Solution
• When Standby Mode in the Installation menu is set to LAN, 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 3D in the Picture menu set to On?
 Set 3D to On.
• 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.
• Is the 3D format of the displayed image supported by the projector?
 The projector supports only 3D images of the page flipping format/field sequential
format (that displays the left eye images and the right eye images sequentially).
Use 3D images of these formats.
• The signals listed in the table on page 68 can be displayed in 3D format. You cannot
view other signals in 3D format even when you set 3D in the Picture menu to On.
• 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.
• 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.
