Thin blue vertical line on the screen of UE49KU6400U TV

[Missus_grrr]

In the last couple of days a thin blue vertical line has appeared on my UE49KU6400U TV. It looks like a blue biro line and is a couple of inches to the right of centre and runs completely top to bottom of the screen.

I've done a picture test and the line remains. I only bought the set in October last year so well under warranty.

Any ideas?
Thanks
