Common problems and solutions

These guidelines provide tips to deal with problems you may encounter while using the projector. If
the problem remains unsolved, contact your dealer for assistance. Often the problem is something
as simple as a loose connection. Check the following before proceeding to the problem-specific
solutions.
• Use some other 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 suspend mode.
• Ensure a connected notebook computer is configured for an external display. (This is usually
done by pressing an Fn-key combination on the notebook.)

Tips for troubleshooting

the problem more quickly.
Try to pinpoint the problem to avoid replacing non-defective parts.
