Digit 5 on VFD not showing up (Ice Tube Clock)

by skatterbean on Thu Feb 25, 2010 4:33 am

Hi, been trying a couple of things to get digit VFD5 to light up on my VFD. I've resoldered, checked continuity. Everything checked out. I did the following continuity checks:

jumper pins to VFD wires (all check)
all VD driver socket pins (check)
all jumper socket pins (check)

I also checked continuity from the 6921 pin 20 (which I am to understand is VFD5) and I get continuity to a wire on the tube.

Anything else I need to check? Everything else checks out perfect, just this one digit isn't lighting up.

Thanks!

Jay

Digit 5 is pin 17, Digit 6 is pin 20, counting from the right.
