Hello , my name is ***** ***** just saw your post,

We have worked together prior to this .

Don`t have the schematic for this ctc197 chassis but I`ve worked on those more times than I can count or care to count

Won`t be able to go into full details today but we could get started anyway

Correct me if I`m wrong but right now I assume that If this happened after replacing the flyback then that transistor must be the horizontal output ?

Q14401 is the horizontal output, Q14801 I believe is in the pin circuit coming of the flyback with R14801,a 1k ohm being on the base is open

It was my experience with those chassis that you would get cold solder joints ( especially after working on it) in the horizontal deflection circuit and especially around the horizontal drive and tranfo , don`t inspect them , simply redo them all from the hor.out on down to the jungle ic pretty much.

Finally , there used to be a small electrolytic cap around the horizon drive that would go out of specs and cause the over heating of the hor. out

But again , I definitely suspect that flyback and you may be better off looking for a used ctc197 chassis and borrow its flyback even if its just for a test
