That is called LED test and requires the IN and OUT button to be pressed.

1. Yes.

2. By itself? You wrote you press the Out button, so maybe the In button is pressed all the time (mechanically  blocked)? Does that button work at all?

Simple trick: use two credit cards slided under the big knob left and right. This way it is easy to lift the knob off. Then the PCB will be free as well.

Re: lights up when pressing OUT button

It was not necessary to open another thread. The unit obviously has an electrical problem and you need a technician to figure this out - or send it in for service. This is NOT a firmware or Mac/Windows problem.
