Lamp Replacement
Caution
To reduce the risk of electrical shock, always turn off the projector and disconnect
the power cord before changing the lamp.
1. Press the
POWER
button to turn the main power switch off and disconnect the
power cord from the outlet.
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.
3. Loosen the
3
screws indicated by the arrows below. (It is strongly recommended
to use a magnetic-headed screwdriver, if possible. Pull the handle to remove the
lamp housing. If the screws are not loosened completely, they could damage
your fingers. Do not insert your hand into the box after the lamp is removed. If
you touch the optical parts inside, it could cause color unevenness, etc.
4. Replace the lamp with the new one, insert it in the projector, and tighten the
screws. Firmly tighten the lamp screws. Loose screws may cause a bad
connection, which may result in a malfunction.
5. Re-install the lamp cover and tighten the screw. Do not turn on the power with
the lamp cover removed. Whenever the lamp has been replaced, reset the total
operation time of the lamp. Do not reset if the lamp was not replaced, as this
could cause breakage.
