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 after time spent troubleshooting, the problem is traced to 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  suspending 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  Troubleshoot ing 
In  each problem-specific section, try the steps in the order suggested. This may help you to solve the 
problem more quickly. 
Try to pin point the problem and thus 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.
