Problem Solution
No sound comes
from the speakers
connected to the AV
amplifier. (No sound
comes from the
home theater system
speakers.)
t The projector is not equipped with the speakers. The AV amplifier reads the
information that projector is not equipped with the speakers and then passes this
information along to the DVD player. Because of this, either the DVD player may be
temporarily stopping audio output, or the AV amplifier may be temporarily stopping
audio output from the DVD player.
Change the setting on the AV amplifier or the DVD player.
The exhaust vents
emit warm air.
t This air comes out after cooling the inside of the projector. You may feel hot, but this
is not a malfunction.
The menu can’t be
used.
t The microcomputers inside the projector may be wrongly operating because of noise.
Press the POWER button to turn off the lamp and wait about 2 minutes. Then
unplug the power cord from the outlet, wait at least 10 minutes, and plug the
power cord back into the outlet. When the POWER button doesn't function, unplug
the power cord from the outlet, wait at least 10 minutes, and then plug the power
cord back into the outlet.
“TEMPERATURE!!” is
displayed.
t This indication appears when the ambient temperature rises high. When the ambient
temperature stays high, the lamp goes out.
Eliminate any causes of the rise in the ambient temperature.
t 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.
The
mark appears.
t This mark appears when ineffective operation is carried out. This isn’t a product
malfunction.
Troubleshooting (continued)
Images are not displayed correctly. (continued)
Problem Solution
Tint in projected
images is incorrect.
t Check that COMPUTER INPUT in the SIGNAL menu is correctly set. (See page 34.)
t Check that the cable connected to the external device isn’t broken.
Different color tint. t 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.
t 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.
Color unevenness
appears in images.
t Since the projector utilizes a high-definition DLP™ chip, color variations (at the center
of the screen and along the rims of the active area) that are caused by diffraction of
light may occur. This is not a malfunction.
Only the motion areas
in the images supplied
from the computer
aren’t displayed.
t This is caused by the computer being used. Contact the manufacturer of your
computer.
Projected images are
obscured.
t 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 59.)
Image remains
freezing.
t When image from VCR is projected, it may remain freezing during speed search. This
is not a malfunction.
Noise appears around
the image.
t 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 34.)
Projected images are
flickering.
t 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.
t When selecting the input signal and Auto Position, the projected image may be
flickering temporarily. This is not a product malfunction.
