On my Sony KP-46WT510 there is a vertical line in the grey bar on the right side when I'm watching 4x3 material and a corresponding line on the left that's in the picture area. It doesn't seem to affect the picture-unless it's the cause of the green flashes on bright images-but the square test pattern on the THX test is not lined up properly. So something is definitely not lined up properly. Is anyone familiar with this problem? Is it something I should worry about or that is affecting the quality of what I'm watching? The weird thing is, I would expect for the 4x3 image to not completely fill the 4x3 area because of this--but it fills it completely. Any ideas? Any replys would be GREATLY appreciated. Thanks guys.
