When I open my macbook pro 2016 with a small angle, like less than 30 degree, the screen will light up normall. But when I try to open it more, the screen will starts getting darker with some gratings on the bottom of the screen. After the angle turns to 60 degree, the screen turns black completely. But everything else works fine, including sounds, keyboard etc. I am new here, don’t know if anyone can see my thread. I wonder it could be some kind of screen flat cable issues? Should I try to replace the flat cable myself ? (The only thing I did like this is I replaced my android phone’s camera)

Either a delaminated backlight sheet or kinked display cable You have to replace the entire top half of the computer, this thing is not repairable down to the details.
