I can't seem the get the CRT to completely light up. No matter how much I play with the ion trap or focus cool, it still on lights up the top half. Any thoughts?

Is the ion trap magnet actually good? I seem to remember encountering one where the magnet itself had cracked and most of it had fallen out.

The hv is only at 4-5k, so I'll start trying to figure out why it is low. Maybe the correct hv, around 10-11k will help this out.

It seems fine to me, I don't see any damage at all.

All I can seem to get is this curved horizontal line. I can hear the station tuned into and flickering of this line. Is it possible my vertical output transformer is bad?

Looks like your vertical deflection circuits aren't working. Instead of a full raster from top to bottom, you have the classic horizontal stripe.
Don't run it for long periods with that bright horizontal line, or it may burn a dark strip across your CRT. Have you replaced any parts on this TV? If not, caps in the vertical seem like a good starting place. Phil Nelson Phil's Old Radios http://antiqueradio.org/index.html

Yes all caps, including the electrolytics, have been replaced. And I thought this was going to be an easy set...

This is the best I can get it. Any changing of the ion trap, yoke or focus coil only makes it worse or gives me a horizontal line. I'm confused on what's happening or where to look next....any thoughts here?
