Lamp Replacement
How to check Lamp used time
The LAMP REPLACE indicator will light yellow when
the total lamp used time (Corresponding value) reaches
2000 hours. This is to indicate that lamp replacement is
required.
The total lamp used time is calculated by using the be-
low expression,
Total lamp used time = Teco + Tnormal x 2
Teco: used time in the Eco mode
Tnormal : used time in the Normal mode
You can check the lamp used time following to the below
procedure.
1 Press and hold the POWER ON-OFF button on the
projector for more than 20 seconds.
2 The projector used time and lamp used time will be
displayed on the screen briefly as follows.
Lamp replacement
WARNING:
- For continued safety, replace with a lamp assembly of the same type.
- Allow the projector to cool for at least 45 minutes before you open the
lamp cover. The inside of the projector can become very hot.
- Do not drop the lamp module or touch the glass bulb! The glass can
shatter and cause injury.
Procedure
1 Turn off the projector and disconnect the AC cord.
2 Remove 1 screw with a screwdriver and remove the lamp cover.
3 Loosen 2 screws and pull out the lamp assembly by grasping the
handle.
4 Replace the lamp with a new one and tighten the 2 screws back into
position. Make sure that the lamp is set properly. Replace the lamp
cover and tighten the screw.
5 Connect the AC cord to the projector and turn on.
6 Reset the lamp replacement counter, see below explanation.
Note
- The projector cannot be turned-on with lamp cover removed, because
when the lamp cover is removed, the lamp cover switch is also re-
leased to switch off the lamp circuit.
How to reset Lamp Replace Counter
1 Turn the projector on, press the MENU button and the
On-Screen Menu will appear. Press the Point Left/
Right button to move the red frame pointer to the Set-
ting Menu icon.

Recommendation
Should the air filter become clogged with dust particles,
it will reduce the cooling fan’s effectiveness and may re-
sult in internal heat build up and short lamp life. We rec-
ommend cleaning the air filter after the projection lamp
is replaced.
Refer to “Air Filter Cleaning”.
