Images are not displayed correctly.
“NO SIGNAL” is displayed. • Turn on the power of the connected equipment, or check whether there is something wrong with the
connected equipment.
• Check whether the external equipment outputs signals. (Check this especially when the external equipment
is a notebook computer.)
• Check that the cable connected to the external equipment is not defective.
• Check that the projector is connected to the external equipment using the correct terminals.
• Check that the connected equipment 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 equipment is not intermittent.
• Connect the cable plug firmly.
• Press the AUTO button on the remote control or AUTO SYNC button on the projector (see page 20).
• Some computers output out-of-spec signals on rare occasion. Adjust the SIGNAL menu (see page 31).
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 27).
• Replace the lamp (see page 32).
Projected images are blurred. • Adjust the focus (see page 16 and 19).
• Clean the lens.
• Press the or button on the remote control to eliminate flicker.
• Adjust TRACKING and PHASE in the SIGNAL menu (see page 31).
• Adjust BRIGHTNESS and CONTRAST in the IMAGE menu (see page 27).
• 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
TM
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
TM
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 cable plugs to external equipments securely.
• Keep the projector away from equipments 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 cable connected to the external equipment is not defective.
Tint in projected images is
incorrect.
• Check that D-SUB INPUT in the SIGNAL menu is correctly set (see page 26).
• Check that the cable connected to the external equipment is not defective.
Only the motion areas in the
images supplied from the
computer are not 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 40).
• Some images and texts appear obscured during the keystone adjustment. In such cases, use the projector
without applying the keystone adjustment (see page 17).
