1. Make sure that the cables are securely connected, and that the video source is good. 2. Reset the projector to factory defaults. To do this, press the Menu key on the projector keyboard. Go to Main > Settings > Service > Factory Reset. All settings except language revert to default. Note that if your projector is mounted on the ceiling that you need to flip the image again. 3. Try fine tuning the picture. Press the Menu button on the keypad and navigate to Basic > Setup > Picture. Set the Application setting to Home Theatre. You can also try working with the Tune and Color Temperature settings. The top or the bottom of the image is wider than the other. ("keystone" problem). 1. You can correct for keystoning by making sure the projector is placed perpendicular to the viewing screen. Raise or lower the elevator foot on the front of the projector to obtain a rectangular shaped image. It may be necessary to place the unit on a higher surface to correct the image. If the sides are uneven, the projector is angled slightly. 2. Press the Keystone Up or Keystone Down button on the projector keypad to digitally adjust the image. Use this method when you cannot solve the keystoning issue by changing the projector placement. You can also adjust keystone in the Basic menu. Press the Menu button on the keypad or the remote, then navigate to Keystone. Press the Select button on the keypad, then use the right and left arrows to adjust the keystone setting. The projector will not lock onto a black and white image. The projector requires a 'burst' of color to lock onto the video. True black and white video does not contain any color information for the projector to use for synchronization. The image appears to be stretched vertically or horizontally. The Aspect Ratio is not set correctly. When you project an 4:3 image (typical television width to height ratio) and have the projector aspect ratio set to 16:9, the image looks stretched horizontally. Conversely, a widescreen (16:9) image shown in 4:3 will appear to be stretched vertically. To change the aspect ratio, press the Menu button on the keypad, then go to Main > Picture > Aspect Ratio. Select Native, 16:9 or 4:3. Note that this issue applies only to video images. Computer images always appear in the 4:3 format. The LED on the projector keypad is blinking red. No image is projected. What is wrong? The C40/C50 has an LED next to the Power button. It shines green or red, depending on the state of the projector. The LED can help you troubleshoot projector problems. Your User Guide contains a detailed description of the LED error codes. I'm playing a DVD from my laptop, but the projector is just displaying a blank screen. This happens when the laptop does not have the resources to display the DVD in two different places at the same time. To project the DVD, disable the internal screen on your laptop. Press and hold the FN key on the laptop and then press the appropriate function key (F1, F2, F3, etc.). The key will be labeled "LCD/CRT" or the monitor icon. (Refer to the laptop activation chart or your laptop documentation for further video port activation instructions.) Is the image that the C40/C50 projects progressive or interlaced? Will the C40/C50 projector show only a progressive image no matter what the input is? No. The final image in the C40/C50 depends on the input. For example, an image in the 1080i format will be projected as an interlaced image. How many video lines can be displayed on the C40/C50? The number of video lines depends on the video source. The number of lines output on DVD players may vary from one manufacturer to another (from 400 to more than 1000). Through the RGB input, the C40/C50 is capable of displaying between 400 and 1050 active line count – non-interlaced. How do I show broadcast television on the C40/C50? The C40/C50 is capable showing broadcast images as long as you can connect the projector to a cable/satellite/Direct TV converter box. Some of these boxes have composite and/or S-Video connections. If you do not have a converter box or if your converter box does not have a video connector, you can connect it to a VCR (or DVD with a built in tuner). Then connect the appropriate cables between the video out plugs on the VCR and the video in plugs on the projector. For a more complete explanation of what signals the C40/C50 can accept, see the C40/C50 Video Connections Chart. How do I show DVD and VCR movies on the C40/C50? Connect the projector to the VCR and DVD player that has an S-Video or Composite connector. S-video provides a better image than composite video. For a more complete explanation of what signals the C40/C50 can accept, see the C40/C50 Video Connections Chart. Can I use the C40/C50 to play video games? Yes, most game consoles include a cable with an RCA video connector or an S-video connector. Either is compatible with the C40/C50. S-video provides the best image. For optimal sound, you will want to run the audio signa...
