BenQ PB7200/ PB7220/ PB7100 User’s Manual
Step 1. Turn off the projector. Disconnect the power cord from the outlet and the
projector.
Step 2. Loosen the screw and remove the lamp
cover. If the lamp is hot, avoid burns by
waiting 45 minutes until the lamp has
cooled.
Step 3. Loosen the 3 screws. (It is strongly
recommended that you use a
magnetic-head screwdriver.) Pull the
handle to remove the lamp housing. If
the screws are not loosened
completely, they could injure your
fingers. Do not insert your hand into
the box after the lamp is removed. If
you touch the optical components
inside, this could cause color
unevenness in projected images.
Step 4. Replace the lamp with a new one.
Insert it into the projector, and tighten
the screws firmly. Loose screws may
cause a bad connection, which may
result in malfunction.
Step 5. Re-install the lamp cover and tighten
the screw. Do not turn on the
power with the lamp cover
removed. Whenever the lamp is
replaced, reset the total lamp
operation time. Do not reset if the
lamp is not replaced as this could
cause damage.
