Yup to all of the above. Don't forget the set was aligned with the factory caps, then you replaced them, and they all have a tolerance range, new caps respond to heat differently than the old caps that manufacturers knew was going into a tube tv. You replaced all the caps and the tolerance range will allow frequency centers to be off in all tuned circuits, so replacing all the caps most likely means several items need realignment. When I was a kid I repaired arcade games, and the guy I worked for came across a little thing he wanted to add to all his games. It was a rapid fire button. This little circuit was just a 555 ic timer that sent multiple switch closings to the "fire" circuit of the game. I mass produced a board with the 555IC and the caps, and resistors, made the thing and put them in the games. All the parts for 50 of them came from one source. When I was done, all 50 had different firing frequencies ! ! So know that your caps are most likely part of the problem. And not that you didn't buy the best, just that you changed them all, and in some set designs mentioned above, the tuned circuits will need a touch up.
