Filter Instructions
Filter prevents dust from accumulating on the optical elements inside the projector. Should the filter becomes 
clogged with dust particles, it will reduce cooling fans’ effectiveness and may result in internal heat buildup 
and adversely affect the life of the projector. This projector has an electrically operated filter which helps you to 
replace the filter easily. The projector monitors the condition of the filter at all time and replaces a filter with a 
new one automatically when it detects the clogging. 
If the projector reaches a time set in the timer setting (p. 
60), a Filter replacement icon (Fig.1) appears on the screen 
and the WARNING FILTER indicator on the top panel lights 
up (p.77). When you see this icon, replace the filter as soon 
as possible (pp.33, 55). If the filter is out of scroll and the 
projector reaches a time set in the timer setting, Fig. 2 
appears on the screen, indicating that the filter cartridge 
replacement is necessary.
When the filter scroll is counted down to 1, the Last scroll 
icon (Fig.3) appears on the screen, indicating that there is 
one scroll left in the filter cartridge (p.60).
If the projector detects that the filter is clogged and no scroll 
is left in the filter cartridge, a Filter cartridge replacement 
icon (Fig. 4) appears on the screen and the WARNING 
FILTER indicator on the top panel lights up (p.77). When you 
see this icon, replace the filter cartridge (p.62) and reset the 
Filter counter (p.63) and the Scroll counter (p.63).
When the filter is being scrolled using the remote control 
(p.33) or the Filter control function in the setting menu 
(p.55), a Filter replacement icon and “Please wait...” 
message (Fig.5) appear on the screen and the WARNING 
FILTER indicator blinks slow (approx. 2 seconds ON, 2 
seconds OFF) (p.75).
The WARNING FILTER indicator blinks fast when the 
projector detects an abnormal condition, the filter cartridge 
is not installed properly, or the filter scroll is not working 
properly (p.77).

RECOMMENDATION
We recommend avoiding dusty/smoky environments when 
operating the projector. Usage in these environments may 
cause a poor image quality.
When using the projector under dusty or smoky conditions, 
dust may accumulate on a lens, liquid crystal panels, or optical 
elements inside the projector. Such condition may degrade the 
quality of the projected image.
When the symptoms above are noticed, contact your authorized 
dealer or service station for proper cleaning.

This projector uses a high-pressure lamp which must be handled carefully and properly. 
Improper handling may result in accidents, injury, or create a fire hazard.
L Lamp lifetime may differ from lamp to lamp and according to the environment of use. There is no 
guarantee of the same lifetime for each lamp. Some lamps may fail or terminate their lifetime in a 
shorter period of time than other similar lamps.
L  If the projector indicates that the lamp should be replaced, i.e., if the LAMP REPLACE indicator lights 
up, replace the lamp with a new one IMMEDIATELY after the projector has cooled down. (Follow 
carefully the instructions in the Lamp Replacement section of this manual.) Continuous use of the lamp 
with the LAMP REPLACE indicator lighted may increase the risk of lamp explosion.  
L Lamp may explode as a result of vibration, shock or degradation as a result of hours of use as its 
lifetime draws to an end. Risk of explosion may differ according to the environment or conditions in 
which the projector and lamp are being used.
IF A LAMP EXPLODES, THE FOLLOWING SAFETY PRECAUTIONS SHOULD BE TAKEN.
If a lamp explodes, disconnect the projector’s AC plug from the AC outlet immediately. Contact an 
authorized service station for a checkup of the unit and replacement of the lamp. Additionally, check 
carefully to ensure that there are no broken shards or pieces of glass around the projector or coming out 
from the cooling air circulation holes. Any broken shards found should be cleaned up carefully. No one 
should check the inside of the projector except those who are authorized trained technicians and who 
are familiar with projector service. Inappropriate attempts to service the unit by anyone, especially those 
who are not appropriately trained to do so, may result in an accident or injury caused by pieces of broken 
glass.

							67User's Manual
020-000119-01
Unplug the AC power cord before cleaning.
Gently wipe the projection lens with a cleaning cloth that 
contains a small amount of non-abrasive camera lens 
cleaner, or use a lens cleaning paper or commercially 
available air blower to clean the lens. 
Avoid using an excessive amount of cleaner. Abrasive 
cleaners, solvents, or other harsh chemicals might scratch 
the surface of the lens.
Cleaning the Projector Cabinet
Unplug the AC power cord before cleaning.
Gently wipe the projector body with a soft dry cleaning 
cloth. When the cabinet is heavily soiled, use a small amount 
of mild detergent and finish with a soft dry cleaning cloth. 
Avoid using an excessive amount of cleaner. Abrasive 
cleaners, solvents, or other harsh chemicals might scratch 
the surface of the cabinet.
When the projector is not in use, put the projector in 
an appropriate carrying case to protect it from dust and 
scratches.

The WARNING indicators show the state of the function which protects the projector. Check the state of the 
WARNING indicators and the POWER 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/SHUTTER 
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.

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? Replace the filter with a new one.
The projector is shut down; and the LAMP/SHUTTER indicator 
is lighting red and other four 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/SHUTTER indicator lights red and 
other four 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.
CAUTION
DO NOT LEAVE THE PROJECTOR WITH THE 
AC POWER CORD CONNECTED UNDER AN 
ABNORMAL CONDITION. IT MAY RESULT IN FIRE 
OR ELECTRIC SHOCK.

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 22–24.
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.
Appendix
