Kenwood receiver sound cuts out

Just found this forum today, hopefully someone can point me in the right direction. I have a Kenwood stereo receiver, model KR-A5030. Quite often when I play a CD or DVD, the sound will cut out in one channel, usually the right. Jiggling the volume control will fix it, but I'm not convinced the problem is there, since adjusting some other controls will fix the problem also. This seems to happen more a lower volumes, such as listening to the TV through the stereo. At higher volumes, such as playing a CD to be heard throughout the house, the problem doesn't happen nearly as much. Any ideas on where to start diagnosing the problem?

the volume control and balance can cause this problem. the shafts develope carbon paths to gound.the controls internal paths get dirty with carbon.take wd40 pull out knobs squirt gently twist control back and forth and see if problem fades away.you migth have to do lets say twice.if more change controls.repaired tv stereo appliances 31 yrs ran into this alot.

I'll give that a try. Thanks.

Hi, There
I've the same problem before on this old machine and I finally found the solution to it. It is caused by the bad contact inside the relay of output stage. You can open the case, looking for two black box on the left circuit board. When you found the sound is off, you can tap that two boxes and then sound should be back. If this really true, you can open that black box (about 1x3x2
cm cube). Give WD40 to clean up its metal contact then the problem should gone.

Hope this help
