Hi, I just got the new Sony 40" XBR800 direct view set. What a beast! I'm glad they send big delivery guys! Anyway, after hours of tweaking and doing the Video Essentials changes, I am pretty satisfied with the picture. My geometry looks great to me on all the test patterns, my overscan is between 3-6% everywhere, and on progressive DVD and good laserdiscs the picture is stunning - except for 2 things. On an all-white or all-light-gray screen, I am seeing that the top-right corner looks somewhat blue - enough to be annoying when white screens are up. And also that the far left has a barely-noticeable vertical streak that is a little bit darker, with it making a funny pattern near the top of the streak. Here is a simulation of the problem, where I have greatly exaggerated it: What causes these problems? Can they be ISF'ed out? It is not noticeable at all when there are "normal" scenes, just very bright-white scenes like a bright daylight, etc. If it can't be ISF'ed out, do you think that it is worth going thru the exchange hassle, especially considering I got one with no geometry problems (at least none that I see)? Are these problems inherent in the XBR chassis? Also, is there a particular test pattern on either Video Essentials or Avia for checking convergence? I would like to check that too. One other note - analog cable was *horrible* right out of the box, but with lots of patience, tweaking, and some good DRC advice on a Sony forum, I was able to make it look really good, where only the weakest signals look a little snowy/fuzzy. So for those of you with the new XBR's crying over your analog signal - don't give up hope! Just tweak, tweak, tweak! Thanks for any help or feedback on this problem.
