As per subject. My other old CRTs go dim but all the trinitron ones go
green. Is there a simple explanation?

green does the least work.

Hmmm...

Trinitron is a single-gun tube. I would expect it to go dim rather than
having a color shift. If it goes green, maybe by losing the ability to
deflect the electron beam from stripe to stripe?
