Troubleshooting (continued)

Images are not displayed correctly.

Problem

 

Solution

 

 

 

• Check that the cable connected to the external device isn’t intermittent.

Projected images are shaking.

• Connect the cable’s plug with the external device’s connector firmly.

•

Press the AUTO POSITION button.

Projected images are displaced.

•

Some computers output out-of-spec signals on rare occasion. Adjust the SIGNAL menu. (See page 24.)

 

• When the input signal is a WXGA video signal, confirm the setting selected in WXGA in the FEATURE menu.

 

• When the input signal is other than a WXGA video signal, select "OFF" in WXGA in the FEATURE menu.

 

 

 

Projected images are distorted.

•

Adjust the projector and the screen so that they are perpendicular to each other. (See page 9.)

 

 

Projected images are dark.

• Adjust BRIGHTNESS and CONTRAST in the QUICK MENU or the IMAGE menu. (See page 23.)

• Replace the lamp. (See page 27.)

 

 

 

 

• Adjust the focus. (See page 13.)

 

•

Clean the lens.

Projected images are blurred.

• Press the W or X button on the remote control to eliminate flicker.

• Adjust TRACKING and FINE SYNC. in the SIGNAL menu. (See page 24.)

 

 

• Adjust BRIGHTNESS and CONTRAST in the QUICK MENU or the IMAGE menu. (See page 23.)

 

• Adjust the projector and the screen so that they are perpendicular to each other. (See page 9.)

 

 

 

• This phenomenon is improved by keeping projecting an evenly bright image. (Such "image burn-in" phenom-

Afterimages persist on the screen.

 

enon where afterimages persist on the screen may occur if a stationary image is kept displayed on the screen

 

 

for a long time.)

 

 

White dots are seen on projected images. Black dots

• This phenomenon is normal for a DLP projector and is not a malfunction. (A very small number of pixels may

 

visibly or invisibly be persistent all the time, but they are not a sign of system malfunctions. Over 99.99% of

are seen on projected images.

 

 

the pixels are effective.)

 

 

 

 

 

• This is due to interference with the screen surface and is not a malfunction. Replace the screen or displace

 

 

the focus a little.

Fine streaks are seen on projected images.

•

Vertical or horizontal streak noise may appear on the projected image, depending on the type of the DVD

 

 

player, game console or computer you use. In such a case, you can reduce such streak noise by enabling the

 

 

LPF.

 

 

 

• Connect the plugs of the cables to external devices securely.

 

• Keep the projector away from equipment generating interfering radio waves.

Projected images become wavy.

•

When the keystone adjustment is carried out, the image may not be displayed correctly because of the type

 

 

of input signal. This isn’t a product malfunction. In this case, readjust the keystone so that the amount of key-

 

 

stone correction is as small as possible.

 

 

 

Hue is not appropriate.

•

Check that the cables connected to the external devices are not broken.

 

 

Tint in projected images is incorrect.

• Check that COMPUTER INPUT in the SIGNAL menu is correctly set. (See page 22.)

• Check that the cable connected to the external device isn’t broken.

 

 

 

 

• When comparing images projected by two projectors, tints in the displayed images may be different because

 

 

of variation between their optical components. This is not a malfunction.

Different color tint.

•

When comparing the image projected by this projector with those displayed on the television or PC monitor,

 

 

tints in the displayed images may be different because of difference in the range of color reproducibility. This

 

 

is not a malfunction.

 

 

 

Only the motion areas in the images supplied from

• Match the output resolution of your computer with the resolution of the projector. For the method to change

Projected images are obscured.

 

the output resolution of the computer, contact the manufacturer of your computer. (See page 35.)

• Some images and texts appear obscured during the keystone adjustment. In such cases, use the projector

 

 

 

without applying the keystone adjustment. (See page 12.)

 

 

 

• After the Power button or On button on the remote has been pressed, or the Lamp mode setting has

changed, images may be flickering until the lamp lights stably. This is an expected behavior.

• When selecting the input signal, Auto Position, and Color Enhancer, the projected image may be flickering

 

 

 

temporarily. This is not a product malfunction.
