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 from 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 37.
• Make sure that the CablePro and the cables do not have any
bent pins. Check the power cord for bent pins also.
Problem: Color or text not being projected
•
You might need to adjust the brightness up or down until the
text is visible. Refer to “Brightness + or -” on page 22 for more
information.
• Verify that the appropriate input source is selected. See “Com-
puter” on page 22 or “Video” on page 23.
Problem: The screen resolution is not right
•
Make sure the computer’s graphics card is set for a resolution
of no greater than 1280x1024.
Problem: Image isn’t centered on the screen
•
Reposition the image. Refer to “Horiz. Position” on page 30
and “Vert. Position” on page 30.
• If you’re using an extension cable between the CablePro and
the projector, make sure it’s Boxlight-approved.
