Good evening I am attaching a picture of the only place that we have switches that I can find. No clue why it is not working.
With the power on, loosen one at a time, each of the fuse holders and see and listen for any changes. You should hear speaker crackle, you can see lights come on/off but you should also ear different hums. Check that each fuse has some sort of change in the machine.
Also, is your candles showing anything?
Did you run optic tests or switch out optics?
Need to figure out if your machine is recognizing the main door being closed.
