Maintenance
28 Step 1. Turn the projector off. Discon-
nect 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 min-
utes until the lamp has cooled. 
Step 3. Loosen the 3 screws. (It is  strongly recommended that you 
use a magnetic-head screw-
driver.) Pull the handle to 
remove the lamp housing. If the 
screws are not loosened com-
pletely, you could injure your 
fingers. Do not insert your hand 
into the projector 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 the 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  
the power on 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.
