I am only seeing very low voltages on the VFD wires (around 0.1Vdc).
I suspect that the VFD chip is dead. The signals on these wires are best observed with an oscilloscope, but most multimeters will read it as a voltage higher than what you are reporting.
We do not have the chips available for individual sale, but they are available direct from Maxim as well as from other suppliers. http://www.ladyada.net/make/icetube/parts.html
If you post photos of the front and back of the board we can check over the rest of your assembly too.
