Troubleshooting
Before calling your dealer or service center for assistance, check the items below once again.
1. Make sure you have properly connected the projector to peripheral equipment as described on pages 20–21.
2. Check the cable connection. Make sure that all computers, video equipment, and power cords are properly
connected.
3. Make sure that all power is switched on.
4. If the projector still does not produce an image, restart your computer.
5. If an image still does not appear, disconnect the projector from your computer and check your computer
monitor’s display. A problem may be noticed with your graphics controller rather than with the projector.
(When you reconnect the projector, be sure to turn the computer and monitor off before you turn on the
projector. Turn on equipment in the order of the projector and computer.)
6. If a problem still persists, check the following solutions.
No power.
● Plug the power cord of the projector into the AC outlet.
● Wait until the POWER indicator stops blinking to turn on the projector again. (See page
23)
● Check the WARNING TEMP. indicator. If the WARNING TEMP. indicator is blinking, the
projector cannot be turned on. (See page 63.)
● Check the projection lamp. (See page 59.)
● Unlock the Key lock function for the projector. (See page 53)
● See if the filter cartridge is inserted. (See page 57)
Image is out of focus.
● Adjust the focus of the projector.
● Make sure the projection screen is at least 4.6’ (1.4 m) away from the projector.
● Check the projection lens to see if it needs cleaning.
NOTE: Moving the projector from a cool to a warm place may result in moisture
condensation on the projection lens. If this happens, leave the projector off and
wait until condensation evaporates.
