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.

from condensation, turn off the projector, disconnect the power
cord, and leave it for a while.
