Masso Elite Screen Blacking out

I have had my Elite since they first came out and in the last few days having issues with the screen going to all vertical lines or just black unresponsive, I restart it and it works again.
Anybody have similar issues?
Thanks, Pat

Mine just went all black during a job. Nothing out of the ordinary. Just stopped in its tracks with a black screen and the spindle spun down. The only sign of life I can get is when I turn it off and back on the (z?) axis locks. The three fuses are all good.
