Lamp Life

Projector lamps have a finite life. The projected images will become darker and hues will become weaker after a lamp has been used for a long period of time.

The LAMP indicator also becomes red when the lamp unit reaches a high temperature. Before replacing the lamp, switch the POWER OFF, wait approximately 20 minutes, then switch the POWER ON again. If the LAMP indicator still displays red, replace the lamp.

Replacing the Lamp

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.

1Turn off the projector, and unplug the power cord. Allow the lamp bulb to cool for at least 45 minutes, and prepare a new lamp

2After making sure that the projector has cooled adequately, slowly flip over the projector, so that the bottom is facing up

3Unscrew the 2 screws, and remove the lamp cover

4Unscrew the 1 screw, and slowly pull out the lamp by the handle

Be careful not to touch the inside of the lamp case.

5Insert the new lamp, and tighten the 1 screw firmly to lock it in place

Also steadily push the opposite side of the screwed side of the lamp into the unit.

6Replace the lamp cover, and tighten the 2 screws firmly to lock it in place

7Slowly turn the projector so that the top is facing up

8Turn on the projector power, and using the menu, reset the lamp timer

To reset the lamp timer, from the OPTION menu, select LAMP TIME.
