If the projector continues to overheat after you clean the air filter, the problem may be caused by damage to the cooling fan or internal circuits. Contact a qualified service person.
◗The projection lamp and power lights are flashing at the same time.
An abnormality may have occurred in the projector. Turn off the projector and unplug the power cord. Then plug the power cord back in and turn on the projector. If nothing changes, call the service center.

Problems with the Image or Sound
◗An image does not appear on the screen.
Check that the power light is on and the lens cover is off. Also make sure the cables are installed correctly, as described in Chapter 1.
The correct image source may not be selected. Press the Source button on the remote control or the control panel to choose another image source.
◗Only part of the computer image is displayed.
If the computer’s output resolution setting is higher than 1024 X 768, the projector resizes the image. If the computer output is not compatible with this resizing, choose a different display setting on the computer. In Windows 3.x, use Windows Setup in the Main program group. For a Macintosh, choose Control Panels under the Apple menu and then choose Monitors. In the Monitors screen, choose Options
