Roland sp540v

My sp540v won't power up. The three lights on the outside, only the right green is on steady. The main board also has a green steady light. I'm confused. Anyone with suggestions would be greatly appreciated.
Thanks..

Is most likely the control panel as we discussed previously. The printer itself is getting power fine or the main board wouldn't light up

I replaced the control panel board with a known good one. Still the same result................

Did you replace the cable from the control panel to the mainboard as well as these can often go and give a fault as well.

Yes

OK in that case it would point to your main board failing. Even though it is getting power it doesn't seem to be booting up
