Alesis Andromeda A6

Greetings all.

This is my first post here after being a silent member for quite a while.

I have a chance to obtain an Andromeda with a fault/fault(s).

To quote the seller - "The issue is that the all of the knobs have just stopped functioning... all sounds and menu's normal but no tweeking!"

Could the issue be an internal front panel connector cable that needs re-seating?
Or a circuit relating to scanning the front panel controls at fault?


Thanks.
Michael.
