Blank screen in settings

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   While attempting to change settings on my (brand new) 540, the screen went completely blank.  Would not respond to any input, button pushes, etc.  Had to restart it to get anything back on the screen. Happened several times.  I was initially attempting to change the lighting schedule.  Thought maybe it had gone dark via the photocell, so I set it to manual lighting, tried again, same thing happened.  I eventually tried other settings, and was finally able to get back to and set the lighting schedule. 

What might have caused this?  A malfunction, or something not set correctly?

	So the IFD was readable, then you went to maintenance mode to adjust the lighting configuration. You did something there and then the screen went dark? What else did you try that finally caused the brightness to increase?
