The projector is turning on, but I can’t see any image or the screen in blank.

It takes about 30 seconds for images to appear upon turning a projector on

See if images are present on the other projectors; if so, there could be an operational problem with the unit in question.

If you cannot get images on any projector, try restarting the main 4D PC by selecting ‘Restart’ from the Windows ‘Start’ menu.
