Yup, that would do it.

foldover in the middle and a hot running horizontal output transistor are an indication of insufficient drive to the transistor. Look for the wire going to the base of the horizontal output transistor and trace it back to the driver transformer. Connnected to the other end of the transformer winding should be a capacitor and resistor. The cap is probably dried out (open) and this overheats the resistor. As these parts fail, the horizontal output overheats and shorts.
Can you post the horizontal portion of the schematic?

Replaced capacitor closest to the horizontal board transformer. Picture shows red and still folds in the middle. Capacitor was a film capacitor.

Is it true a bad flyback can cause vertical fold over?

If you replace your flyback, and the foldover continues, I would say no. Replace capacitors first.
