Lamp/Maintenance Indicators
Lamp
■
The Lamp has a finite operating life of 1,500 hours. The lamp life may differ, however, depending on the usage environment.
• When the lamp is nearing the end of its operating life, the picture and color quality will deteriorate. When the projector is
turned on after the lamp has been in use for more than 1,400 hours, the LAMP REPLACEMENT indicator will light red and
“LAMP” will flash in yellow on the screen to alert you that it is time to replace the lamp. At this point, take your projector to the
nearest Authorized Sharp Industrial LCD Products Dealer or Service Center to have the lamp replaced.
Note:
The lamp usage time can be checked with the On-Screen display. (See page 28.)
Caution: Once you are alerted that the lamp requires replacement, take your projector to the nearest Authorized Sharp
Industrial LCD Products Dealer or Service Center to have the lamp replaced.
• When the number of hours the lamp has been used reaches 1,500, the power automatically turns off and the projector enters
the standby condition. If you turn on the power after the lamp has been used for 1,500 hours, “LAMP” will flash on screen in
red letters for five minutes and then the power will turn off.
• Intense light hazard. Do not attempt to look into the aperture and lens while the projector is operating.
Maintenance Indicators
■
The warning lights on the projector indicate problems inside the projector.
■
There are two warning lights–a TEMPERATURE indicator which warns that
the projector is too hot, and a LAMP REPLACEMENT indicator which lets
you know when to change the lamp.
■
If a problem occurs, either the TEMPERATURE indicator or the LAMP
REPLACEMENT indicator will light up red, and the power will shut off. After
turning off the power, follow the procedures given below.
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 24 and 25.)
• Cables improperly connected to side panel of the projector. (See pages 15, 16, 17, 18 and 19.)
• 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.
• The lamp has reached the end of its operating life. (See page 32.)
• Cables improperly connected to side panel of the projector. (See pages 15, 16, 17, 18 and 19.)
• The BRIGHTNESS and PICTURE adjustments are set to minimum position. (See page 26.)
• On-Screen Display (“BLACK SCREEN”) is turned off and Black Screen function is turned on, creating
a black image. (See page 29.)
• The COLOR and TINT adjustments are not correct. (See page 26.)
• 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 side panel of the projector. (See pages 15, 16, 17, 18 and 19.)
• Volume is set to minimum. (See page 25.)
• 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 32.

Notes:
•
If the TEMPERATURE indicator comes on, follow the above possible solutions and then wait until the projector has cooled down completely
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, preventing the
power from going on. When this happens, take the power plug out of the AC outlet and put it back in again.
