Troubleshooting
Remedy
Check if the AC power cord is firmly connected.
When the "Panel Key Lock" is set to "On," you cannot turn on
the projector using the ?/1 key on the projector.
If the lamp or lamp cover is not attached securely, the projector
cannot be turned on.
If the air filter or air filter cover is not attached securely, the
projector cannot be turned on.
Check if the connecting cable is connected to external
equipment firmly.
Check the computer signal is set for output to an external
monitor only. If you set your computer to output to both the
computer's display and an external monitor, the external
monitor image may not be displayed properly. Set your
computer to output to only an external monitor.
Check if the input source is correctly selected.
Check if the picture is muted.
The on-screen display does not appear when "Status" in the
Operation menu is set to "Off."
The image may not display correctly because the input signal
cannot be judged correctly. In this case, set Aspect manually.
The images become trapezoidal because of the projection
angle. In this case, you can correct the trapezoidal distortion,
using a Keystone feature.
The settings for "Brightness," "Contrast," and "Lamp Mode"
affect brightness of the image. Check if the value is
appropriate.
The image will be dark when the lamp is burnt out. Check
"Lamp Timer," and replace the lamp with a new one if
necessary.
"With Static Signal" is set to "On."
During picture muting, the lamp is dimmed to reduce power
consumption.
When video signal is not input, the lamp is dimmed to reduce
power consumption.
When the lamp is dimmed for a long time, brightness may
increase temporarily, but this is not malfunction.
