I had one of these evaluation kits, and I recall that the displays were socketed. If you have an oscilloscope, you should do some basic debugging. I would start at the power supply (one of my nixie clocks used a Signal Transformer of the same vintage that died due to an open primary). If you have all the proper dc voltages, I would next check the logic level signals: the 60 Hz reference and the MUXed segment and digit drives. Finally, check for proper waveforms at the anodes and cathodes. Since nothing lights, I would suspect a bad power supply or a construction error like swapping the pnp and npn transistors or backwards diodes.
I have mentioned this before, but the MM5314 does not have very good noise rejection on the clock reference input, so power line spikes tend to make it run fast. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
