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 1,100 hours? The power will no longer switch on once
the timer has exceeded 1,100 hours.
* Has the connected input been selected?
* Is the cable of the input connector properly connected?
* Are the Picture 1 brightness and contrast adjustments (incorrectly) set to a mini-
mum?
* Has the lamp burned out?
* In the case of DVI input, has a signal other than a supported signal type been input?
* Is the STATUS indicator flashing?
* 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 angle?
* 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 resolu-
tion of your personal computer.
* 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.
* Is an obstacle located between the remote control and the remote control sensor of
the main unit?
* Is the remote control out of range for its signal to reach the sensor?
* Is there strong light or a fluorescent lamp in the vicinity of the sensor?
* Are the batteries weak? Try directing the remote control toward the remote control
sensor from a close distance and operating it. If there is difficulty in changing settings,
the batteries are weak. Replace the batteries with new ones.
* See the STATUS indicator list.
* Has the LED been set to off?
