How to Remove a Line on the Tablet Screen

[sashikp]

A vertical line has appeared on the screen of my tablet. What can I do to remove the line ? The colour of the line keep changing and line is thin.

The same thing happens on computer LCD screens sometimes. It's caused by a kink when the screen is bent. Sometimes it straightens and goes away by itself. There was a video on you tube about this. On the computer, the technician had to open the screen to fix it.
