I Have a SharpXR-1S small portable PJ. I am very happy with it, and it performs brilliantly with component/SVGA signals via the 15pin D Sub. BUT I have a problem, erratically for no reason at all, when I am using SVHS or composite video inputs the image is B&W. I don't know why this happens, It worked perfectly for 3 or 4 days, I did not change any of the settings and now it is B&W again. If I feed the signal via my PC>Graphics card>SVGA it works, but I wan't to feed it direct. PLEASE is there anyone out there who can help, I have E Mailed Sharp and they replied and mentioned the Y / H sync ?, but why does it work sometimes and not others? Does any one else have this problem ?
