I have erratic operation of the volume control on my receiver. The volume "jumps" from very low to very loud. It does this BOTH when I rotate the volume knob, and also when I use the remote control. I did clean the contacts inside the volume sensor, and this did help reduce the problem a little. Does anyone know of any other possible causes of this problem? Thanks!
A VolControl can be either optical OR electro/mechanical........
If it is optical, a spritz of something like deoxit may make things worse.
If it is electro/mechanical, some contact cleaner should have fixed it. When doing such a spritz, have power OFF and work the VC up/down several times to allow the self cleaning action to do so.
If this doens't fix it.....I'm afraid you need to seek 'professional help' in the form of a tech. Not cheap, but depending on the value of the piece, worth it.
Ditto. Don't get into your amp's innards unless you know exactly what you are doing and why. Leave this work to a tech, it's worth the few bucks it will cost.
