I am trying to repair the LED display on a jukebox. It is a typical 7 segment display unit with 6 units wired in series. The devices are a NTE 3079 (or equivalent). All segments except A and C (top and Bottom right) light on all six units. A & C are common, according to the diagram. I have replaced the driver, which is a NTE2018. If one of the units fail, will all of them do the same, since the wiring is series, as it appears?
Thank you in advance for any help.

If the LED's are in series, as you suggest, then, yes, if one of them fails, they will all fail (assuming they fail as an open which is likely).
