Sadly, lines are usually caused by the cable no longer having a good connection to the panel. See, modern manufacturing practices are such that nobody takes the time to actually solder wires on anymore, so they are just held on with tape! Over time this tape gets loose and causes poor connections, leading to all of the LCD screen and CCD sensor warranty repairs you have probably heard about. So the tape is designed to last just through the warranty period and contributes to the disposable, throwaway nature of modern consumer products

The usual fix is to iron the tape back on using a soldering iron and silicone pad. You can find the kits at Amazon by searching for "LCD Pixel Ribbon." It is not possible to actually solder the wires on because they are embedded in plastic. Sometimes you can fit a piece of foam behind the ribbon to apply continuous pressure when things are reassembled.

Or if you buy a new panel it will come with a freshly taped-on cable.

Let's try to isolate the issue by connecting your laptop to an external monitor if you have any. TV or other monitor can check if this is a hardware or software issue. If you have connected it to an external monitor and the blue lines is still appearing, uninstall and reinstall the graphics card driver found in the device manager of the laptop. If the issue does not persist in the external monitor then the screen or lcd of the laptop should be replaced.
