Riso Comcolor 7150 does not power up

[SimmBuzz]

Hello, my Riso Comcolor 7150 does not power up at all.
The main power lamp is not lit
I checked the fuses in the power suply unit and on the X-3 engine PCB > they are good.
I don't know what to try next.
Any idea ?

Thanks for you help

Hello you are a technician, just to know, look for a used one on the web or take it to a qualified service center, some companies overhaul electronic boards at an affordable price, you will save yourself headaches

Same here. We tried to repair power supply unit, without success.

I resolved changing the board.
