Question about Audio & Video Receivers
In addition to blowing off a ll the dust and debris from where it doesn't belong, spray a liberal amount of (plastics safe) contact cleaner on all the points of contact inside for the switches and knobs (look for anything moving when fiddling the knobs and switches, there are often lubrication ports in the thingies. Then jimmy the switches and knobs through their full range of motion about 25-30 times. Then repeat with a (plastics safe) silicon based lubricant.
