Why is my volume knob stuck at one volume?
My OP-1 Just stays at one volume. The knob that controls the volume stays at the loudest even if I turn it all the way down. Not totally sure what to do, or how to repair.
I had the same issue from time to time. Also, the power on/off switch was behaving weirdly. After exchanging the connector board, the volume knob failure disappeared aswell. Maybe that helps.
