I have a Samsung 46" DLP model number HL-R4667W. On every source, with different connection cables, there is a full-screen grid of blue flickering squares. It distorts the entire screen image and is especially noticeable over dark colors. If I unplug the source, I am left with the screen saying that there is no input detected, but the grid is gone. It's the same story with an HD signal over HDMI, with my DVD using component video, and with a game concole using plain AV or component. I haven't been able to find a single answer to this problem.
