Ys, I have four of them in my workspace currently.  Heavy

Dunno.  In the past, when this has happened, I've
just swapped out the monitor for another one (I
come across these pretty often)

Yes.  Arcade monitors, in particular, are usually not
near the same level of performance, are built much
cheaper, etc.  Just accessing the boards inside one
of these monitors is no small feat (IIRC, there are
5 or 6 boards in this monitor -- surrounding, and/or
attached to, the neck of the tube -- enclosed in
a metal skin)

*Realistically*?  Probably best to just use the monitor
until you can't tolerate the black level any more and
then recycle it (please don't put it in a landfill)

If you think you can spend the time (figure at least a
solid day) dicking with it, send me model numberand
I'll look for schematics.  I suspect, though, that once
you start poking around inside it, you'll quickly
run out of time  :<  (note you will also need someplace
where you can leave it disassembled if yoou can't work on
it nonstop -- someplace "Junior" can't get at it!)
