    Hi :
    Normally when this happen,
    1) is status of lack of voltage to the servo motor, or connection loose, broken, or dirty or corroded,
    2) Pot dirty, or loose wires, or defective.
    3) Or servo motor defective, try to exchange with another that is working, a test it.

    Try turning ON with just One SSK board, try all the boards individually till you isolate the board with the problem.

    If the SSKs dont work individually and the red light still does not come ON the problem might be with your SAK board (or the cable in worst cases), no blinking red light means no communication to the SAK
