After all that, the VFD doesn't seem to work. It turns on, the fan comes on, the display comes on and I can even adjust the frequency using the little dial but none of the buttons work. Nothing happens when I press any of them.
excuse me one sec.... ARGHHHHHHHHHHHHHHHH..... m***** f*****s.... ok that's better.
I guess that VFD has a date with my trash can.
