Basically, there are 2 possibilities:
1. The connection at the back of your screen is lose, so you need to tightened this connection (usually the flex cable's connector),
2. Your laptop screen is dying, so sooner or later, you need to replace your screen.
It's either one of these things is dying: Your Screen, or Your video card You can find out which by hooking your computer up to an external monitor, and if the lines appear on it, then it's your video card. If not, then it's your screen dying. And so you can either get a new screen, or a new computer.
I know not everyone has this ability, but if you can, go to a friend's
house and hook up an external monitor to your laptop. You may need to
use the function keys to switch from LCD to external, but if the lines
go away on the external, you have a bad LCD. If the line shows up
still on the external, then your problem is either:
a) video driver (free, easy fix) b) bad inverter (video 'outputter') ...approximately $10-50/varies + labor costs to replace c) bad video card/motherboard ...usually between $200-$400 + labor to replace

Yes the problem is with your video system hardware, most likely. A repair may be possible as it could be the delicate ribbon cable that provides the video signal from a connection on the motherboard to the actual display screen. It could be the display screen. If some tech-savy friend with a good rep and an anti-static mat, good tools, and good lighting wants to assist you or check it for you, you may give that a try. Consider first that if you have or can get an extended warranty from the manufacturer then you can have a higher likelihood of a good resolution of the problem of the vertical lines that distract from viewing the display.
