Hi I got hold of a used 2100MP, but it does not work. It would be really nice if I could get it to work.

When I press the power button nothing happens. I tried to change the fuse but it did not help. I have checked with a simple voltage stick and it shows that it has power on several places including the cable to the circuit board with the power button.

Does anyone have any tips on what might be wrong?

What is the volt/amp output of the power supply? Would it be possible to use another power supply if the voltage/amp matches?
