It's not, it's more likely as it contains much higher voltages right on the
same logic board as the low voltage stuff, but the chance of damage is so
remote it's hardly worth mentioning, you're more likely to damage one or the
other by dropping them.

Nothing, not on a reasonably modern monitor anyway. Some of the early ones
would fry if fed an invalid sync signal, anything made in the last decade at
least will just shut down.

There isn't one, though if it doesn't boot you should disconnect anything
non essential and see if that allows it to boot.
