Lamp/Maintenance Indicators
Lamp
The lamp operating life differs, depending on the usage environment. It is recommended that the lamp be
replaced after 4,000 cumulative hours of use.
• When the lamp is nearing the end of its operating life, the picture and color quality will deteriorate. At this point, replace the
lamp. (See pages 31 and 32.)
Check
• The projector AC cord is not plugged into the AC wall outlet.
• The main power switch is not pressed.
• The input is wrong. (See pages 22 and 23.)
• Cables improperly connected to rear panel of the projector. (See pages 14, 15, 16 and 17.)
• Remote control batteries have run down. (See page 7.)
• The optional cable for the remote control is improperly inserted.
• The main power of the remote control is not turned on.
• The remote control’s MOUSE/ADJUSTMENT switch is set to MOUSE.
• Cables improperly connected to rear panel of the projector. (See pages 14, 15, 16 and 17.)
• The PICTURE and BRIGHT adjustments are set to minimum position. (See page 24.)
• On-Screen Display (“BLACK SCREEN”) is turned off and Black Screen function is turned on, creating a
black image. (See page 27.)
• The COLOR and TINT adjustments are not correct. (See page 24.)
• Adjust the focus. (See page 9.)
• The projection distance is too long or too short to allow for proper focus. (See page 10.)
• Cables improperly connected to rear panel of the projector. (See pages 14, 15, 16 and 17.)
• Volume is set to minimum. (See page 23.)
• If the picture is normal, the sound is due to cabinet shrinkage caused by temperature changes. This
will not affect operation or performance.
• Refer to “Lamp/Maintenance Indicators” on page 30.

before turning the power back on. (At least 5 minutes.)
• When the power is turned off and then turned on again, as during a brief rest, the LAMP REPLACEMENT indicator may be triggered, pre-
venting the power from going on. When this happens, take the power plug out of the AC outlet and put it back in again.
