Hi @figarofigaro
If there's no sign of power i.e no power light and you have checked that the fuse is OK it could be an on/off switch problem or a wiring problem. of course the power light could also be blown.
Here's a the wiring diagram and you can see that when the power on/off switch (#1 on diagram) is operated current should flow down through the power on/off light (#2) and then through the fuse (#3).
So if the light isn't working when the switch is operated it is either a problem with the power cord supplying power to the machine, the on/off switch, the on/off light (although this shouldn't stop the machine from working if it was just a blown light) or the wiring between all of them.
''To test safely'', ''disconnect the power cord from the wall outlet'' and then use an Ohmmeter to check the circuit from the power cord plug line (or active pin) right through the switch to the lamp.
If the switch is faulty i.e. no continuity when operated then search online for DM1475 to find suppliers that suit you.
