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-specic
solutions.
• Use some other electrical device to conrm 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 congured for an external display. (This is usually
done by pressing an Fn-key combination on the notebook.)
Tips for troubleshooting
In each problem-specic section, try the steps in the order suggested. This may help you to solve
the problem more quickly.
Try to pinpoint the problem to avoid replacing non-defective parts.
For example, if you replace batteries and the problem remains, put the original batteries back and
go to the next step.
Keep a record of the steps you take when troubleshooting: The information may be useful when
calling for technical support or for passing on to service personnel.
