Hello. Far from being an expert and I never troubleshoot these circuits. Yet.

Couldn't it be that they need a higher voltage to ionize? It was the case with a B5094 (symbol Nixie) that doesn't spring to life unless it sees to 210V, but it glows at the HVAC test. If you disconnect the anode resistor and the whole board is left "floating" there should not be induced current and/or a closed circuit to be damaged. Unless your tester is very powerful: with mine I have to touch the glass to get the glow. What is less risky? Higher voltage or the wireless neon sign tester?
