The wipers inside the sliding controls for treble, bass and balance fall apart in these, if the balance one breaks then this is what can happen. The chassis is fully modular, so you can swap the two power amplifier units over if you suspect that the fault may be in that area, but the sliding controls are the main offenders. You can fuse the wipers back in place into the plastic if that is the cause, it's tricky but not impossible.
