@smitthakkar okay. what you have here is a broken LCD. There is no repair for it but you have to replace the LCD. Take the back cover off and check the label on the back of the display. That will give you the manufacturer and the exact panel number. Use those numbers to search online for a replacement. These are not easy to find new but you may get a use one. Check places like ebay etc and see if there are any around. You can also try an find the same monitor as yours that is broken, other than the screen. You can then harvest the screen from that.
