A few weeks ago I turned it on, but the green light on keyboard blinked two or three times then it died.
What do you think about.
I live in South of Italy, so I will be very glad to know someone who lives in the same zone and is expert in such a type of problem.

Welcome to the forum!

I'm pretty sure that something is wrong with the power supply. The first thing I'd do is to check with a multimeter if all of the voltages are there. There should be +5V, +12V and -12V if memory serves me right.

If not I bet on it that the fault are dried out capacitors. If you know how to solder, that can be fixed for just a few cents worth of components.

And also -5V.
