Hi Atul,
The image and the symtom you have mentioned tell that 95% chances are there that the screen of your laptop needs to be replaced. You should have a normal 14.0 LED and you can go to any laptop service centre like [https://dktechnologies.co.in|Laptop Service Centre], who can take care of your laptop and tell your what exactly is defective physically. You can ask for free support to [https://dktechnologies.co.in/free-support/|Free Support] to get it done by yourself.
And if it is the problem with your screen, make your that your laptop hinges are ok.
Hope we could help you.
Thank you.
