Replacing the Lamp
•
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.
NOTE
All projector lamps will wear out eventually. If used for long periods of time, the image could become
darkened, and the color contrast could be impacted as well. We recommend that you replace your lamps
early. If the LAMP indicator turns red, or a message prompts you to replace the lamp when you power up
the projector, the lamp needs to be replaced. (See "Related Messages" and "Regarding the
Indicator
Lamps" for details.)

Turn off the projector, and unplug the power
cord. Allow the lamp bulb to cool for at least
45 minutes, and prepare a new lamp
