projector. (See page 35.)
“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 output 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.•
When an extension cord is being used, replace it with the supplied cable and check •
whether images are projected correctly. If images are projected correctly, use an RGB
signal amplifier along with the extension cord.
Images are not displayed correctly.
Problem Solution
Projected images are
shaking.
Projected images are
displaced.
Check that the cable connected to the external device isn’t intermittent.•
Connect the cable’s plug with the external device’s connector firmly.•
Press the AUTO POSITION button.•
Some computers output out-of-spec signals on rare occasion. Adjust the SIGNAL •
menu. (See page 34.)

Afterimages persist on
the screen.
This phenomenon is improved by keeping projecting an evenly bright image. (Such •
“image burn-in” phenomenon where afterimages persist on the screen may occur if a
stationary image is kept displayed on the screen for a long time.)
Red, blue, and
green dots appear in
projected images.
Black dots appear in
projected images.
This phenomenon is unique to LCD projector and isn’t a product malfunction.•
(A small number of pixels always stay on or off, which are not malfunctions. More than
99.99% of the pixels are effective.)
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.
Vertical or horizontal streak noise may appear on the projected image, depending on •
the type of the DVD player or game console you use. In such a case, you can reduce
such streak noise by enabling the LPF. (See page 29.)
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.•
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 29.)•
Check that the cable connected to the external device isn’t broken.•
