Line faults & possible causes to LCD screen is given with illustrations.
What is happening to your laptop is the power line connecting a row of pixels is failing so only partial colors are showing up causing the vertical lines. Usually screen replacement is the only answer to fix it. You can usually find replacement LCD on Ebay.
Usually when there are colored lines on the LCD its because the screen is going bad. Quick way to verify this, try a different monitor on your computer and if the line goes away then you know for sure the monitor is bad.
If you try a different monitor and the line remains then you know that the video card is bad.
It is called "Thin vertical lines" and change colors depending on the background color. It is fixable but there are several components that can show this sympton.
You will need a tech to fix it in order to save money (because you do not want to buy a board you dont know if will fix it). Possible Solutions: Replace Timer Control Board, if it is not fixed Replace Sustain Board.
One of those boards needs to be replaced and I wrote the most likely first.
The thin ribbon that connects the board on the back of the lcd screen to the front glass of the lcd screen got damaged.
It wraps around the top of the screen and is very thin and can be easily damaged.
May be from old age and heat at the top of the screen or it could have gotten hit at the top.
The cheapest way to repair this is to replace the lcd screen with a
good used one because trying to find a shop to try to repair it would
cost more than a new monitor. It will change color with different colors and also if you push the screen at the top point. Don't play with pushing the screen too often as this may cause more to show up.
Sorry there isn't an easy fix to this.

Unfortunately the LCD is going faulty.. one or more of the "Driver" transistors that operates the LCD elements RGB, have faulted ON.. perhaps this link may help fix it. Otherwise :(

I know I have seen thin lines in the past on older CRT monitors, these are usually wires which support the aperture grill.
LCD is just a panel so this must be something different. What color is the line? It is probably an error in the scanning process.
