Troubleshooting n n n n 82 Problems with the Projector If you have problems with the projector, first turn it off and unplug it. Then plug the power cord back in and turn on the projector. If this does not solve the problem, check the warning lights at the top of the projector. These lights alert you to problems with projector operation. See the following pages for information on what to do when you see these warning lights or encounter other specific problems with the projector. qThe operation indicator is flashing orange and you cannot turn on the projector.

Problems with the Projector n n n n n n 83 qThe temperature indicator is red. The projector is overheating, which turns the lamp off automatically. Let the projector cool for a few minutes, then turn it back on. Make sure nothing is blocking the ventilation vents. The air filter may be clogged. Clean it as described in Chapter 5 and then let the projector cool for a while. 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. ¨ Warning: Except as specifically explained in this User’s Guide, do not attempt to service this product yourself.
Troubleshooting n n n n 84 Problems with the Image or Sound qAn 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. qOnly 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 and make sure Macintosh Hi-Res Display or another 1024 x 768 display is selected. For supported display settings, see page “Supported Monitor Displays” on page 89, 90. You also may need to modify existing presentation files if you created them for a different resolution. See your software manual for specific information. qThe message NO SIGNAL is displayed. An image source not connected to the projector is selected, the signal is not being output from the computer, or the signal is not reaching the projector. Make sure the connectors are securely attached to both the projector and the image source. Then check that the image source is selected correctly. When NO SIGNAL is displayed, you cannot access the source (computer/video) menu.
Problems with the Image or Sound n n n n n n 85 qA blank screen is displayed. The computer signal cannot be interpreted by the projector. Verify the display format (see page 89, 90). When you see a blank screen, you cannot access the projector menus. qThe image or parts of the image are blurred or not in focus. Adjust the Brightness and Contrast settings on the Video main menu. If you’re viewing a computer image, also try adjusting the Comp Tracking and Comp Sync buttons on the projector’s control panel. There may be dirt or smears on the lens. Clean the lens as described in Chapter 5, “Maintenance.” qThe colors of the image are not right. The color balance may be incorrect. If you’re displaying a computer image, adjust the red, green, and blue settings in the Video menu. If you’re displaying video, adjust the color and tint (NTSC only) settings on the Video menu. qThere is no sound. First check that the volume setting is not turned all the way down and that the audio/visual cable is securely attached to both the projector and the audio source. The wrong source is selected. Press either the Computer or Video button on the remote control or control panel to select the proper source.
