No image appears on the screen. (continued) 
Images are not displayed correctly. 
ProblemSolution
Power turns off.   This problem may occur when the intake vent and/or exhaust vents are blocked. (In
such a case, the STATUS indicator brinks orange.)
JRemove the objects blocking the intake vent and/or exhaust vents and then 
carry out the following procedure.
1. Wait for the intake fan and/or exhaust fan to stop. (Wait until the STATUS 
indicator goes 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 steady red, it is indicating that the lamp should be
replaced. Replace the lamp in this case.
 Check that AUTO POWER OFF in the INSTALLATION menu has been set to OFF.
 If the lamp has deteriorated, it may go out after a while it illuminates.
The screen for entering 
the password appears. PASSWORD FUNCTION in the FEATURE menu has been set to DISPLAY INPUT 
to enable the password lock.
JEnter the password or contact the person in charge of management of the 
projector. (See page 62.)
“NO SIGNAL” is 
displayed. Turn on the power of the connected device, or check whether there is something
wrong with the connected device.
 Check whether the external device output signals. (Check this especially when the
external device is a laptop 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.
ProblemSolution
Projected images are 
shaking.
Projected images are 
displaced.  Check that the cable connected to the external device isn’t intermittent.
 Connect the cable’s plug with the external device’s connector firmly.
 Project an image containing a lot of characters without black areas and press the
AUTO POSITION button.
 Some computers output out-of-spec signals on rare occasion. In such a case,
change the setting of the SIGNAL DETECT in the FEATURE menu and press the
AUTO POSITION button. If the position (and size) of the projected images is still
incorrect, make adjustment using the SIGNAL menu. (For details, see flowchart on
page 38.)
Projected images are 
distorted.  Adjust the projector and the screen so that they are perpendicular to each other.
(See page 17.)
 Use the flat screen.
Projected images are 
dark.  Adjust BRIGHTNESS and CONTRAST in the IMAGE menu. (See page 26.)
 3D images displayed on the projector appear darker. It is normal and does not
mean the projector is malfunctioning.
 When viewing 2D images, set 3D FORMAT to AUTO   (for HDMI input only) or set
3D in the IMAGE menu to OFF. (When AUTO is selected, only 3D images become
darker.)
 Replace the lamp. (See page 67.) 
						

							EN-72
Troubleshooting (continued)
Images are not displayed correctly. (continued) 
ProblemSolution
Projected images are 
blurred.  Adjust the focus. (See page 19.)
 Clean the lens.
 Press the W or X button on the remote control to eliminate flicker.
 Adjust TRACKING and FINE SYNC. in the SIGNAL menu. (See page 30.)
 Set OVER SCAN in the SIGNAL menu to 100%. (See page 30.)
 Set the keystone adjustment to 0 using the KEYSTONE button. (See page 17.)
 Set the projected image size to maximum (0) in DIGITAL ZOOM function.(See page
12.)
 Adjust BRIGHTNESS and CONTRAST in the IMAGE menu. (See page 26.)
 Adjust the projector and the screen so that they are perpendicular to each other.
(See page 17.)
Afterimages persist on 
the screen. This phenomenon is improved by keeping projecting an evenly bright image. (Such
“image burn-in” phenomenon where afterimages persist on the screen may occur if
a stationary image is kept displayed on the screen for a long time.)
White dots are seen on 
projected images. Black 
dots are seen on 
projected images.  This phenomenon is normal for a DLP™ projector and is not a malfunction. (A very
small number of pixels may visibly or invisibly be persistent all the time, but they are
not a sign of system malfunctions. Over 99.99% of the pixels are effective.)
Fine streaks are seen on 
projected images. This is due to interference with the screen surface and is not a malfunction. Replace
the screen or displace the focus a little.
 Vertical or horizontal streak noise may appear on the projected image, depending
on the type of the DVD player, game console or computer you use. In such a case,
you can reduce such streak noise by enabling the LPF.
Projected images 
become wavy.  Connect the plugs of the cables to external devices securely.
 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.
Hue is not appropriate.   Check that the cables connected to the external devices are not broken.
Tint in projected images 
is incorrect. If the setting of COMPUTER INPUT in the SIGNAL menu is inconsistent with the
RGB/Y
CBCR output setting of the external device even when the input source is
other than computer (for example, when the input source is HDMI1 or HDMI2), the
entire image appears reddish or greenish.
 Check that COMPUTER INPUT in the SIGNAL menu is correctly set. (See page 30.)
 Check that the cable connected to the external device isn’t broken.
Different color tint.  When comparing images projected by two projectors, tints in the displayed images
may be different because of variation between their optical components. This is not
a malfunction.
 When comparing the image projected by this projector with those displayed on the
television or PC monitor, tints in the displayed images may be different because of
difference in the range of color reproducibility. This is not a malfunction
.
Only the motion areas in 
the images supplied from 
the computer aren’t 
displayed. This is caused by the computer being used. Contact the manufacturer of your
computer.

