You will most likely need to have the set diagnosed. Vertical lines can be the result of a defective t-con board, faulty lcd panel/t-con connections, or a faulty panel itself. Do the lines stay or do they come and go? Older Samsung sets are known for faulty LCD panels!

Vertical line in center


If the line is "vertical" then the vertical circuit sounds OK. The problem would be in the horizontal deflection.

Check yoke connection and solder around horz defl circuit.

If the line is horizontal then I would suspect the vertical IC.
