Greetings!

Actually, I am out of spares that I had planned to sell at the moment. I wanted to keep three spares for my own units, but in the end I had to sell one of those (I had already committed to the person, but I had not heard in a while and released the VFDs to others).

I will hold on to these spares for emergencies / breakages down the road. I will also check to see if Noritake has any lying around in stock still. If I find more in stock, I will post.

Meanwhile, the problem that you had is not unheard of. Basically, it is a fault in the VFD itself. There have been a few like that in the past. The only remedy is to replace the VFD, as you have already found out.
