Frequently when viewing high contrast scenes, certain parts of the image will begin to flicker or shimmer. I typically see this with HD broadcasts and some digital, mostly film content. For example when viewing white text on the screen (scrolling movie credits, text on a billboard in a movie, etc.) or when viewing an article of clothing with white or bright patterns, these patterns begin to flicker a bit. Other examples are windows on a brightly lit building, peoples jewelry or trees against a skyline. Personally this has become very distracting, I'll be focused on a main subject in the center of the screen only to have my eyes redirected to the corner of the screen by some jitter. Note that when this happens, the majority of the image is rock solid. I've tried to tame this by lowering sharpness, thinking it's too much edge enhancement but this dosen't really help. I also tried some SM adjustments (Mid 5) without any success. I know that the set is suppose to convert 1080i to 788p but there still seems to be some kind of de-interlacing, aliasing issue. I had a DLP for a while, and although it had it's variety of issues, I did not notice this effect at all. Has anyone else noticed this? Is it possible my set has some kind of problem? If so, what could it be? De-interlacer? I'm kinda set to do a service call but would rather not if this is "normal". I've posted a similar message in the past but received limited response. I'm hoping some of you newer owners can give some feedback.
