Troubleshooting
Before asking to have the projector repaired, try to diagnose the problem, following the
instructions below.
Symptom
The power is not turned
on.
No image.
No image/image
disturbance
The color of image has
changed.
Unintended images are
output.
On-screen display does
not appear.
The aspect ratio of the
display is not right/the
image is displayed
smaller /a portion of
image does not appear.
The image is a
trapezoid.
Remedy
Check if the AC power cord is firmly connected.
When the "Control Key Lock" is set to "On," you cannot turn
on the projector using the ?/1 key on the projector.
Check how the air filter is attached and install it securely.
Check if the connecting cable is connected to external
equipment properly.
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, the picture of the external monitor
may not appear properly. Set your computer to output the
signal to only an external monitor.
Check if the input source is correctly selected.
Check if the picture is muted.
During "Zone Black Level Adj." adjustment, a black image is
automatically projected.
Set "HDMI Cable" to "Long."
The color calibration may have been performed.
To restore the color or the factory default settings, select
"Return" or "Reset" in "Color Calibration."
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 ?/1 button on the projector or the 1
button on the Remote Commander, the pattern is turned off and
the color calibration function is disabled.
The on-screen display does not appear when "Status" in the
Operation menu is set to "Off" or "All Off."
The image may not be displayed correctly with an input signal
the projector cannot interpret correctly. In such a case, set
"Aspect" manually.
Check if "Screen Aspect" is correctly selected.
The images become trapezoidal because of the projection
angle. In such a case, you can correct the trapezoidal
distortion, using a Keystone feature.
