Due to dust or so, the Volume Control Wheel does not work properly. Volume goes to one speaker, and other gets muted. Vice versa. When I carefully turn the wheel sometimes the Volume works properly or sometimes with noise or muted one side.
As I write this, I've cleaned it up with Petrol drops. PCB is drying. I chose Petrol because Contact Cleaner is expensive solution. Am I correct or any other method could be used?
