Troubleshooting
■ Interference or distortion appear in images
■ Image is truncated (large) or small
Has condensation formed on the
lens?
If the projector is suddenly taken from a cold environment to a
warm environment or if sudden ambient temperature changes
occur, condensation may form on the surface of the lens, and this
may cause the images to appear fuzzy. Set the projector up in the
room approximately one hour before it is to be used. If
condensation forms on the lens, turn the power off and wait for the
condensation to disappear.
Are the image signal format
settings correct?
If a composite video
or S-Video
is being input
If projection does not occur when the "Video Signal" menu
command is set to "Auto", select the signal format that matches the
signal source.
"Settings" - "Input Signal" - "Video Signal" p.33
If the signal source is connected to the [Component] port
If projection does not occur when the "Component" in the "Input
Signal" menu command is set to "Auto", set the signal format that
matches the signal that is being projected from the connected
equipment. "Settings" - "Input Signal" - "Component" p.33
You can also press
on the remote control to select the
format. p.15
Are the cables connected
correctly?
Check that all of the cables required for projection are securely
connected.
p.12
Is an extension cable being
used?
If an extension cable is used, interference may increase. Try
connecting a signal amplifier.
Have the "Sync.
" and
"Tracking
" settings been
adjusted correctly?
The projector has an automatic adjustment function that causes the
optimum images to be projected. However, for some types of
signal, the correct adjustments may not be obtained even after
automatic adjustment is carried out. In such cases, use the
"Tracking" and "Sync." menu commands to make the adjustments.
"Image" - "Tracking", "Sync." p.29
Has the correct resolution been
selected?
Set the computer so that the signals that are output are compatible
with this projector.
"List of Supported Monitor Displays" p.47
Computer documentation
Has the correct aspect
been
selected?
Press
to select the aspect that corresponds to the input
signal.
p.18
If images with subtitles are being projected using "Zoom", use the
"Zoom Caption" menu command to adjust the images.
p.29
Has the "Position" setting been
adjusted correctly?
Use the "Position" the menu command to make the adjustment.
"Image" - "Position" p.30
Has the computer been set for
dual display?
If dual display has been activated in the Display Properties of the
computer's Control Panel, the projector will only project about half
of the image on the computer screen. To display the whole of the
image on the computer screen, turn off the dual display setting.

it. If this does not solve the problem, there may be a problem with
the power cable. Then contact your local dealer or the nearest
address provided in the World-Wide Warranty Terms.
Inquiries
Is the remote control light-
emitting area facing towards the
remote control light-receiving
area when it is operated?
Face the remote control towards the remote control light-receiving
area.
The operating angle for the remote control is approximately ±30°
horizontally and approximately ±30° vertically.
p.13
Is the remote control too far
from the projector?
The operating range for the remote control is approximately 10m.
p.13
Is direct sunlight or strong light
from fluorescent lamps shining
onto the remote control light-
receiving area?
Set the projector up in a location where strong light will not shine
onto the remote control light-receiving area.
Are the batteries dead, or have
the batteries been inserted
correctly?
Insert new batteries, while making sure that they face correctly.

Maintenance
This 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.
Cleaning the air filter
If the air filter becomes blocked with dust and the message
"The projector is overheating. Make sure nothing is blocking
the air vent, and clean or replace the air filter" is displayed,
clean the air filter.
Turn the projector upside-down and use a vacuum cleaner to
clean the air filter
Cleaning the projector case
Clean the projector case 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
projector case. Then wipe the case again with a soft, dry cloth.
Cleaning the lens
To clean the lens it is preferable to use an air blower
purchased for the purpose. But alternatively you can wipe it
gently clean with a spectacle-cleaning cloth.
Be sure to read the separate Safety Instructions/World-Wide Warranty Terms booklet for details
on safe handling of the projector during cleaning.
If the air filter becomes clogged with dust, it can result
in overheating which may cause operating problems or
reduce the operating life of the optical parts. It is
recommended that you clean the air filter about once
every three month. If using the projector in a dusty
location, the air filter should be cleaned more often.
Do not use volatile substances such as wax, alcohol or
thinner to clean the projector case. These can cause
the case to warp and make the coating finish peel off.
Do not rub the lens with harsh materials or subject the
lens to shocks, as it can easily become damaged.

Consumable replacement periods
Air filter replacement period
• If the air filter has been broken or the "Replace" message is displayed even though the
air filter has been cleaned.
Replace with an optional air filter.
Replacing the air filter p.44
Lamp replacement period
• The message "Replace the lamp." appears on the screen when projection starts.
• The projected images get darker or start to deteriorate.
•The replacement warning message is set to appear after a minimum of about 1600
hours of lamp use in order to maintain the initial brightness and quality of the
projected images. The time taken for the message to appear will vary depending on
usage conditions such as Color Mode settings.
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.
A message will be displayed.
