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.
