OK, just so you know we are here. If it was my tv I would cycle thru the various backlight settings and see if one helped reduce the effect. Then, I would be sure to run a full screen program on the tv for a whole day and see if not using any 4:3 pic ratio helped remove the line. Then I would go from Dynamic to Standard to Movie and again, see if anything helped remove it.
I think leaving it on full screen for a whole day will give you the best possible result.
