I finally got the Black and White image on the screen but still get a Fail every time I try to Calibrate. I've tried the 1920 x 1080 file from 480, 780p, 1080i and 1080p with no success. I read on the older Samsung's that there should be a small square that appears on the screen and moves around while calibrating. I never see this small square come up. On a good note, my Samsung just came directly from the factory and it seems the bright whites don't appear to make the Plasma buzz as loudly as the older manufactured ones.
