Troubleshooting
Check the following matters before requesting servicing.
* Has the power plug become disconnected from the
outlet?
* Is the lamp cover properly attached?
* Has the internal temperature become high? When the
internal temperature becomes very high, to protect
the unit the power will not switch on.
* Has the lamp timer exceeded 1100 hours? The power
will no longer switch on once the timer has exceeded
1100 hours.
* Has the connected input been selected?
* Is the cable of the input connector properly connected?
* If there is connection to a personal computer, is a
signal being output from the personal computer?
* Has a signal that is higher than the supported fre-
quency of the projector been input?
* Check that the image adjustment brightness and con-
trast are not set to minimum.
* Has the lamp burned out?
* Is the STATUS indicator blinking?
* When a monochrome video signal cannot be dis-
played properly, set the input selection to "YCbCr".
* Is the projector installed properly?
* Is the keystone adjustment properly adjusted?
* Is the lens properly focussed?
* Are the projection screen and the projector installed
at the proper distance?
* Has the projection distance exceeded the focussing
range?
* Is there condensation on the lens and other parts?
When the projector has been stored in a cold location
and the power is switched on in a warm location, there
may be condensation on the lens and other internal
optical parts. Should this occur, wait several minutes
until the condensation disappears.
* Is the input signal being supported for resolution and
frequency? Check the resolution of your personal com-
puter.
* When the image is broken in the horizontal or vertical
direction, or the image does not fill the entire screen,
select a suitable aspect ratio.
* When a component signal is being input, the color
space setting is different. Perform the color space
setting.
