January 6, 2016 appears to be the ship date and the cause is usually board, connection or panel. All cost a lot to repair/replace. In fact Sony usually replaces if it's a panel issue.
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 provided a link to a photo. The line is visible on the left side of the woman's face. Link to image
