Solutions to Common Problems
Problem: Nothing on projection screen
Make sure that the power cord is properly connected to a func-
tional AC electrical outlet. Make sure that the power cord is 
also properly connected to the projector.
If the projector is plugged into a power strip, make sure the 
power strip is turned on.
Make sure you have removed the lens cap on the projection 
lens at the front of the projector.
Make sure the projector is switched on.
Check the projector’s lamp to ensure that it is securely con-
nected in the lamp module. See “Replacing the Projection 
Lamp” on page 43.
Check the fuse. If it has blown, replace it. See “Replacing the 
Fuse” on page 45.
Make sure that the CableWizard and the cables do not have 
any bent pins. Check the power cord for bent pins also.
Problem: Color or VGA text not being projected
You might need to adjust the brightness up or down until the 
text is visible. Refer to “Brightness” on page 29 for more infor-
mation.
Verify that the appropriate input source is selected. See “Com-
puter” on page 29 or “Video” on
 page 31.
Problem: The screen resolution is not right
Make sure the computer’s graphics card is set for a resolution 
of no greater than 800x600 for the 210, 1024x768 for the 220.
Problem: Image isn’t centered on the screen
If you’re using an extension cable between the CableWizard 
and the projector, make sure it’s In Focus-approved.
