Replacing the Lamp
A lamp has a finite product life. Using the lamp for long periods of the time could cause the picture to
become darker or the color tone to become poor. Note that each lamp has a different lifetime, and some may
burst or burn out soon after you start using them.
1. Turn the projector off, and unplug the power cord. Allow the projector to cool for at least 45 minutes.
2. Prepare a new lamp.
3. After making sure that the projector has adequately cooled, slowly turn
the projector over so that the bottom is facing up.
4. Loosen the lamp cover screw (marked by the arrow), then slide and lift
the lamp cover.
5. Loosen the 2 lamp screws (marked by the arrow), and slowly lift the
lamp by the handles.

and the release of gas containing mercury.

the previous step to lock it in place.
7. Slide the lamp cover into place, and retighten the lamp cover screw
loosened in step 4.
