White lines on laptop screen

Hi,


My laptop has developed a white vertical line on my laptop screen. Till last night, it used to appear intermittently. Today it has stayed on. The line appears exactly at the location of left side hinge.

Is it a hardware issue or a software one? Will the screen need replacement?

Any idea?

Please help.

Thanks!

I didn't find the right solution from the Internet.
