    I don't have a Sony HCDX1, so if this doesn't work, please do not rate me down.

    Push the PLAY and STOP buttons (at the same time) and hold them for about ten seconds. This should get you out of DEMO mode.

    Power the unit off, then back on. If the display now says LOCKED, then press the PLAY and STOP buttons (at the same time) again to unlock.

    If this does work, please rate it Solved, so others can use this solution. Thanks!

    Lock and Demo Play Display

    while the demo is playing you must press "Play"and "Stop" buttons, then display shows DEMO OFF and you can now take the DEMO CD out.
    In some models you need to turn off the power and turn it on while pressing the EJECT Butoom.
