I have a Sharp XR-1S DLP projector, bought as bankrupt stock. It plays V Good and i'm pleased with the quality of the image I get using component video from my PC & DVD via the 15 pin D-sub connection. My problem is in using the S video & composite connections, I always only get the image to be B&W, strangely when I first set up the projector the S video signal from my Phillips free view box was colour but kept breaking up when I changed channel's, but now any signal via these sockets is B&W. What am I doing wrong? Please help!
