Hmmm. Does this sounds like the HV Diode failing to anyone else?
Screen bloom would be a drop-off in HV if memory serves. As a general
rule a preventative "cap kit" on the monitor probably won't hurt (and
re-soldering the pins on the board connectors is probably a good idea
too).

I'd give it 70-30 on the HV diode myself vs. caps, but there's plenty of
possibilties in those old monitors... ;-)
