@lazypersonguy attach an exteranl monitor and see if that displays properly. If it does you know you are having issues with either your LCD or the backlight circuitry. Shine a flashlight at an angle against the screen with the computer running in a dark room. See if you can make out any shapes etc. If you do, its your LED driver circuitry. If you don't it can be the LCD. Disassemble and check for damage on the motherboard as well as the display cable etc. Let us know what you find.
