When I connect the power chord and switch on from the back there is a
yellow led near the front panel power button.

If I press this button a green led shows up but disappears after about 3
seconds and the yellow one comes back. Nothing shows up on the screen.

Is it a stupid trouble I can fix myself? (internal fuse or similar)

Manual he

Page 31 addresses your concerns.

Generally, reading the manual for a complex piece of equipment can be helpful. I have been known to do it myself!

Thanks for the manual, but I am not learning much.

This sythetizer had spent a few years on a shelf. After a few days with
the 220 V it restarted. I believe some accumulator was empty and it is
unable to boot in this case.

Hope it may help someone in the future :-)

I am unclear whether it started (properly) after a few days, or it remains on standby mode?

Present tense?

Yeah. Actually reading a manual is typically my last resort.

Do you mean synthesizer?

It started properly.

I believe some accumulator was empty and I believe it is unable to boot when
this accumulator is empty.

There may well be some sort of rechargeable battery (apparently referred
to as an accumulator in the EU) for the CMOS memory in this tool that
requires enough charge to retain settings and when discharged won't
allow normal booting. I would open the device to make sure the battery
is not a Ni-Cad style and thus avoid the risk of battery leakage eating
your circuit boards...
The manual only states there is some kind of battery/accumulator in the
device but doesn't say what type it is - Ni-Cad, Lithium, etc.
