If the lines extend top to bottom and are thin, then the LCD panel is most likely defective.

SOURCE: vertical coloured lines down right

No, gas problems would have generated failures all over the screen, not in distinct lines.
No, these lines are caused by badly functioning buffer boards: the chips on it that directly control those specific lines of pixels overheat and start to malfunction. The problem is getting worse because the status of the chips is getting worse: they need less and less time before starting to fail. In the end it will fail for good and those lines will be permanently on the screen.
The faulty buffer board will have to be replaced. You should call a repairman to do it - to access them the entire tv must be completely dismantled and this is a very tricky operation in a plasma tv. On top of that the replacement board is very hard to obtain by a regular person, it will have to be ordered at the dealer. Fortunately it's not an expensive part - less than $40 per piece.

To isolate the issue, i strongly recommend to connect the notebook to the external monitor by VGA port which had BLUE colored on the notebook. So that if it is normal then you need to confirm the issue is with the LCD display.

This is most likely a convergence problem. You should see 2 large black ICs in side attached to a heatsink. They will be marked STK392-010. Try resoldering the pins on these ICs first. If that does not resolve the problem, replace them. These parts will be about $20 each.
Keep us posted.

The only other thing that can be done to check that it's not a software problem is to go to my computer>right click>properties>hardware tab>device manager and look down the list for 'Display Adapters' and click the '+' sign and right click and select uninstal. Restart the laptop and the graphics adapter will be installed automatically and the driver installed. see if there is any change. To find out if it is a driver fault, press F8 on startup and select 'Start Windows In Safe Mode', this will boot the laptop without the graphics driver (VGA mode,all the icons will be large sized), so if the screen stays the same you know it's not the driver. If none of above fix the fault then the screen is faulty.
