My laptop display is moving weird?

I sat on the sofa with my laptop and then my brother swung his foot out next to me and hit the right side of the display!
Fortunately nothing happened to the laptop, but somehow the right ball bearing roller (I don't know the name) does not engage!
Does anyone have any tips or can somehow show me a YouTube tutorial?
Thank you for your help!

I've already had this on several laptops, it's completely harmless as long as everything is still working

Even if there's no visible damage externally, it is possible that the hinge now has a Knax or that it has come loose in the housing and therefore has more play and is no longer properly seated. There's not much you can do about it except to swap the hinge.

Depending on how old the laptop is, you may find spare parts on eBay, but I don't know which parts of this hinge would be included, it may well be that you have to buy the entire housing again and replace it accordingly, maybe it is but also included with the display lid without a display panel.
