Problem (continued)

Image color is incorrect

Image is out of focus

The image is stretched

when displaying a 16:9

DVD

Image is reversed

Lamp is burned out or

makes a popping sound

LAMP light is solid amber

Possible Solution (continued)

• If the display receives the wrong signal

output from the graphics card, please set

the signal type to RGB in the OSD Image

Settings of the Advanced Settings tab.

• Use Test Pattern in the Projector

Settings of the Advanced Settings

menu. Ensure that the colors of the test

pattern are correct.

Adjust the focus ring on the projector

lens.

Ensure that the projection screen is

within the required distance from the

projector (3.94 ft [1.2 m] ~ 32.81 ft [10

m]).

The projector automatically detects the

input signal format. It will maintain the

aspect ratio of the projected image

according to the input signal format with

an Original setting.

If the image is still stretched, adjust the

aspect ratio in the Display Settings of the

Advanced Settings menu in the OSD.

Select Projector Settings of the

Advanced Settings from the OSD and

adjust the projector mode.

When the lamp reaches its end of life, it

may burn out and may make a loud

popping sound. If this occurs, the

projector does not turn back on. To

replace the lamp, see "Changing the

Lamp" on page 22.

If the LAMP light is solid amber, replace

the lamp.
