First thing would be to take a close look at the connectors and surrounding areas for any physical damage. If you cannot see anything at all even with a clean screen and a flashlight, you may be looking at a display IC. If just the backlight goes out you can still see a faint image, but if just the display driver (u1501) or display boost (u5302_RF) goes out you can usually still see a backlight on with the screen outside of the frame. Hope this helps, but always start with the easy stuff, like looking over the board for physical marks.
