 “Power/Status/Lamp Indicator” on page 

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. (

•  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.

•  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 1200 meters/4000 

feet or higher. Using the projector at altitudes approximately 1200 meters/4000 feet 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. (

  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.

•  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.

•  Set [FAN MODE] to other than [HIGH ALTITUDE] mode when using the projector at altitudes approximately 

1200 meters/4000 feet or lower. Using the projector at altitudes less than approximately 1200 meters/4000 feet 

and setting to [HIGH ALTITUDE] can cause the lamp to overcool, causing the image to flicker. Switch [FAN 

MODE] to [AUTO]. (
