Check to see if the projectors have their RED standby lights on (if not, then there is no power from the outlet).
Try turning the projector on from the power button on the unit itself.
Check the WARNING indicator on the unit- if it lights up, the projector cannot be turned on. Refer to manufacturer’s manual.
Check the projection lamp to see if it is damaged (See Section 5 of the Operations and Maintenance manual).
