How do I tighten my LCD screen

The LCD screen on my Q8 used to be firm, so when you rotate it, the motion is stable. Now (after a fall) the screen is loose to the point that it can rotate with ease. Is there a way to strengthen the base of it so it can return to how it was? I am not certain if it is a ball at the base or a base that pops in place to re-secure it.

Please advise
