Images are not displayed correctly.
“NO SIGNAL” is displayed. • Turn on the power of the connected device, or check whether there is something wrong with the connected
device.
• Check whether the external device outputs signals. (Check this especially when the external device is a
notebook computer.)
• Check that the cable connected to the external device isn't defective.
• Check that the projector is connected to the external device using the correct terminals.
• Check that the connected device is correctly selected as the input source.
• If an extension cord is being used, replace it with the supplied cable and check whether images are
projected correctly. If images are now projected correctly, add an RGB signal amplifier to the extension
cord.
Problem Solution
Projected images are shaking.
Projected images are
displaced.
• Check that the signal being output by the external device isn't intermittent.
• Connect the cable's plug with the external device's connector firmly.
• Press the AUTO button.
• Some computers output out-of-spec signals on rare occasion. Adjust the SIGNAL menu (see page 26).
Projected images are
distorted.
• Adjust the projector and the screen so that they are perpendicular to each other (see page 8).
Projected images are dark. • Adjust BRIGHTNESS and CONTRAST in the IMAGE menu (see page 24).
• Replace the lamp (see page 28).
Projected images are blurred. • Adjust the focus (see page 14 and 17).
• Clean the lens.
• Press the or button on the remote control to eliminate flicker.
• Adjust TRACKING and PHASE in the SIGNAL menu (see page 26).
• Adjust BRIGHTNESS and CONTRAST in the IMAGE menu (see page 24).
• Adjust the projector and the screen so that they are perpendicular to each other (see page 8).
White dots are seen on
projected images.
Black dots are seen on
projected images.
• This symptom is normal for a DLP projector and is not a malfunction. (A very small number of pixels may
stay lit or out, but it is not a malfunction. Pixels of 99.99% or more are effective.)
Rainbow effect is seen on
projected images.
• This is due to color breaking noise that occurs in a DLP system and is not a malfunction.
Fine streaks are seen on
projected images.
• This is due to interference with the screen surface and is not a malfunction. Replace the screen or displace
the focus a little.
Projected images become
wavy.
• Connect the plugs of the cables to external devices securely.
• Keep the projector away from devices that emit interfering radio waves.
• 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
keystone 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 D-SUB INPUT in the SIGNAL menu is correctly set (see page 23).
• Check that the cable connected to the external device isn't broken.
Only the motion areas in the
images supplied from the
computer aren't displayed.
• This is caused by the computer being used. Contact the manufacturer of your computer.
Projected images are
obscured.
• 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 36).
• Some images and texts appear obscured during the keystone adjustment. In such cases, use the projector
without applying the keystone adjustment (see page 15).