Images are not displayed correctly. (continued) 
Others 
ProblemSolution
Projected images are 
obscured. 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 79.)
 Some images and texts appear obscured during the keystone adjustment. In such
cases, use the projector without applying the keystone adjustment. (See page 17.)
Noise appears around the 
image. In some images such as DVD, noise may appear around the recorded image. In this
case, decrease the setting value of OVER SCAN of the SIGNAL menu. (See page
30.)
Projected images are 
flickering. After the POWER button or ON button on the remote has been pressed, or the
LAMP MODE setting has changed, images may be flickering until the lamp lights
stably. This is an expected behavior.
 When selecting the input signal, AUTO POSITION, and Image, the projected image
may be flickering temporarily. This is not a product malfunction.
 During LAMP MODE LOW2 is switched, projector images are little bit flickering for a
moment with constant timing. This phenpmenon is to keep lamp condition well and
is not a malfunction.
Projector images are 
twitching. Projector may be vibrating. Set AUTO KEYSTONE to OFF or lower the VOLUME T
button of the Remote control.
ProblemSolution
The exhaust vents emit 
warm air. This air comes out after cooling the inside of the projector. You may feel hot, but this
vis not a malfunction. 
No audio is output.  Check that the volume isn’t set to low.
 When the external device is connected with an HDMI cable, set the audio output of
the device to PCM output.
The menu can’t be used.   The microcomputers inside the projector may be wrongly operating because of
noise. 
JPress 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.
“TEMPERATURE!!” is 
displayed. This indication appears when the ambient temperature rises high. When the
ambient temperature stays high, the lamp goes out.
JEliminate 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. 
JRemove the objects blocking the air inlet or outlet grille.
The  mark appears.  This mark appears when ineffective operation is carried out. This isn’t a product
malfunction.
The remote control 
doesn’t function easily or 
at all. Check that the batteries are loaded in the remote control or the batteries are not
weak. (See page 9.)
 Check that the remote control sensor isn’t exposed to direct sunlight or fluorescent
light. (See page 9.)
 Use the remote control within its operation range. (See page 9.)
 Use the remote control at least 10 cm away from the projector.
The fans sound during 
standby. When STANDBY MODE is set to STANDARD, the fans rotate at very low speed
during standby after plugging the power cord (with 5 second high speed rotation at
the beginning) and after turning off the lamp. This is to cool down the projector
operating various functions during standby and is not a malfunction. 
						

							EN-74
Troubleshooting (continued)
Others (continued) 
If the following problem occurs after the lamp is replaced, check the following first. 
ProblemSolution
Abnormal sound is heard.   Because the color wheel spins at a high speed, metallic sounds may be heard in
rare occasions. Such symptom is not a malfunction.
Fan sound increse 
suddenly during LAMP 
MODE LOW2. During LAMP MODE LOW2 is switched, fan speed increase for a short time once
per 30 minutes. This phenomenon is to keep lamp condition well and is not a
malfunction.
