When Having Some Trouble
If you are having a problem with the projector, first check the projectors 
indicators.
The projector is provided with the following two indicators. These indicators 
alert you to problems with projector operation.
The following tables show what the indicators mean and how to remedy 
problems that they indicate.

High internal 
temperature
(overheating)The lamp will turn off automatically and 
projection will stop. Wait for about 5 minutes 
without operating the projector. After about 5 
minutes have elapsed, unplug the power cable 
and then check the following two points.
 Check that the air inlet and air outlet are 
clear, and that the projector is not positioned 
against a wall.
 If the air filter is dirty, it should be cleaned.
When the power cable is plugged back in, the 
projector will return to its previous state, so 
press the [Power] button on either the 
projectors control panel or the remote control 
to turn it back on. If the projector continues to 
overheat even after the above points have been 
checked, or if the indicators show a problem 
when the power is turned back on, stop using 
the projector, disconnect the power cable from 
the electrical outlet, and contact your dealer or 
the nearest address provided at International 
Warranty Conditions in Safety Instructions/
World-Wide Warranty Terms.p.16
p.73
Problem with 
lampDisconnect the power cable from the electrical 
outlet and then remove the lamp and check if it 
is broken. If the lamp is not broken, reinstall it. 
Then reconnect the power cable and press the 
[Power] button on either the projectors control 
panel or the remote control to turn the power 
back on.
If the indicators still show a problem, stop 
using the projector, disconnect the power cable 
from the electrical outlet, and contact your 
dealer or the nearest address provided at

Poor image quality (out of focus or distor ted)
Check the mode which corresponds to the frequency 
of the image signals being output from the computer.
Refer to the documentation provided with your computer 
for details on changing the resolution and frequency of the 
image signals being output from the computer. (p.86)
Are the cables connected correctly?
(p.17–23)
Does the input signal match the connected source?
Use the [Source] button on the projectors control panel (or 
the [Computer] or [S-Video/Video] button on the remote 
control) to select the correct signal source. (p.30)
Is the power for the computer or video source turned 
on? 
(p.29)
If a laptop computer or a computer with a LCD screen 
has been connected to the projector, it is necessary to 
output the image signals to the projector rather than 
to the screen.
Normally image signals are output to only the computers 
LCD screen, so you need to change the output to an 
external destination. For some computer models, when the 
image signals are output externally, they no longer appear 
on the LCD screen. For details, refer to the section of the 
documentation provided with your computer under a 
heading such as External output, Connecting an external 
monitor or similar. (p.30)
Has the focus been adjusted correctly? 
(p.37)
Is the lens cover still attached?
Has the front adjustable feet been adjusted so that the 
image angle is too big?
If the image angle is too big, the image will be out of focus 
vertically. (p.34)
Is the projector at the correct distance?
The recommended distance from the projector to the screen 
is within 0.9–11.3 m (2.9– 37.0 ft.). Set up the projector so 
that the projection distance is within this range. (p.16)

Has condensation formed on the lens?
If the projector is suddenly taken from a cold environment 
to a warm environment, 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 off the power and wait for the condensation to 
disappear.
