I think its this blasted LED tech. My CCFL based LCD from 2008 does not have it at all. But even my top of the line new Sony HX950 has the vertical band, and its an LED too. I think we can't escape it for LED sets. You have to get plasma (and then get line bleed instead and dingy white screen), or wait for OLED and get : WHO KNOWS WHAT NEW ISSUES! Yay.
