This is odd and developed out of nowhere.
When volume is turned to 8oclock, the right channel buzzes. Then when moved up to 1oclock the left channel buzzes the left channel stops buzzing and visa versus. The buzzing is much louder if an RCA is plugged in (on any input) nothing on playing
The only thing that did happen was I noticed the volume knob wouldn’t change with the remote. I pulled the knob off and the wires which feed the light (on the knob) had wrapped themselves around the spindle. I can’t see how that would have caused the subsequent buzzing though.
