OK here is the deal. This is a Golden Tee that was purchased and at the time there was just a horizontal blue line across the screen but there was neck glow.

I have done a cap kit and replaced the fly. When I put it back in there was blank screen and no neck glow. A ticking sound coming from the chassis. No B+

Pulled the HOT and it was shorted so I replaced it. I reinstalled the chassis and got this a white vertical line (see picture).

It was like this for a few minutes and just as I was going to read the B+ voltage again it went dark and I am pretty sure I blew the new HOT.

Anyone have any ideas?

Thanks.

Well.

After shotgunning a bunch of parts I have this. I am not sure what I did but I am missing the left half portion of the screen.

What would cause this?

when you replaced the fly....did you re-install the wire around the iron core of the fly? If you did, you may have installed it in the reverse direction which would cause you to lose the picture on the left of the screen.

I thought I did. Its easy enough to switch it to see what happens.

Can a different fly have a reverse field on the iron core making it a 50/50 shot how the black wire goes?
 
it's the wire

99% it's that stupid black wire reverse it and you will be good. Your lucky and found the answer early, I didn't know what was wrong and ended up ruining my chassie trying to fix it when that was all that was wrong.
