    Reseated the thin ribbon cables, (J401 and J402 on the MCU pwb), between the MCU and IOT Driver PWB's.
    Clean each end gently with a pencil eraser and film remover and then reinstall.

        Perform a "Forced NVM Initialization"

        Power off machine.
        Turn on machine while holding down the following buttons on the UI.
        Power Saver button
        Stop button
        3 button
        Continue holding these buttons until the Interrupt LED starts flashing and then release.
