Remedy
Are images from a port other than the 
[Computer1/Component Video1] port being 
projected?
The only images that can be displayed on an external monitor are those from the [Computer1/
Component Video1] port. The [Computer2/Component Video2] port cannot be used for an external

Remedy
Have you pressed the [Power] button?
Press the [Power] button to turn the power on.
Are all of the indicators switched off?
The power cable is not connected correctly or power is not being supplied. Connect the power cable 
to the projector correctly. sp.31
Alternatively, check the circuit breaker to see if power is being supplied.
Do the indicators turn off and on when the 
power cable is touched?
There is probably a poor contact in the power cable, or the power cable may be defective. Reinsert 
the power cable. If this does not solve the problem, stop using the projector, disconnect the power 
cable from the wall outlet and contact the nearest address provided in the International Warranty 
Conditions section of the Safety Instructions/World-Wide Warranty Terms booklet.

MaintenanceThis section describes maintenance tasks such as cleaning the projector and 
replacing consumable parts.Cleaning
You should clean the projector if it becomes dirty or if the quality of 
projected images starts to deteriorate.
Clean the projectors surface by wiping it gently with a soft cloth.
If the projector is particularly dirty, moisten the cloth with water 
containing a small amount of neutral detergent, and then firmly wring the 
cloth dry before using it to wipe the projectors surface. Then wipe it again 
with a soft, dry cloth.
Use a commercially-available air blower, or use a lens cleaning paper to 
gently wipe the lens.If dust collects on the air filter or the air outlet, it can cause the internal 
temperature of the projector to rise, and this can lead to problems with 
operation and shortening of the optical engines service life.
It is recommended that you clean these parts at least once every three 
months. Clean them more often than this if using the projector in 
particularly dusty environments.Cleaning the Projectors Surface
Cleaning the Lens
CAUTION
Be sure to read the separate Safety Instructions/World-Wide Warranty 
Terms before cleaning.
CAUTION
Do not use volatile substances such as wax, alcohol or thinner to 
clean the projectors surface. These can cause the projector to warp 
and make the coating finish peel off.
CAUTION
Do not rub the lens with harsh materials or subject the lens to shocks, 
as it can easily become damaged.
Cleaning the Air Filters and Air Intake Vent
TIP
If the air filters are broken or if the warning message reappears after 
they have been cleaned, they should be replaced. Replace with a new 
air filter. See Appendices: Optional Accessories. sp.93

MaintenanceReplacing Consumables
This section describes how to replace the lamp and the air filters.
It is time to replace the lamp when:
The message Replace the Lamp. appears on the screen when 
projection star ts..When the Lamp indicator is flashing orange.
The projected image gets darker or star ts to deteriorate.Lamp Replacement Period
A message will be displayed.
Flashing orange
TIP
 The lamp replacement message is set to appear after the following 
periods of time in order to maintain the initial brightness and quality 
of the projected images.
· When used continuously at high brightness: Approx. 1900 hours
· When used continuously at low brightness : Approx. 2900 hours
Brightness Control sp.59
 If you continue to use the lamp after this period, the possibility of the 
lamp breaking becomes greater. When the lamp replacement 
message appears, replace the lamp with a new one as soon as 
possible, even if it is still working.
 Depending on the characteristics of the lamp and on the way it has 
been used, the lamp may become darker or stop working before the 
lamp warning message appears. You should always have a spare 
lamp ready in case it is needed.
 Contact your dealer for a spare lamp. 
						

							86
Maintenance
PROCEDURE
Turn off the projectors power, wait until the cool-
down period has ended and a pip-pip confirmation 
buzzer sounds, and then disconnect the power cable.
The cool-down period lasts for about 20 seconds.
Wait until the lamp has cooled down, then remove the 
lamp cover from the base of the projector.
It takes approximately one hour for the lamp to cool down by 
itself after the cool-down period has finished.
Loosen the lamp cover fixing screw with the screwdriver that is 
supplied with the spare lamp (or your own cross head 
screwdriver).
Then slide the lamp cover straight forward and lift it to remove.Loosen the two lamp fixing screws.
Loosen the two lamp fixing screws with the screwdriver that is 
supplied with the spare lamp (or your own cross head 
screwdriver).
Replacing the Lamp
CAUTION
 If you are replacing the lamp because it has stopped working, it is 
possible that the lamp is broken.
If replacing the lamp of a projector which has been installed on a 
ceiling, you should always assume that the lamp is broken and be 
extremely careful when removing the lamp cover.
 Wait until the lamp has cooled down sufficiently before removing the 
lamp cover. It takes a further one hour after the cool-down
g period 
has finished for the lamp to be cool enough.

local dealer for further advice. If replacing the lamp yourself, 
be careful to avoid pieces of broken glass.Install the new lamp.
Insert the new lamp so that the lamp fits the place correctly and 
once it is fully inserted, tighten the two screws.
Install the lamp cover.
Slide the lamp cover and tighten the cover fixing screws.

TIP
 Install the lamp securely. If the lamp cover is removed, the lamp 
turns off automatically as a safety precaution. Moreover, the lamp 
will not turn on if the lamp or the lamp cover is not installed 
correctly.
 The lamp contains mercury. Dispose of used lamps properly in 
accordance with your local regulations. 
						

							88
Maintenance
The projector has a built-in counter which keeps track of the lamp 
operating time. When the cumulative operating time reaches a certain 
point, it causes the replacement warning message to be displayed. 
Therefore, the counter needs to be reset after the lamp has been replaced 
with a new one. You can do this using the configuration menu.
PROCEDURE
Connect the power cable, turn on the projectors 
power, and then press the [Menu] button.
The configuration menu will be displayed.
Select Lamp-Hours Reset from the Reset menu 
and then press the [Enter] button.Select Yes and then press the [Enter] button.
The lamp operating time will then be reset.
Resetting the Lamp Operating Time
TIP
Do not reset the lamp operating time except after the lamp has been 
replaced, otherwise the lamp replacement period will not be indicated 
correctly.1
