Re: vertical output stage

Electronics fail. You might want to post the make, model, and age of
the tv set.
If the tv was more than a couple of years old, it was probably just a
coincidental failure when the tv was turned on.

Most electronics fail at turn on when it is a random semiconductor
failure.

Other things like weak capacitors in the vertical circuit that were
neglected to be repaired when the image first started to change will
generally cause a run time failure. Happens in the middle of the set
running. Other components like coils, transformers, etc also can fail
in this way.
