Black line in the middle of the laptop display?

I started the laptop and it was a black line in the middle of the screen to see. I do not know where it comes from. Do I need a new display or can I fix it differently?

If I need a new disply, I would need left where I can buy this and the instructions for installation.

Maybe the display is cracked if it's cracked then you can't do anything. Either install new display or buy new

Is not cracked but it is just a black line.

he is fat and it is probably black pixels, so I have to change so

Yes the display inside is broken you have to change

Let that look at a technician before. Maybe that's a mistake he already knows from your model. It does not necessarily have to be the display. The flex cable to the display can also be defaced, worn through.
