•  If any objects are blocking the air inlet or outlet grille, remove them and carry out 
the following.
1.  Unplug the power cord from the wall outlet.
2.  Make sure that the projector has cooled off. 
3.  Plug the power cord into the wall outlet.
4.  Press the POWER button.
•  If any objects are blocking the air inlet or outlet grille, remove them.
•  Don't expose the air outlet grilles to hot air emitted from a heating appliance.
•  After the STATUS indicator stops blinking, press the POWER button.
•  If you unplug the power cord while the fan is rotating, the lamp may not turn on about one minute when 
you plug the power cord next time. 
•  The lamp can't turn on again for one minute after it goes out. 
•  Press the POWER button several times.
•  Replace the lamp. (The lamp is at the end of its life.)
•  Attach the lamp cover on the bottom.

the lamp again. 
• If the projector was turned off before the lamp cooled down completely, the fans may start 
rotating and the POWER button may not function when you plug the power cord into the wall 
outlet next time. Wait for the fans to stop and press the POWER button to turn on the lamp 
again. 
• Set SCART INPUT in the FEATURE menu to OFF. (See page 18.)• Check that the lamp cover are closed. • Check that the cable connected to the external device isn't broken. • When an extension cord is being used, replace it with the supplied cable and check whether 
images are projected correctly. If images are projected correctly, use an RGB signal amplifier 
along with the extension cord. 
• The air inlet or outlet grille may be blocked. (In such cases, the STATUS indicator blinks orange.)  Remove the objects blocking the air inlet or outlet grille and carry out the following. 
1.  Wait for the air inlet or outlet fan to stop (or wait for the STATUS indicator to go out.)
2.  Unplug the power cord from the wall outlet.
3.  Wait about 10 minutes.
4.  Plug the power cord into the wall outlet.
5.  Press the POWER button.
• When the STATUS indicator is blinking red, it is indicating that the lamp should be replaced. 
Replace the lamp in this case. 
• Turn on the power of the connected device, or check whether there is something wrong with 
the connected device.
• Check whether the external device outputs signals. (Check this especially when the external 
device is a notebook computer.) 
• Check that the cable connected to the external device isn't defective. • Check that the projector is connected to the external device using the correct terminals. • Check that the connected device is correctly selected as the input source. • When an extension cord is being used, replace it with the supplied cable and check whether 
images are projected correctly. If images are projected correctly, use an RGB signal amplifier 
along with the extension cord. 
• PASSWORD FUNCTION in the FEATURE menu has been set to DISPLAY INPUT to enable the 
password lock. 
 Enter the password or contact the person in charge of management of the projector. (See page

Troubleshooting (continued)
Images arent projected correctly.
Problem
Projected images are 
shaking.
Projected images are dis-
placed. 
Projected images are dis-
torted.
Projected images are dark. 
Projected images are 
blurred. 
White dots are seen on 
projected images.
Black dots are seen on 
projected images.
Rainbow blur appears in 
projected images. 
Fine streak pattern ap-
pears in projected images.
Projected images (and/or 
audio) appear wavy and 
distorted. 
Tint in projected images is 
incorrect.
Only the motion areas in 
the images supplied from 
the computer aren't dis-
played. 
Projected images are ob-
scured.
Cause and solution
• Check that the cable connected to the external device isn't intermittent. • Connect the cable's plug with the external device's connector firmly.• Press the AUTO POSITION button.• Some computers output out-of-spec signals on rare occasion. Adjust the SIGNAL menu. (See page 
20.)
• Adjust the projector and the screen so that they are perpendicular to each other. (See page 13.)
• Adjust BRIGHTNESS in the IMAGE menu. (See page 19.)• Replace the lamp. (See page 26.)
• Adjust the focus. (See page 14.)• Clean the lens.• Press the  or  button on the remote control to eliminate flicker. • Adjust BRIGHTNESS and CONTRAST in the IMAGE menu. (See page 19.)• Adjust the projector and the screen so that they are perpendicular to each other. (See page 13.)
• This symptom is normal for a DLP projector and is not a malfunction. (A very small number of pixels 
may stay lit or out, but such sympton is not a malfunction. Pixels of 99.99% or more are effective.)
• Such blur appears based the principle of the DLP system. It isn't a failure.
• It occurs because of interference with the screen and isn't a product malfunction. Change the screen 
or readjust the focus of the projector.
• Connect the cable's plug with the external device's connector firmly.• Keep the projector away from equipment generating interfering radio waves.• When the keystone adjustment is carried out, the image may not be displayed correctly because of 
the type of input signal. This isn't a product malfunction. In this case, readjust the keystone so that 
the amount of keystone correction is as small as possible.
• Check that COMPUTER INPUT in the SIGNAL menu is correctly set. (See page 18.)• Check that the cable connected to the external device isn't broken. 
• This is caused by the computer being used. Contact the manufacturer of your computer.
• Match the output resolution of your computer with the resolution of the projector.  For the method to 
change the output resolution of the computer, contact the manufacturer of your computer. (See page 
33.)
• Some images and texts appear obscured during the keystone adjustment. In such cases, use the 
projector without applying the keystone adjustment. (See page 13.)

