Maintenance & Troubleshooting

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.

Check cable connections. Verify that all computer, CablePro

and power cables are properly connected.

Verify that all power is switched on.

Verify that the projector has not been switched off with the

standby

button on the keypad.

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.

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.

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 53 for more information.

If the problem still exists, read through the problems and solu-

tions in this chapter.
