ballpark, well-in-theory, kind of answer.

I had a tenant say that her TV was "destroyed" (I don't know what
that
means exactly) and that the fire department said that it was "bad
wiring" in the house, and that we need to bring in an electrician
to
fix it. It's perfectly plausible that the wiring is bad - it's an
old
house, and the previous owner did DIY work on the wiring and messed
a
few things up.

So I'm wondering how would "bad wiring" cause a TV to get
destroyed?
I've never heard of this before.

Yep, it can happen. The scenario would be a poor neutral connection so
that a 120 volt on one 'phase' may be significantly higher or lower
than the 120 while the 240 to the oven or AC unit is fine.
