CRT/LCD screen shader (for materials)

Question

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.

An image effect is basically just a material attached to the render output of a camera, rather than an object in the scene.

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 have already seen one of these but both of these are for image effects or post-process effects when I require a shader for a material for a single object in my scene.

Adapting those examples to work on a single object sounds like a great opportunity for learning.

I wouldn't know where to start, I have no experience with shader code

I recently created this CRT post-process: https://www.assetstore.unity3d.com/en/#!/content/80048

I think the results are pretty good, haven't seen anything else like it on the Asset Store.
