Did the 2SC5148 come sealed up in a Sony bag?
Did it come from Sony spare parts if it was not in a sealed bag.

Some campanys how sell TV parts might have 2 lots of transistors one the
real on at twice the price and a cheaper version that's only good for a
short time.

I used 2SC5148, MX0841, (Original part #'s) and OEM Sony fuse res.

I did not remove the flyback, but did micro-vacuum both boards, esp
around the flyback.

I did inspect all solder joints under Bausch&Lomb stereoscope around the
HOT and flyback.

I did not check the HOT temperature after it had run for a while. I was
lazy or thought the job was done. I have an IR probe, so it's something
to check. (I don't fancy sticking my finger in there ;-)

With this additional info, any hypotheses?

Can we assume you used all Sony OEM parts?
Can we assume you removed the horizontal driver transformer and cleaned
the
connections and resoldered them?

I have a Sony KV-35S40 that will resurrect after replacing HOT, PS
driver and 0.1 ohm fusable resistor. It plays beautifully for about a
week, 3 or 4 movies, then blows. My friend saw it go, said the
horizontal width shrank to about 80-90% over a few seconds, then poof.
Any ideas?
