Damaged Laptop Screen

[ilovechem]

Any idea guys how to fix this, one day when I woke up there is a flashing lines

at the bottom of my screen and it seems like getting larger the first time I noticed it is just a narrow straight line at the bottom of my screen and now it becomes a series of straight lines

I hope you could give me your suggestions and what action should I take
Thank You

First thing to do is connect the laptop to an external monitor and see if that issue is replicated on an external monitor.
If you do not see the same issue on the external monitor then it is most likely a hardware fault with your laptop screen and you should just have to replace the screen. If it DOES replicate on an external monitor, it is most likely an issue with your GPU on the motherboard, which means it is probably failing. The only way to fix that issue, if it is the GPU, is a replacement of the Motherboard.
