When you say Tune One works, are you referring to the auto-tune function, or
to the slider function when the LED is on? If you can turn on the TUNE LED
and get plus-or-minus one semitone of master tuning range with the slider,
then the slider is fine.

If the slider itself still works, the only failure I can imagine which would
leave the volume on at a fixed level is a failure on the output board, such
as a short in transistor Q1. Is the volume at maximum, normal, or soft? Did
the master volume work properly before, or is this a unit you just bought,
and it's never worked for you? Or are you fixing someone else's Polaris?