Others
Cause and solution
• This air comes out as a result of cooling the inside of the projector. This isn't a product malfunc-
tion. 
• Check that the volume isn't set to low. 
• The microcomputers inside the projector may be wrongly operating because of noise. 
 Press the POWER button to turn off the lamp and unplug the power cord from the wall outlet. Wait 
about 10 minutes, plug the power cord in, and try again.
• This indication appears when the ambient temperature rises high. When the ambient tempera-
ture stays high, the lamp goes out.
 Eliminate any causes of the rise in the ambient temperature.
• This indication appears when the air inlet or outlet grille is blocked. When they are kept blocked, 
the lamp goes out. 
 Remove the objects blocking the air inlet or outlet grille. 
• This mark appears when ineffective operation is carried out. This isn't a product malfunction. 
• Check that the battery is loaded in the remote control or the battery isn't weak. (See page 8.)
• Check that the remote control sensor isn't exposed to direct sunlight or fluorescent light. (See 
page 8.)
• Use the remote control within its operation range. (See page 8.)
• Use the remote control at least 10 cm away from the projector. 
• PASSWORD FUNCTION in the FEATURE menu has been set to MENU ACCESS to enable the 
password lock. 
 Cancel the password lock or contact the person in charge of management of the projector. (See page 
25.)
• Because the color wheel spins at a high speed, metalic sounds may be heard in rare occations. 
Such sympton is not a malfunction.
When the problems below occur after the lamp is replaced, check the following. 
Problem
The power isn't turned 
on. 
The STATUS indicator 
blinks.
Problem
Hot air is emitted from the 
air outlet grilles. 
No audio is output. 
The menu can't be used. 
TEMPERATURE!! is dis-
played.
The 
 mark appears. 
The remote control doesn't 
function easily or at all.
The buttons on the control 
panel (except for the 
POWER button) don't 
function. 
Cause and solution
• Attach the lamp cover on the bottom correctly. 
• Reset the lamp operation time. (See page 26.)
• Reset the lamp operation time. (See page 26.)
Maintenance
Caution:
Be sure to turn off the lamp and unplug the power cord from the wall outlet before you perform any maintenance on 
the projector. 
Cleaning of the projector and the ventilation slots
Use a soft cloth to clean the projector and the ventilation grilles. When the grilles become dirty, wipe them with a soft 
cloth dampened with diluted mild detergent, and then wipe them with a dry cloth.
To protect the surface of the projector from fading or deteriorating:
•  Do not spray insecticide on or inside the projector.
•  Do not use benzine or thinner to clean it.
•  Do not let rubber or plastic materials contact with projector.
Cleaning of the lens
Use a standard lens-cleaning brush or a piece of lens tissue dampened with lens cleaning fl uid. The lens surface is 
fragile. Use only recommended, nonabrasive lens-cleaning materials. Do not touch the lens with your fi ngers.
Abnormal sound is heard.
