Problem Check These Items
Does not turn on or shut
down
• Check that the power cord is plugged in and that the power button on the projector cabinet or the remote control is on.
(→ pages 19 and 20)
• Ensure that the lamp cover is installed correctly. (→ page 83)
• Check to see if the projector has overheated. If there is insufficient ventilation around the projector or if the room where
you are presenting is particularly warm, move the projector to a cooler location.
• Check to see if you continue to use the projector for another 100 hours after the lamp has reached the end of its life. If
so, replace the lamp. After replacing the lamp, reset the lamp hours used. (→ page 79)
• The lamp may fail to light. Wait a full minute and then turn on the power again.
• Set [FAN MODE] to [HIGH ALTITUDE] when using the projector at altitudes approximately 3000 feet/900 meters or higher.
Using the projector at altitudes approximately 3000 feet/900 meters or higher without setting to [HIGH ALTITUDE] can
cause the projector to overheat and the projector could shut down. If this happens, wait a couple minutes and turn on the
projector. (→ page 70)
If you turn on the projector immediately after the lamp is turned off, the fans run without displaying an image for some
time and then the projector will display the image. Wait for a moment.
Will turn off
• Ensure that the [OFF TIMER] or [AUTO POWER OFF] is off. (→ page 65, 73)

• Use the COMPUTER 1, the COMPUTER 2, the VIDEO or the S-VIDEO button on the remote control to select your source
(Computer, Video or S-Video). (→ page 22) If there is still no picture, press the button again.
• Ensure your cables are connected properly.
• Use menus to adjust the brightness and contrast. (→ page 58)
• Remove the lens cap.

• Enter your registered keyword if the Security function is enabled. (→ page 34)
• Be sure to connect the projector and notebook PC while the projector is in standby mode and before turning on the power
to the notebook PC.
In most cases the output signal from the notebook PC is not turned on unless connected to the projector before being
powered up.
* If the screen goes blank while using your remote control, it may be the result of the computer’s screen-saver or power
management software.

comes dark
• Check if the projector is in the Forced ECO mode because of too high ambient temperature. If this is the case, lower the
internal temperature of the projector by selecting [HIGH] for [FAN MODE]. (→ page 70)

happen, let the projector stand until there is no condensation on the lens.
Flicker appears on screen
• Set [FAN MODE] to other than [HIGH ALTITUDE] mode when using the projector at altitudes approximately 3000 feet/900
meters or lower. Using the projector at altitudes less than approximately 3000 feet/900 meters and setting to [HIGH
ALTITUDE] can cause the lamp to overcool, causing the image to flicker. Switch [FAN MODE] to [AUTO]. (→ page 70)
