1. Turn the power off and disconnect the projector
from the wall socket. Turn off all connected
equipment and disconnect all other cables. See
"Turning the power off" on page 34 for details.
2. Slightly lift the projector up. Loosen the screws on
the lamp cover (located on the left side).
3. Remove the lamp cover.
4. Loosen the screws that hold the lamp to the
projector. If the screws are not loosened
completely, they could injure your fingers. It is
strongly recommended that you use a magnetic-
head screwdriver to retain the screw should it come
loose.
5. Slowly pull the lamp out of the projector.
Pulling it too quickly may cause the lamp to
break and scatter broken glass in the projector. To
reduce the risk of injuries to fingers and damage to
internal components, use caution when removing
lamp glass that has shattered.
Do not place the lamp in locations where water
might splash on it, children can reach it, near or
above heat sources, or near flammable materials.
Do not insert your hand into the projector when
the lamp is removed. If you touch the optical
components inside, it could cause blurred images.
6. Insert the replacement lamp. Make sure it is
pushed fully and firmly in place.
7. Tighten the screws securing the lamp box.
Please be careful to not over-tighten the
screws.
Loose screws may cause a bad connection,
which could result in malfunction.
8. Re-install the lamp cover.
9. Tighten the screws on the lamp cover.
10. Reapply power and turn the projector back on.
