Troubleshooting
LitePro 760 User’s Guide 37
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 19 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? Check the
following:
- Is your computer’s graphics board turned on?
- If your computer has an external video board, is it turned on?
- Does your computer have a compatible graphics board? The
LitePro 760 is not compatible with CGA and EGA graphics.
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 “Track” on page 23 for more
information.
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.
