Troubleshooting (continued)
Images are not displayed correctly. (continued)
Problem
Solution
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.
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 51.)
• Some images and texts appear obscured during the keystone adjustment. In such
cases, use the projector without applying the keystone adjustment. (See page 11.)
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 32.)
Others
Problem
Solution
The exhaust vents
emit warm air.
• This air comes out after cooling the inside of the projector. You may feel hot, but this
is 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.
J
Turn off the main power, wait about 10 minutes, and turn on the main power again.
“TEMPERATURE!!” is
displayed.
• This indication appears when the ambient temperature rises high. When the ambient
temperature stays high, the lamp goes out.
J
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.
J
Remove 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 6.)
• Check that the remote control sensor isn’t exposed to direct sunlight or fl uorescent
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 buttons on the
projector (except for
the POWER button)
don’t function.
• PASSWORD FUNCTION in the FEATURE menu has been set to MENU ACCESS to
enable the password lock.
J
Cancel the password lock or contact the person in charge of management of the
projector. (See page 38.)
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.
