My lap top feel off the bed now the screen has dark green color on the screen and the background is light yellow. What could be the problem

What happens when you plug in an external monitor? If that shows a good desktop image then your internal display is damaged. Do you have any visible damage? Look at the hinge area is it square or visibly bent? Then you’ll need to dig a bit deeper as you may need the full lid assembly Vs just the LCD.
