My line is exactly the same as this, UE55NU7021K bought April 2019. Tried the Samsung support from the menu but no response. Have soft reset, unplugged. Software up to date. Was there any solution that can be implemented remotely?

I have the same issue, only difference is that I have two of these vertical lines.  In the beginning when there was just one the line, it would come and go on occasion, but it has been there consistently now for over 6 months. I wonder if anyone having this issue has tried replacing the break out box?  It is my suspicion that the lines are the result of a video processing issue and not an issue with the panel itself.
