Troubleshooting
Before calling your dealer or service center for assistance, check the items below once again.
1. Make sure you have properly connected the projector to peripheral equipment as described \
on pages 24–26.
2.  Check the cable connection. Make sure that all computers, video equipment, and power cords are properly 
connected.
3.  Make sure that all power is switched on.
4.  If the projector still does not produce an image, restart your computer.
5.  If an image still does not appear, disconnect the projector from your computer and check your computer 
monitor’s display. A problem may be noticed with your graphics controller rather than with the projector. 
(When you reconnect the projector, be sure to turn the computer and monitor off before you turn on the 
projector. Turn on equipment in the order of the projector and computer.)
6.  If a problem still persists, check the following solutions.
Appendix

– Plug the power cord of the projector into the AC outlet.
–  
Wait  until  the  POWER  indicator  stops  blinking  to  turn  on  the  projector  again.  (See 
page 28)
–   Check the WARNING TEMP. indicator. If the WARNING TEMP. indicator is blinking, the 
projector cannot be turned on. (See page 70.)
–  Unlock the Key lock function for the projector.  (See page 59)
–   See if the filter cartridge is inserted.  (See page 64)
– Check the projection lamp.  (See page 66.)

No image.
– Check the connection between your computer or video equipment and the projector.
–    See  if  the  input  signal  is  correctly  output  from  your  computer.  Some  laptop 
computers  may  need  to  be  changed  the  setting  for  monitor  output  when  connected 
to the projector. See your computer’s instruction manual for the setting.
– It takes about 30 seconds to display an image after turning on the projector.
– See if the selected system is corresponding with your computer or video equipment.
–    Select correct input source once again through menu operation  (See pages 37-39).

location may result in moisture condensation on Projection Lens.  In such cases, 
leave the projector OFF and wait until condensation evaporates.
–    Projecting  from  excessive  slant  angle  to  the  screen  may  cause  keystone  distortion 
and partial imperfect focus.
– Make sure the projection screen is at least 4.6’ (1.4 m) away from the projector.
The image is not bright 
enough.
– Check if “Contrast” or “Brightness” are adjusted properly. (See page 51) 
– Check if “Image level” is selected properly. (See pages 44, 48)
