Replacing The Projection Lamp - Sharp XG-NV4SU Operation Manual

Replacing the Projection Lamp

The lamp in this projector operates for approximately 2,000 cumulative hours, depending on the usage environment.
When the lamp has been used for 1,900 hours, the LAMP REPLACEMENT indicator will light red and "LAMP" will
flash in yellow on the screen. It is recommended that the lamp be replaced after 1,900 cumulative hours of use or
when you notice a significant deterioration of the picture and color quality. If the lamp has been used for 2,000 hours,
the projector power will automatically turn off and the projector will enter standby mode. (Refer to "Lamp/Maintenance
Indicators" on page 29.) The lamp usage time can be checked with the On-screen Display (see page 19).
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. Purchase a replacement lamp unit (lamp/cage module) of the current
type BQC-XGNV4SU/1 from your nearest Authorized Sharp Industrial LCD Products Dealer or Service Center. Then
carefully change the lamp by following the instructions below. If you wish, you may have the lamp replaced at your
nearest Authorized Sharp Industrial LCD Products Dealer or Service Center.
