[sdiy] Xpander repair help

[Scott Juskiw]

I have an Obie Xpander with two flakey displays. I've got the service 
manual, I've got a scope. All signals going to the displays are fine. 
It looks like there's an intermittent connection inside the display 
itself. If I point a heat gun at certain pins the display will work 
perfectly. But as soon as it cools, it stops working. I'm a bit stuck 
trying to figure out how to fix this. Is it possible to get 
replacement displays? I know VFDs are still being manufactured, but 
are there any drop in replacements? I couldn't find any.
