The galley screen works every time. The flight info screen in the cabin. Most times I walk back there and it’s black ( not on) .

This is on the 650 challenger

I have x plane 12 window. The screen in the back has come on a few times. But I’m not sure how I did it. I follow the check lists. Have made many successful flights. Some with the screen working most of the time not. If anyone know how to turn this on I would appreciate it. thanks, Brad
