I was given a 22-inch Viewsonic monitor. The label had been scratched
off. It has four switchesd below the screen, labeled 1, 2, an up arrow,
and a down arrow.
When I plug it in, it flashes Red, Blue, Green, White at about one-
second intervals. Pushing the buttons doesn't affect it.
I haven't attached a VGA or DMI to it.
Is it irreparably broken?

Short answer--no, it's not irreparable if it's showing life.
This sounds like a power supply issue, but that's just a guess.

I wondered if it was trying to set the operating voltages (g2 voltage)
of the three electron guns by turning each on in turn and measuring
the beam current. And then failing for some reason. The fact you get
all 3 primary colours suggests the CRT is good enough to do something
but maybe not good enough for this automatic set-up to work. Or more
likely there is a fault in that system.

CRT or LCD?
Viewsonic made both. The 22" CRTs were high end and very nice. The 22"
LCDs are generally pretty ordinary.
If it is a CRT, is the face of the display completely flat?
If LCD then it might be in some self-test mode waiting for a signal.
What happens if you feed it?

Probably doesn’t matter.
This is a characteristic behavior of many monitors' “burn-in” mode.

It was apparently indeed in a self-test mode. When I fed it, it
actually worked well. When I looked at it using my video configuration
in KDE on Debian 12, it claims to be a Viewsonic VX2262wm.
