Gentlepeople,
I have a VR201 (DEC Pro b/w monitor). It's been stored for a while. I just noticed
that the faceplate has spots on it which don't clean off.
More precisely, it looks like they are spots (bubbles?) *inside* the faceplate coating
material.
Any suggestions for how to treat this?
There was actually an extended discussion of this about a year or two ago
here (search the archives for "screen rot", IIRC). My recollection is that
the options for fixing it were relatively unpleasant, because it involves
removing and then reapplying the implosion protection layer on the CRT.
That could be my faulty memory, though.
Yes, the effect is often called "cateracts" in the CRT world, and
they're a very common problem. There are methods for removing the
implosion protection glass and cleaning it, but I've never tried them
personally. They look relatively risky.
There is a series of videos on the subject on youtube:

Again, it looks pretty risky, and I've never tried it. So, try it at
your own risk (but if you do, tell us how it works out!)
