That is almost certainly vacuum fluorescent. There are a lot of such
displays that use the same kind of seven-segment number formation you
commonly see with LEDs.
There may exist, today, LEDs that produce blue-green light. I'm fairly
sure there weren't any in mass-market consumer electronics (even fairly
specialized devices) back around 1970 - quite likely not any at all
back then.
Not that that helps much with your question, since I am not competent
to comment on fixing either kind of display. But it may help to know
what you're dealing with.
