Software, download the Owners Manual and get into it.

Contact Roland Customer service for a repair center.

I'm pretty sure it in the owners manual...

This problem will require servicing. The screen is bad, and has to be replaced.

The unit name is part of the boot sequence, it should go beyond that and boot up completely. If it gets stuck there, there is surely some problem. Maybe a depleted internal battery, I don't know. Ask a local service center, maybe there's a combination of buttons you could check out while on the phone prior to bringing it in for repair...

I had this problem and was about to send it back to Roland but tried a Factory Reset . It managed to fix it self but it has happened again so I woul dbe interested in finding a more perminnat solution .
Did you fix the probolem?

Most of the Roland buttons on this type equipment use a small switch that is actuated by a plastic button that is HINGED from a plastic panel behind the faceplate or a part of it. These plastic hinges get broken when too much force is applied to the button... it is USUALLY fatal and requires replacement of the whole button faceplate... and they are expensive... contact Roland parts to inquire.
