    I have exactly the same problem

I would be interested if this solved it for you.

    I have exactly the same problem, and my Boom is well out of warranty. Did anyone discover how to make the now dead unit alive?

    Any news around here from a hardware freak?

    I've started to disassemble the device and tried to make some measurements. I feel like the power section on the board feeds the VFD with over 50 V! I guess, the VFD will be damaged anyway. But how comes that such high voltage is there?? Hope that someone's out there who has got some hints or schematic. Or a developer who wants to private mail me?

    Anywhere a chinese shoppe that sells boards as spare part?

    You should keep in mind that a VFD is a tube. Anode voltage can be 50 Volt.

    I made several layouts with several noritake VFDs, there was no one which needed more than 5V input.
