Continue to hold the display assembly with one hand, and use your other hand and a spudger to disconnect the black ribbon cable labeled "1". (Cable 1 is for the display)

Be careful to insert the spudger from the left, as shown in the picture (UNDER THE RIBBON). If you try to pry up the ribbon from the right, you could damage the ribbon connector and need to replace the display!

All connectors except the ribbon connector "3" mentioned in step 7 release upwards.
