Problem

Check These Items

 

 

Does not turn on

• Check that the power cord is plugged in and that the power button on the projector cabinet or the remote control

or shut down

is on. (pages 15, 16)

 

• Ensure that the lamp cover is installed correctly. (page 122)

 

• 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 120)

 

• 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 5500 feet/1600 meters

 

or higher. Using the projector at altitudes approximately 5500 feet/1600 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 87)

 

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.

source (Computer, Video or S-Video). (page 18) 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 76)

 

• Ensure that the lens cover is open. (page 7)

 

• Reset the settings or adjustments to factory preset levels using the [RESET] in the Menu. (page 97)

 

• Enter your registered keyword if the Security function is enabled. (page 32)

 

• 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.

or power management software.
