Did you try reversing the ion trap magnet so the other end points to the front of the set?

This trap is the same no end is any different then the other. Would this make any difference?

Yes...I always mark an arrow on the trap pointing to the front before it is removed so I can put it back correctly.

Single magnet traps may work better with one end facing the screen VS the other (I've seen this effect in action)...It's worth trying.

Ok you guys can laugh, big screw up I had been turning the wrong pot for brightness and now that I got the right one turned it up and was greeted with a perfect pic also found the sweet spot for the ion trap.

Always good to take a step back, and do a sanity check... I've made hair brained mistakes like that before. Reaction varies from damnit when I spent minutes finding it to elation on a mystery problem I'd been chasing for months (early in my TV work).

Is that using the original CRT?

Yes I'm using the crt that came with the set although when I first checked the crt the reading was high but when I tried it a few days later the reading was lower but holding. Got Alittle buzz in the audio I have to find which can it is to adjust it out.

Ok the voltage is at 8.35 volts at the crt using a 49 ohm resistor across the heater. 52 , 56 , ohms the crt voltage is to high lower then 49 ohms is to low so this was as close as possible. 42 ohms were around 7.3 volts. So I settled on the 49 ohms. I also took out the 10 ohm power resistor and replaced it with a 22 ohm because of the diodes. B+ is 265 v the norm is 255 v so I think is close enough. Just have to find which can to adjust to remove a buzz in the audio and find out why the top of the screen is like a bright line across like on modern tvs the wide screen ends befor the top and bottom but it's the top that is bright on this set. It might be verticle.

Any clues what would cause the white line across the top of the screen I think it's verticle but checked resistors and changed all the caps and stumped at this point.
