My 13 inch Macbook's (2015) screen is half black
I take really good care of my macbook which is why Ive had my macbook since early 2016; there is no sign of physical damage and it has been working normally up until now. When it is turned off you would not be able to tell that its faulty. But when turned on, the left side of the screen is black and when you look at it (while it's on) it looks like the screen has a crack, but when it's turned off it looks perfectly fine and you can't see any physical damage to the screen. Does anyone know what i can do to fix this? I would really like to avoid having to pay to get it repaired if possible, as I am currently out of a job and have no stream of income at the moment. Below are two images; one when the macbook is turned off and one where it's turned on. The image where its turned off you can't see any crack, but the image where it's turned on you might have to zoom into the image a bit to see the crack that appears when the macbook is turned on.
