From what I read the Pioneer sets had this problem either to a much lesser extent or not at all. My 2007 700U had no visible line bleed on the green preview screen. I think I had 6000+ hours on it. Besides the line bleed though, the PQ on my GT30 is significantly better my 700U. Besides the year and make of the TV, I think the TV size has a lot to do with whether or not there is noticeable line bleed. The larger the set the more pronounced the line bleed. I went from 50" to 60" so that could be playing a part. On my next TV I'll go at least 65" but maybe as large as 70" so I'm hoping the state of the art doesn't have the problem anymore when the time comes.
