Thanks for the tips.

I donbt believe it is a TTL/ECL thing. In fact, the monitor I tried that
*did* give me something, is of the wrong kind.

No glowing on both sides. Guess that is the first thing to look. If the
flyback transformer does not produce the required voltage, it would still
glow, right?

Ah nice, I will have a look. My first attempt finding anything like this only
led me to commercial parties doing monitor repairs.
