Take it apart and clean the crt. I have found that a build up of film on the inside of the plastic insulator at the front of the tube and on the glass can cause that static crackle and in turn interference in the video. Removing the crt on a CT100 is a piece of cake. Go for it.

Nice work Tom. I am in your camp about "J" hook repairs. Removing the leads from the terminal lugs is so easy if you have a pump driven de-soldering machine and you know how to wiggle and create a cold solder joint.
