitor or amplifier.

Kenwood Receiver KR-V127R - left channel not working


Select an input that is not connected, for example select CD with no cables going to the CD input on the backside. Will you then hear equal humming on both channels? If so, the amp stage is ok,
and the problem lies in the signal level circuitry.
Open the cover and use a plastic (insulated) stick to touch suspectible cables and components. When the sound returns, you've found the cause. Resolder or reseat the component/cable/card.
Use the insulated stick, NOT your fingers!

Distortion/noise and buzz in front left speaker


Try to see if the reciever will make the buzzing/noise without anything connected to it except power, and speakers. Tune into a local radio station and see if the noise continues. If the noise has stopped, then you know there is an issue with the player or cable.

Dvd hookup


No need to play down...many guys are just as untechnical.

Players have three connections. Typically, your tv has similar inputs located on it and plug in goes color to color. Yellow is the video. Red is always the right speaker (on any system). White is the left channel. Insert a known good DVD and press play before you actually do the switchover so you can see it working in the next step. Now...set your TV to component input (it may be TV/Vid on your remote). Your TV manual should tell you how to do this. There may be more than one input...press that button again. It will come through.

If your tv doesn't have these connections, there are similar ones on your VCR...you can 'play through' by setting component input and then getting the VCR to send it on through on a TV channel. Start with the VCR tuning a channel and then switch over to component...Same deal...start the DVD first.
