Question Display not working properly, weird colors

[skyfall09]

let me start by saying that this is my first post in this forum and I hope this is the right place to ask this question, since I'm not talking about a desktop computer. If it's not, sorry in advance.

The problem is, sometimes my display gives me some problems, it goes "darker" and doesn't show correctly the colors. If the problem persists for more than a couple of minutes, it starts overlapping the screen (if it makes any sense? I'm not a native speaker lol).

To make you understand the problem better I posted a video:

So as you can see, by applying pressure on that specific place the display starts working again.
Here is a better image of where I apply pressure with the finger: https://ibb.co/w789ykB

Any idea what the problem is? Should I just buy a new display?

I put some scotch tape on the thing I was pushing on and for now it's working. (which is something I did already but after a couple of days the problem arose again )

Tomorrow I will see if I can tighten the screw a bit more, thank you for the reply!
