Our RT's monitor, IBM 6155, has become very dim. One could suppose
CRT deterioration but it doesn't seem likely for a 1986 monitor. 
Any troubleshooting hints or schematics will be greatly appreciated.
Is this monitor compatible with any industry standard, BTW?

They do that.  The 6153 monitors do, too.

The tubes do seem to be somewhat prone to burning-in
when they're left on continuously, but my guess is
that this is a different problem.  IBM always just
replaced monitors when we complained that they were
dim.  Somebody who really understands TV sets might
be able to suggest a fix.

Not that I know of, but I don't know much.  If your
monitor becomes unusable, you can run an ordinary
EGA card and monochrome monitor (but no X-windows).
