To hot to touch most likely bad FBT or rectifier off it.
If cool or a little warm turn up variac & see if things improve.
The amps sometimes fall as the AC volts go up.
Keep in mind the HOT can short again if not careful. My advantage
doing this was knowing what I could get away with !

When I stop fighting with that trinitron project I'll try this.

I'm starting to wonder if something isn't getting enough power in the set. With the Samsung at 90vAC it looks like the trinitron screen at around 50ish volts. I'd suspect caps but they've all tested good so far. Dang TVs are a challenge compared to other electronics.
