Troubleshooting

Check Remedy
(Only when projecting computer image sig-
nals)
Are the image signals being output to the
projector?
Change it so that the image signal is set to external output, and
not just the computer's LCD monitor. For some models, when
the image signals are output externally, they no longer appear
on the LCD monitor.
For the computer's specifications, see the documentation sup-
plied with the computer.
If the connection is made while the power of the projector or the
computer is already turned on, the Fn key (Function key) that
changes the computer's image signal to external output may not
work. Turn the power for the computer and the projector off and
then back on again.
Images are fuzzy or out of focus
Check Remedy
Has the focus been adjusted? Adjust the focus. s p.29
Is the lens cover closed? Open the lens cover.
s p.26
Is the projector at the correct distance? Check the recommended projection range.
s p.17
Has condensation formed on the lens? If the projector is suddenly taken from a cold environment to a
warm environment, or if sudden ambient temperature changes
occur, condensation may form on the surface of the lens, and this
may cause the images to appear fuzzy. Set the projector up in
the room about one hour before it is used. If the projector is wet
from condensation, turn off the projector, disconnect the power
cord, and leave it for a while.
Interference or distortion appear in images
Check Remedy
Are the cables connected correctly?Check that all the cables required for projection are securely
connected.
s p.19
Is an extension cable being used? If an extension cable is used, electrical interference may affect
the signals.
(Only when projecting computer image sig-
nals)
Are the Sync. and Tracking settings adjusted
correctly?
The projector uses automatic adjustment functions to project at
the optimum status. However, depending on the signal, some
may not be adjusted correctly even after performing self correc-
tions. If this happens, adjust the Tracking and Sync. settings
from the Configuration menu.
s Signal - Tracking/Sync. p.66
(Only when projecting computer image sig-
nals)
Is the correct resolution selected?
Set the computer so that the signals being output are compatible
with the projector.
s p.96
Part of the image is truncated (large) or small
Check Remedy
Is the correct Aspect selected? Select the aspect mode to match the input signal in Aspect from
the Configuration menu.
