I would be pretty sure that most of your displays are Ok.. If you have the lines glowing and they are straight lines and not pulsating when you added your 9 volts to the two outer pins then there probably Ok.   I would seriusly doubt that all displays would be faulty.. These FUTABA displays far outweighed the Bally/Stern displays of the same era for longgeviti...

Thanks Dean,

Initially when I was not getting anything, I thought it may be displays....Faulty alligator clip later and that side sorted.  Still no displays at all.
