Phenomenon
P o w e r c a n n o t b e
turned on.
Check/Countermeasure
Adjust the projector and the screen so that they may become perpendicular to each other. (See Page 11.)
Adjust BRIGHT and CONTRAST in the picture quality menu. (See Page 28.)
Replace the lamp to a new one. (See Page 32 and 33.)
Adjust the focus. (See Page 18 and 22.)
Check if the lens cap is not put on.
Clean the lens.
Adjust "FINE" and "DIVIDING RATIO" in the signal setting menu. (See Page 30.)
Adjust BRIGHT and CONTRAST in the picture quality menu. (See Page 28.)
Adjust the projector and the screen so that they may become perpendicular to each other.

This phenomenon is proper to DLP projector and is not a failure. (A very small number of
pixels may be constantly lighting on or off, but this is not a failure. Pixels of more than
99.99% are effective ones.)
This pattern is a color breaking noise that occurs in DLP system in principle. This is not a
failure.
This phenomenon occurs due to the interference with the screen surface, and is not a
failure. Try to replace the screen or defocus the lens a little.
Securely plug the cable connecting the external equipment to the bottom.
Keep the projector away from equipment generating interfering radiowaves.
Check if the cable connecting the external equipment is broken.
Check/Countermeasure
• This air comes out after cooling the inside of the projector. It may feel hot, but is not a
failure.
• Affected by noises, the microcomputer in the projector may be malfunctioning.
–>Turn off POWER once, and after 2 minutes turn it on again.
• If POWER can not be turned off, turn off the main power switch and leave the projector as
it is for more than 10 minutes. Then, turn on POWER again.
• On rare occasions, a metallic clank occurs because the color wheel is rotating at a high
speed. But, this is not a failure.
Check/Countermeasure
•
Securely fit the rear lamp cover. (See Page 32 and 33.)
•
Reset the lamp-used-hours. (See Page 33.)
