Maintenance and Care
The WARNING indicators show the state of the function which protects the projector. Check the state of the 
WARNING indicators and the READY indicator to take proper maintenance. 
Warning Indicators
The projector is shut down and the WARNING TEMP. 
indicator is blinking red.
When the temperature inside the projector reaches a 
certain level, the projector will be automatically shut down 
to protect the inside of the projector. The LAMP indicator 
turns red and the WARNING TEMP indicator blinks while 
the projector is being cooled down. When the projector has 
cooled down enough (to its normal operating temperature), 
it can be turned on again by pressing the ON/STAND-BY 
button.
✔Note:
	•	 The	WARNING	 TEMP.	indicator	continues	to	blink	even	after	the	
temperature	inside	the	projector	returns	to	normal.	 When	the	
projector	is	turned	on	again,	the	 WARNING	TEMP.	indicator	stops	
blinking.	
Then check the matters below:
–   Did you provide appropriate space for the projector to be 
ventilated? Check the installing condition to see if the air 
vents of the projector are not blocked.
–   Has the projector been installed near an Air-Conditioning/ 
Heating Duct or Vent? Move the installation of the 
projector away from the duct or vent.
–   Is the filter clean? Clean the filter.
CAUTION
DO NOT LEAVE THE PROJECTOR WITH THE 
AC POWER CORD CONNECTED UNDER AN 
ABNORMAL CONDITION. IT MAY RESULT IN FIRE 
OR ELECTRIC SHOCK.

READY
The projector is shut down; and the LAMP indicator is 
lighting and other indicators are blinking.
When the projector detects an abnormal condition, it 
will be automatically shut down to protect the inside of 
the projector and the LAMP indicator lights on and other 
indicators blink. In this case, unplug the AC power cord and 
plug it, and then turn on the projector once again to verify 
operation. If the projector cannot be turned on and these 
indicators are still lighting and blinking, unplug the AC power 
cord and contact the service station.

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.
