Got a replacement display assembly from iFixit but when I close the computer, it doesn’t go to sleep. The apple logo on the back remains lit up and the screen stays on. If I go to the Apple menu and click sleep, then close the computer, it wakes back up. I’ve reset the SMC and the NVRAM, and running a magnet over the side of the keyboard puts it to sleep. But the screen doesn’t stay tightly closed and I can’t seem to find a magnet in the display itself. The broken assembly seems to have one. Is there an easy way to move it from the old screen to the new one? Or better yet, does anyone know a way I can just get a screen that has the magnet in it already?

Let’s check to see if the Hall sensor is working correctly. Within the lid is a magnet its placement needs to align with the sensor which is just under the uppercase shell.

Using a steel paper clip slide it along the face of the screen to locate the magnet in the lid. Carefully fold the lid down to find location on the uppercase the paperclip meets up with (don’t close the lid fully) Then, place a small rare earth magnet on the uppercase so the screen goes out (sliding it back and forth), is the location the same? Did the screen go out?
