Troubleshooting (continued)

Images are not displayed correctly.

Problem		Solution	ENGLISH
	• 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.
Projected images are displaced.	• Press the AUTO POSITION button.
	• Some computers output out-of-spec signals on rare occasion. Adjust the SIGNAL menu. (See page 37.)
	• When the input signal is a WXGA video signal, confirm the setting selected 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 10.)
Projected images are dark.	• Adjust BRIGHTNESS and CONTRAST in the IMAGE menu. (See page 36.)
	• Replace the lamp. (See page 40.)
	• Adjust the focus. (See page 15.)
	•	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 37.)
	• Adjust BRIGHTNESS and CONTRAST in the IMAGE menu. (See page 36.)
	• Adjust the projector and the screen so that they are perpendicular to each other. (See page 10.)
	• This phenomenon is improved by keeping projecting an evenly bright image. (Such "image burn-in" phenom-

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

		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 35.)
	• 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.

	• Some images and texts appear obscured during the keystone adjustment. In such cases, use the projector
		without applying the keystone adjustment. (See page 14.)
	• After the Power button or On button on the remote has been pressed, or the Lamp mode setting has

	• When selecting the input signal, Auto Position, and Color Enhancer, the projected image may be flickering
		temporarily. This is not a product malfunction.
