Troubleshooting
LitePro 560/570 User’s Guide 49
Problem: Image is not centered on the screen
• Use the arrow buttons on the remote to center the image. (The
menu must be off when you re-position the image. When the
menu is displayed, the arrow buttons have a different function.)
Refer to “arrow buttons” on page 21 for more information.
Problem: Only the test pattern is displayed
• Are your cables connected correctly? Check to see that the cable
is connected to the graphics port on the computer (this is the
connector where your monitor cable usually goes).
• Did you turn on the equipment in the correct order? You may
need to repeat the power up sequence. The equipment must be
powered on in this order: LitePro, computer monitor, computer.
It is especially important that this sequence be followed for
Macintosh computers.
• Is your computer graphics system set up correctly? Is your
computer ’s graphics board turned on?
Problem: Image is too wide or narrow for screen
• You may need to adjust the tracking to reduce or enlarge the
projected image. Refer to “Tracking” on page 33 for more
information.
• You may need to adjust the resolution of your monitor if it is
greater than 800x600 pixels. Otherwise, your presentation display
may appear overly compressed.
Problem: Image is out of focus
• Turn the projection lens to focus the image.
• The projection screen must be at least 4 feet (1.2m) from the
LitePro.
• The projection lens may need cleaning.
Problem: Remote not operating correctly
• You may need to replace the batteries in the remote. Refer to
“Replacing Batteries in the Remote Control” on page 42 for
instructions.
