Troubleshooting
If you’re experiencing trouble with the projector, follow these
steps to make sure everything is properly connected before you
call Technical Support for assistance.
1
Check cable connections. Verify that all computer, CablePro
and power cables are properly connected.
2
Verify that all power is switched on.
3
Verify that the projector has not been switched off with the
standby
button on the keypad.
4
If the projector still doesn’t display an image, restart the com-
puter.
NOTE: Macintosh computers
require a specific power-up
sequence: the projector must be
turned on before you turn on the
computer.
5
If the problem still exists, unplug the projector from the com-
puter and check the computer monitor’s display. The maxi-
mum resolution that the projector can display is 1280x1024
pixels, preferably 1024x768. The problem might be with the
graphics controller in your computer rather than with the pro-
jector. When you reconnect the projector, remember to turn
the computer and monitor off before you power up the projec-
tor. Power the equipment back up in this order: projector,
monitor, computer.
6
If you’re using a laptop computer and it is not displaying your
presentation, make sure you have activated the computer’s
external video output. Most laptop computers do not auto-
matically turn on their external video port when a secondary
display device such as a projector is connected. Refer to
page 51 for more information.
7
If the problem still exists, read through the problems and solu-
tions in this chapter.
