Just in case anybody was paying attention to this ...

Evidently the blanking has something to do with the machine being on a
KVM switch with another computer (which happens to be a Mac Mini, but
that doesn't seem to be relevant as it was powered off).  I thought I
had ruled out the KVM before I posted the first time -- among other
things, why would rebooting the linux machine fix a failure in the
KVM? -- but the problem has not recurred since plugging the monitor
directly into the computer.

This isn't 100% conclusive because I've gone days or weeks without
this happening in the past, but it's the first time I've gotten the
problem to go away without rebooting.
