Wow.... a little optomistic with your following statement....
"I'm no TV repair expert, but it seems this one should be relatively easy,
if I had a schematic."

Take the hot OUT of circuit and test it to make certain it is not
shorted.... your statement "it didn't seem to be shorted" does not inspire a
lot of confiedence. Be aware that the HOT can fail and not neccessarily
show a direct short on your meter... it can have fatal CE leakage that won't
show up as a short.
...... and check the bridge, you should know for certain that it is good and
not that it "appears to be fine."
Check the B+ voltage regulator and/or replace it and also for shorted/leaky
filter caps in the the raw B+ and the regulation circuitry. Also check for
shorted caps and faulty diodes in the flyback derived B+ circuitry.... all
of this is relatively easy to find without a schematic.

ps.com...
I have a Sony Trinitron from 1989, model KV-20TS10. The main fuse was
blown, so I put in another and plugged it in. Within a few seconds I
heard the power relay click (it turned itself on) and the fuse blew
immediately. Not enough time for audio, picture, nothing. I did a
quick check of the H.O.T. in-circuit and it didn't seem to be
shorted. The bridge rectifier appears to be fine. I'm no TV repair
expert, but it seems this one should be relatively easy, if I had a
schematic.
Are there any common problems with this set that causes this symptom?
