I have never written a unity shader before and lack the skills to do so at the moment, however, I am asking for advice into how to create a shader that will mimic an LCD/CRT screen.
The purpose for this shader is to apply to a computer screen in my unity scene which will be used within a cutscene.
If you want anything else, please don’t hesitate to ask and thank you in advance for your time.

Gamasutra has had several good tutorials on this subject, like this one and this one. Also, search engines are your friend. One of these tutorial is the first result when searching for “crt shader” on Google.
I recently created this CRT post-process: Unity Asset Store - The Best Assets for Game Making
I think the results are pretty good, haven’t seen anything else like it on the Asset Store.
Here are the example images:
