hopefully the pics capture it correctly, this just popped up out of nowhere on a tv only a couple years old. it's like the backlight is bleeding through almost in a straight line in the middle of the tv. no it's not the source, it's present in the menus of the tv, it's up to date as well. ive played with the backlight settings, nothing seems to help. it's not visible on black background as much as it is on white.
