Yep, it's likely to be a short, but not a simple thing like a paper
clip that fell across the power wires.

Most likely a capacitor or transistor shorted, one of the bigger ones,
like the power supply switching-mode transistor or its drivers.
When that shorts it can blow the horizontal output transistor, or vice-
versa. Plus maybe weakening or blowing out nearby diodes and
capacitors.

Worse yet, the real cause of the first transistor blowing is often yet
some OTHER part being a bit below par, something
not easily diagnosed, as it can be something subtle like a capacitor
having a somewhat high ESR. So even if you
replace the bad transistors ($$$) the underlying cause is likely to
blow them again in a millisecond or maybe a week.

And you can't just replace one bad component at a time, as the other
bad ones are likely to blow the new component toute-suite.

To do this right you need a source of gentle line voltage, like a
Variac, lots of spare parts, lots of patience.

I'd recommend you make the best of a bad situation and throw the TV
off a very tall building. Taking all appropriate safety precautions
of course.
