After 6-7 years of good behavior, my receiver started having what I think is a common problem but one for which I cannot find any reference:
When I switch it on, at low volume, only the right channel can be heard. After I crank it up to -15 or -10 the sound is back at both channels and at any volume.
What would be the cause for this? Is it something that I can fix myself (eg, dusting inside) or does it need service? I could live with this for the moment, but from my experience (with other stereo equipment) this only gets worse.
Thanks in advance
