As for any digital appliances, breaking- downs are typical for projectors. The malfunctions of projectors are related to non-compliance with the rules of their service: physical impacts, contacts with dust or moisture. The information below from our troubleshooting table with faults` codes for Infocus projectors will help out specialist to determine and remove the cause of a breakdown, as projectors are very complex appliances.
| Problems | Solutions |
|---|---|
| Problem: Nothing on projection screen | • Make sure that the power cord is properly connected to a functional AC electrical outlet. Make sure that the power cord is also properly connected to the projector. • If the projector is plugged into a power strip, make sure the power strip is turned on. • Make sure you have removed the lens cap from the projection lens at the front of the projector. • Make sure the projector is switched on. • Check the projector’s lamp to ensure that it is securely connected in the lamp module. |
| Problem: Image not being projected | • You might need to adjust the brightness or contrast until the image is visible. • Verify that the appropriate input source is selected. |
| Problem: Image from VCR does not display properly. | • Make sure “DVD Optimized” is turned off in the Image menu. • Adjust your VCRs sharpness control, if available. • Adjust the projector’s contrast control to perfect the image. |
| Problem: Image from source using S-video does not display. | • Press the Video 1 button on the remote to toggle between composite video and S-video. |
| Problem: PAL video does not display correctly. | • Select PAL from the Video Standard options in the Controls menu. |
| Problem: Image has noise on the edges. | • Turn on Overscan in the Image menu. |
| Problem: Image seems stretched from top to bottom. | • Your video is in anamorphic 16x9 format. Press the Video 2 button on the remote to toggle between 4x3 and 16x9 formats. |
| Problem: Image looks too red or blue. | • Change the Color Temperature. See “Color Temperature” |
| Problem: no sound when no external speakers connected | • Press the mute button. • Adjust volume. • Verify audio/input connections. Make sure external speakers are connected, as the projector does not have internal speakers. • Adjust audio source. |
| Problem: Only the start-up screen displays | • Verify that the cables are connected correctly. Check to see that the CableWizard computer cable is correctly connected to the monitor connector on the computer (this is the connector where your monitor cable usually goes.) • Verify that the proper input source is connected. • You might need to turn everything off and power up the equipment again. Make sure you power up in this order: projector, computer monitor, computer or video player. It is especially important that you follow this sequence for Macintosh computers. • Make sure your computer’s graphics board is installed and configured correctly. Also check the following: • Does your computer have a compatible graphics port? The projector isn’t CGA or EGA compatible. • Is your computer’s graphics board turned on? This is especially true for laptop computers. |
| Problem: Computer image isn't centered on the screen | • Reposition the image. • If you’re using an extension cable between the Cable Wizard and the projector, make sure it’s InFocus-approved. |
| Problem: Image is too wide or narrow for screen | • You might need to manually adjust the tracking to reduce or enlarge the projected image. • Adjust the resolution of your monitor if it’s greater than 1024x768. Only these resolutions at 75 Hz or less will display on the projector. |
| Problem: Image is out of focus | • Turn the projection lens to focus the image. • Make sure the projection screen is at least 4 feet (1.2m) from the projector. • Make sure the projector is turned off, then check the projection lens to see if it needs cleaning. |
| Problem: Image and menus are reversed left to right | • Rear projection mode is probably turned on. Switch back to forward projection from the Controls menu. The image should immediately return to forward projection. |
| Problem: Image and menus are upside down | • Ceiling mode is probably turned on. Turn off the mode from the Controls menu. The image should immediately return to forward projection. |
| Problem: the projector displays vertical lines, "bleeding" or spots | • Adjust the brightness. • Make sure the projector is turned off, then check the projection lens to see if it needs cleaning. |
| Problem: The screen resolution is not right | • Make sure the computer’s graphics card is set for a resolution of no greater than 1024x768. |
| Problem: Image is "noisy" or streaked | Try these steps in this order. 1. Deactivate the screen saver on your computer. 2. Turn Auto Image off and then back on again. 3. Adjust the synchronization and tracking manually to find an optimal setting. • If you’re using an extension cable between the CableWizard and the projector, make sure it’s InFocus-approved. • The problem could be with your computer’s graphics board. If possible, connect a different computer. |
| Problem: Projected colors don't match the computer or video player's colors | • Adjust the brightness, tint and/or contrast from the Display menu. Just as there are differences in the displays of different monitors, there are often differences between the computer image and the projected image. |
| Problem: Lamp seems to be getting dimmer | • The lamp begins to lose brightness when it has been in use for a long time. Replace the lamp |
| Problem: Lamp shuts off | • A minor power surge may cause the lamp to shut off. Turn the projector off, wait at least 30 seconds, then turn it back on. |
| Problem: Remote not operating correctly | • You might need to replace the batteries. • Make sure you’re pointing the remote either at the back or front of the projector, or at the projection screen. • Make sure the remote is within its operating range of 40 feet. |
