Picture
On-screen display
Symptom
Remedy
The power is not turned on.
Check if the AC power cord is firmly connected.

Check how the air filter is attached and install it securely (page 51).
Symptom
Remedy
No image
Check if the connecting cable is connected to external device properly
(page 8).
Check if the computer signal is set for output to an external monitor. If you
set your computer, such as a notebook computer, to output the signal to
both your computer’s display and an external monitor, an image may not
appropriately displayed on the external monitor. Set your computer to
output the signal to only an external monitor (page 16).
Check if the input source is correctly selected (page 16).
Check if an image is cut off (page 7).
During “Zone Black Level” adjustment, a black image is automatically
projected (page 34).
No image/image disturbance
Set “HDMI Cable” to “Long” (page 31).
The color of image has changed.
The color calibration may have been performed.
To restore the color or the factory default settings, select “Return” or “Reset”
in “Color Calibration” (page 29).
Unintended images are output.
The color calibration may be being performed.
While performing the color calibration, the color calibration pattern is
displayed automatically. Wait until the pattern turns off after completing the
color calibration.
When you press the
/
key on the projector or the
key on the Remote
Commander, the pattern is turned off and the color calibration function is
disabled (page 6, 29).
Flicker in the screen occurs.
Flicker in the screen may occur transiently due to switching signals, but it is
not malfunction.
Symptom
Remedy
On-screen display does not appear.
The on-screen display does not appear when “Status” in the Operation menu
is set to “Off” or “All Off” (page 30).
The aspect ratio is not correct./An image is
displayed smaller./A part of image does
not appear.
The image may not be displayed correctly with an input signal the projector
cannot interpret correctly. In such a case, set “Aspect” manually (page 27, 28).
Check if “Screen Aspect” is correctly selected (page 34).
The image is a trapezoid.
The images become trapezoidal because of the projection angle. In such a
case, you can correct the trapezoidal distortion, using a Keystone feature
(page 6, 18, 33).
Edges of the image are cut off or dark.
If you use the lens shift function over the recommended lens shift range,
edges of the image may be cut off or appear dark. Use a setting within the
normal range for the lens shift function (page 58).
The image is distorted.
Warping is set. Disable the warp correction feature (page 19, 33).
