Problem Solution
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.

Cancel the password lock or contact the person in charge of management of the
projector. (See page 61.)
The fans sound during
standby. • When STANDBY MODE in the INSTALLATION menu 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 light source. This is
to cool down the projector operating various functions during standby and is not a
malfunction.
Abnormal sound is
heard. • Because the motor spins at a high speed, metallic sounds may be heard in rare
occasions. Such symptom is not a malfunction.
Images are not 3D.
* Use commercially
available 3D glasses
supporting the DLP™
Link™ system. No 3D
glasses are supplied
with the projector.
• Is the 3D mode of the projector set properly for the image?

Set 3D FORMAT in the IMAGE-3D menu of the projector properly for the image
(SIDE BY SIDE , TOP AND BOTTOM or FRAME SEQUENTIAL ).

be able to view proper 3D images.
• Is there any obstacle between the 3D glasses and the screen? Or, is there any sticker
or label over the sensor of the 3D glasses?

The 3D glasses work by receiving signals of the images being viewed. Check that
there is no obstacle between the 3D glasses and the screen.
