RCA ATC113 36" focus issue. Bad tube or flyback?

[radiotvnut]

I was given this TV by the same person who has been loading me up with BPC sets here lately. He told me it had focus problems and that he thought the flyback was bad. When I checked it, the picture is somewhat OK with the black level and contrast at midrange (although it does show symptoms of trouble).



Now, this is what it looks like when I crank the contrast to max. The picture goes out of focus and there are black bands in the picture. It sort of reminds me of what those Zenith CRT's of the 90's would do when they were going bad. He thinks it's the flyback. I think it's the CRT. What do you think?
