Hi Barry. I've heard of such CRT "flashover" before, my father (now retired)
ran a consumer electronics repair company for many years and they recognised
it as the cause of problems when TV sets started to use digital ICs.
Inexplicable problems where serial EEPROMs would suddenly lose configuration
data etc... As far as I know the devices were not permanently damaged in
those cases though.
