Hello I have a 55inch Samsung 16:9 hdtv (HCM5525w). Every once in a while a vertical line will show up in the center of the screen while watching a brigth scene(Like when showing a blue sky) on a dvd. I know this has ben addressed in this forum before, I would like to know what was done to fix it, if anything. Or should I just write or call Samsung and ask for a replacement. I am very happy with everything about this TV except for that one little defect. If anyone has any idea of what path to take to repair this please answer. Thanks in advance.
