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 | |||

|
|
| |
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 Picture menu. (See page 16.) | ||
• Replace the lamp. (See page 20.) | |||
| |||
|
| ||
| • Adjust the focus. (See page 13.) | ||
| • | Clean the lens. | |
Projected images are blurred. | • | Adjust Tracking and Fine sync. in the Computer Image menu. (See page 17.) | |
| • Adjust Brightness and Contrast in the Picture menu. (See page 16.) | ||
| • 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 | ||
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 | ||
Fine streaks are seen on projected images. |
| the focus a little. | |
• Vertical or horizontal streak noise may appear on the projected image, it may depend on the type of the DVD | |||
| |||
|
| player, game console or computer you use. | |
|
| ||
| • 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 Signal Type in the Setting menu is correctly set. (See page 18.) | ||
• 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. | |

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

| the output resolution of the computer, contact the manufacturer of your computer. (See page 27.) | |
• 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 ON button on the remote has been pressed, or the Lamp mode setting has changed, images may | |
Projected images are flickering |
| be flickering until the lamp lights stably. This is an expected behavior. | |
• | When selecting the input signal, AUTO POSITION and Image in Menu, the projected image may be flicker- | ||
| |||
|
| ing temporarily. This is not a product malfunction. | |
