Laptop screen turned black always for 2 years

@siddharthc41066 it turns black or it is black. If it doesn't show anything you want to try and connect an external monitor to your laptop. If that monitor works, then you know you most likely have a bad LCD in your laptop.

Of course, there is also a chance that this is a bad backlight. Either he backlight failed in your screen or you have a bad backlight driver or blown backlight fuse on your laptop. A simple check for that would be to darken the room and turn the computer on. Then use a flashlight and angle the light at the screen on different areas. If you can make out your desktop etc. then it is a bad backlight.

Since iFixit does not yet have a specific guide for that, use the video from here

While you work on your laptop, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has a device with the same issues as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
