    Hello Gentlemen,
    I have a problem with a working SM 74-5P. The icons to enable wash-up for Unit 2 on the CPtronic display has disappeared whiles all other units remains as shown in this picture.
    What could be the cause of this fault?
    Is It software related or an electrical fault?
    Your ideas are welcome please.

    Hi sir:
    Please open the door of cpc or cptronic, and depend of the system that you

    have would be Old technology using 7 segments display common cathode or Anode see the attached schematic, can be faulty or burn. Replace or test it.

    Blessing.
