Special Text Glow like Nightblue3

This kind of look is a composite, not just an effect. You need more than one copy of the text. Start the process by carefully analyzing the effect. What do you see:

Starting from the top and most obvious:

1. An overall glow to all of the text
2. A Text layer with:
   • A stroke around the outside
   • A TV scan line effect 
   • a glow in the center 
   • a light blue fill
3. A Text layer that is larger than the original that has
   • a slightly soft edge
   • is a little bit larger and offset down and to the left
   • the TV scan line effect is darker than the effect on the foreground text suggesting different settings but the lines are still lined up
     
   • Some variations in the edge softness that is not as uniform as a simple edge blur
4. An overall glow to the entire Text layer - suggesting maybe this is a pre-composed layer with an additional blur effect applied
5. The background

Now that you have an idea about what is going on you start to build your layers. Step 1 for me would be to load up a screenshot of the text effect for reference, make it a guide layer and lock it so you have something to refer to. Then I would be to add a text layer to the timeline, duplicate it, add a stroke to the top layer and change the fill color of both layers. The next step would be to try and duplicate the scan line effect on both layers. There are a lot of ways to do that. A good way to try a bunch of things quickly would be to take a look at some of the animation presets already available in AE. You could throw Bad TV a the top text layer and then turn off all of the effects that are applied, then start turning them on one at a time to see what you get. Keep the ones you like then see what else needs to be added. Solo the top text layer and fiddle with things like Venetian Blinds, Glow, Gaussian Blur.  This is what about 5 minutes of fiddling got me, and that is how you create composites like this.

It's not a perfect match but I'm on the right path.
