Troubleshooting
Check the following matters before requesting servicing.
* Is the power cord plugged into a power outlet?
* Is the lamp cover properly mounted?
* Is the projector’s temperature high? To protect the projector, the power can-
not be turned on when the projector’s temperature is abnormally high.
* Has the lamp reached the end of its service life?
* Is a connected input selected?
* Is the cable properly connected to the input terminal?
* When a computer is connected, are signals being output from the computer?
* Does the signal being input have a frequency usable with this projector?
* Are the brightness and contrast adjusted to the minimum?
* When the component signal of a DVD player is connected to the RGB or DVI
terminal (analog signal), if no image is produced, have you selected RGB/
component?
* For an RGB input, has the picture been properly adjusted?
* Is the projector properly installed?
* For trapezoidal (keystone) distortion, perform keystone adjustment.
* Is the lens properly focused?
* Are the screen and projector installed at the proper distance?
* Does the projection distance exceed the focusing range?
* Is there condensation on the lens, etc.?
If the projector is moved from a cool storage area to a warm place and the
power is turned on, condensation may form on the lens or internal optical
parts. If this happens, wait until the condensation has evaporated before
using the projector.
* For a computer input, are the horizontal and vertical positions properly ad-
justed?
* Does the input signal have a compatible resolution and frequency? Check
the computer’s resolution.
* If the image is crushed in the horizontal or vertical direction or if it is not
displayed over the entire screen, select a different aspect ratio.
* When a component signal is being input, is the color matrix setting proper?
* For a composite input, is the hue properly adjusted?
* Turn on the auto image adjust mode. If the auto image adjust mode is off
(manual), adjust the clock frequency and phase.
* See “When an indicator is lit or flashing”.
* Are the remote control unit’s batteries worn? Replace with new batteries.
* Is there an obstacle between the remote control unit and the projector’s
remote control signal sensor?
* Is the remote control unit outside of range?
* Are you pointing the remote control unit’s transmitter towards the projector’s
remote control signal sensor?
* Is the computer mouse mode set? Press the “PJ” button so that the button
lights red.
* Is the USB mouse properly connected? (Not all USB mouses can be used.)
* Is the Control Panel Key Lock set to [Enable]?
