How to troubleshoot problems with projectors not starting or displaying content
If the system starts up but the projector doesn't seem to come on, check if the projector lamp is on.
Do this by looking at the projectors lens **DO NOT STARE INTO THE LENS**. If the lamp is on, you should see some light coming through the lens even if there is nothing displayed. (This works for almost all projectors)
Check the warning/display lights on the projector, the projector or display may have be accidentally powered off or the lamp may have gone out.
If the system is controlled by a touch panel, look for the control panel's menu to manually turn on the projector or display.
