Why does the image have a blue cast when I connect my video equipment (DVD player, satellite receiver, etc.) to the projector using a component-to-VGA video cable?
Try the following solutions:
Make sure your component video cable is properly connected. The connectors on the cable are color-coded. The red, green, and blue connectors should be attached to the red, green, and blue component video-out connectors on your equipment.
Make sure the projector's Input Signal setting is set correctly to match the output signal of your connected video equipment.
Make sure the connected video equipment is set up to output video to component video.
