Replacing the Lamp
It is recommended that the lamp be replaced after approximately 1,900 cumulative hours of use or when you
notice a significant deterioration of the picture and colour quality. Carefully change the lamp by following the steps
on the next page.
If the new lamp does not light after replacement, take your projector to the nearest Sharp Authorised Projector
Dealer or Service Centre for repair. Purchase a replacement lamp unit (lamp/cage module) of the current type
BQC-XVZ9000/1 from your nearest Sharp Authorised Projector Dealer or Service Centre. Then carefully change
the lamp by following the instructions on the next page. If you wish, you may have the lamp replaced at your
nearest Sharp Authorised Projector Dealer or Service Centre.
CAUTION
• There is potential glass particles hazard if the lamp ruptures. In case of lamp rupture, contact your
nearest Sharp Authorised Projector Dealer or Service Centre for replacement.
• Do not remove the lamp cage directly after operation of the projector. The lamp may be extremely
hot. Wait at least one hour after the power cord is disconnected to allow the surface of the lamp cage
to fully cool down before removing the lamp cage.
