Those old monitors are starting to die out.
Particularly if people assume that any one that doesn't
work can't be
repaired...
True, but if the tube or flyback goes, it's basically toast, unless
you're really masochistic.
Most of the time I agree with you, but I wouldn't condemn a non-working
monitor out of hand before doing a few quick checks to prove it's
something that's hard to get like the flyback transformer. It might be a
simple fault that you can get the parts to fix.
And there are some monitors where I would find a way to replace any
transformers that failed, as I mentioned in another message.
