TV is a few months old. We periodically see a thin green vertical line just to the right of screen center. It isn't constant, and can appear regardless of video source (Netflix, which involves no cables, TV or Blu-Ray). Even though it can appear when no HDMI cables are bringing the image to the TV, I've tried swapping those cables out. I have not tried a hard reset on the TV yet. Any suggestions? I've attached a link. The line is visible on the left side of the woman's face.
I called the warranty support number earlier this week; they are replacing the TV. And hats off to Sony -- they aren't replacing it with a refurb; I'm getting a brand new TV and a slight upgrade from this one. I've marked your response as the answer even though it wasn't really, so the issue could be closed.
