    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.

    Hi Sir:

    Please review very carefully, the Ribbon cables, or Flat cables, for open, or faulty, or corroded , clean pins, or edgen with eraser pencil
    They accumulate oxide. or pins bends, or corrodes in the case or ribbon cables. in both cases if are faulty replace it.

    Thank you.

    First at all you never must manipulate variant code (if you don't have knowledge) . Looks like Variant code was missing... But...achine cam running? General functions works? It is a 102s looks like achine close year 90. If you have icons that don't appear is probably an eak with failure or a conector in printing unit broken...
