Sony KDL-70R550A has yellow vertical line in it

[blake.s]

I have a sony kdl-70r550a that has a yellow vertical line in it on the right side of the screen. I am trying to determine if this is the panel tabs or if the t-con. T-con usual is not the issue if there are vertical or horizontal lines correct?

Attached are some pictures. You can see the right side has a discolored vertical line.

Usually holds true for horizontal lines but I've seen times when even horizontal lines were fixed with a new tcon, did you try cleaning and reseating the ribbon cables from tcon to panel? and make sure the lvds cable from mainboard to tcon is clean and secure in place, never force a connection off, if it don't come off easy something is wrong with procedure.
