Often the problem is traced to something as simple as a loose connection. Check the following before
proceeding to problem-specific solutions.
• Use another electrical device to confirm that the electrical outlet is working.
• Ensure the projector is turned on.
• Ensure all connections are securely attached.
• Ensure the attached device is turned on.
• Ensure a connected PC is not in standby mode.
• Ensure a connected notebook computer is configured for an external display.
(This is usually done by pressing a Fn-key combination on the notebook. Go to
www.infocus.com/support and the Learn tab to review the Laptop Activation chart.)
