[rescue] (Possibly) dead Elite-3D framebuffer

Last night, my old HP monitor (1994 vintage; one should never use the term
"old" to rescuers. Sorry.) gave an arcing sound on power-up. At the same
time, my Ultra-60 failed to power on. It beeped, then nothing more.
Removing all the devices got me as far as the OpenPROM, where I proceeded
to run the diags. All the tests passed. I then put the framebuffer back in
and again all the tests passed, except for this:
[ ... four minutes of self-tests, all passed ...]

At this point the system hangs hard. That "can't initialize device" looked
ominous. Taking the card out again results in the box coming up as
normal, although my desktop is now a server, of c(o)urse.
So does this mean that my framebuffer is dead?
Has anyone experienced CRTs sending evil voltages back down the video
cables? -- if it does turn out that this is what happened, it serves to confirm
all my prejudices against CRTs.
Or do these units die as a matter of course? -- in which case, I'll look at
getting a new one from Feebay; I see they're selling for anything from
$25 to $120.
