Solution
• 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.
• You cannot select grayed-out items. (See page 29.)
• 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.
• This indication appears when the intake or exhaust vents are blocked. When they are
kept blocked, the lamp goes out.
 Remove the objects blocking the intake or exhaust vents.
• This mark appears when ineffective operation is carried out. This isn't a product
malfunction.
• 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 fluorescent
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.
• When you are viewing a 3D image, stop the signal being output from the 3D emitter
temporarily by pressing the 3D SYNC PAUSE button on the remote control. (See page
26.)
• 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 41.)
• The iris produces sound while operating. This is not a malfunction.
• For HC8000D, mechanical operation noise is heard after the power-on process or
when the setting of IRIS2 in the IRIS menu is changed, but this is not a malfunction.
• Mechanical operation noise is heard after the power-off process, but this 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.
• For HC8000D, is 3D GLASSES of 3D in the IMAGE menu set correctly? (See page 25.)
• Is the 3D emitter connected to the projector?
• Is there any block in the communication area between the 3D emitter and the 3D
glasses? Or, is there a sticker or other such item on the infra-red reception section on
the 3D glasses?
 The 3D glasses operate by receiving signals from the 3D emitter. Check that there
is not any block in the communication area between the 3D emitter and the 3D
glasses.
• Is the distance between the 3D emitter and 3D glasses too far, or too close?
 Adjust the location of the 3D emitter.
• Are the direction of the 3D emitter and that of the infra-red reception section on the
3D glasses misaligned?
 Adjust the direction and location of the 3D emitter.
• Is the 3D glasses turned off?
 Turn on the power of the 3D glasses.
