Lamp/Maintenance Indicators
Lamp
■ The Lamp has a finite operating life. The lamp for this projector has a usable life of 2000 cumulative hours. This
number may differ, however, depending on the ambient conditions.
1. When the lamp is nearing the end of its operating life, the picture and color quality will deteriorate. If the lamp is
used for more than 1900 hours, the LAMP REPLACEMENT indicator will light red and “LAMP” will flash in
yellow letters on the screen when you turn the projector on to alert you that it is time to replace the lamp. In this
situation, replace the lamp (See pages 32 and 33).
Note: The lamp usage time can be checked at the On-Screen display. (See page 27.)
Caution: Once you are alerted that the lamp requires replacement, be sure to replace the lamp.
2. When the number of hours the lamp is used reaches 2000, 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 2000 hours, “LAMP” will
flash on screen in red letters for five minutes and then the power will turn off.
3. If the new lamp does not light after replacement, take your projector to the nearest Authorized Sharp Industrial
LCD Products Dealer or Service Center for repair.
4. 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 bulb.
■ If a problem occurs, either the TEMPERATURE indicator or the LAMP REPLACE-
MENT indicator will light up red, and the power will shut off. After turning off the
power, follow the procedures given below.
