Solution
• Check that the batteries are loaded in the remote control or the batteries are not
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.
• When Standby Mode of the Efficient Mode menu in the Installation menu is set
to Speaker Out or Monitor Out, 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.
• Because the color wheel spins at a high speed, metallic sounds may be heard in rare
occasions. Such symptom is not a malfunction.
• Is the 3D mode of the projector set properly for the image?
Set 3D in the Picture menu of the projector properly for the image (Auto , Side by
Side , Top and Bottom , or Frame Sequential ).
• View 3D images from the front of the screen. At an angle to the screen, you may not
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.
• Are you viewing images from a very close distance?
Viewing images from a very close distance may not obtain the 3D effect. View
images from a proper distance.
• The 3D glasses may become out of sync due to fluorescent light. Turn off the
fluorescent light.
• Are the 3D glasses turned off?
Turn on the 3D glasses.
• The signals listed in the table on page 71 can be displayed in 3D format. You cannot
view other signals in 3D format even when you set 3D in the Picture menu to Auto ,
Side by Side , Top and Bottom , or Frame Sequential .
• You may not obtain the 3D effect depending on the capabilities of your computer
(including the graphic board, memory, and CPU).
• You cannot view 3D images when the LAN Display, USB Display, or PC Less
Presentation input source is selected.
• Some 3D glasses may not work with this projector. Ask the dealer for details.
• Depending on the 3D image status, you may feel something wrong with the 3D
images.
Switch the 3D Sync. Invert setting of the projector to check whether or not such
feeling is eliminated.
• The 3D glasses may become out of sync due to fluorescent light. Turn off the
fluorescent light.
• View 3D images from the front of the screen. At an angle to the screen, you may not
be able to view proper 3D images.
• Are the batteries of the 3D glasses still working?
If the 3D glasses don't activate even when you turn on the power switch, replace
or charge the batteries of the 3D glasses. For details, see the user manual of the
3D glasses.
