DT00491 lamp replacement and time  

Lamp Life

Projector lamps have a finite life. The image will become darker, and hues will become weaker,

after a DT00491 lamp has been used for a long period of time.

The LAMP indicator is also red when the lamp unit reaches high temperature. Before

replacing the lamp, switch power OFF, wait approximately 20 minutes, and switch power ON again.

If the LAMP indicator is still red, replace the lamp.

Replacing the Lamp

1. Switch the projector OFF, remove the power cord from the

power outlet, and wait at least 45 minutes for the unit to cool.

2. Prepare a new lamp.

3. Check that the projector has cooled sufficiently, and gently

turn it upside down.

4. Loosen the screw as shown in the diagram, and remove the

lamp cover.

5. Loosen the two screws, and gently remove the lamp while

holding the grips. Touching the inside of the lamp case may

result in uneven coloring.

6. Install the new lamp and tighten the two screws firmly. Also

steadily push the opposite side of the screwed lamp into the

unit.

7. Replace the DT00491  lamp cover in position and tighten the screw

firmly.

8. Gently turn the projector right-side up.

Resetting the Lamp Timer

Reset the lamp timer after replacing the lamp. When the lamp has been replaced after the LAMP

indicator is red, or the CHANGE THE LAMP message is displayed, complete the following
