Guessing. Unplug power. Hold power button pressed on, then plug in unit. Take careful note of any lights and their sequence.

That's "blind guesswork."

SOURCE: How to turn off this blasted DEMO mode on MP235

Once in standby you have to press and hold the button to get into the menu. Once in the menu, you use the joystick control on the right to navigate to "Demo" and toggle it to "off" (can't remember off the top of my head... you either have to press the joystick in and hold it to toggle or just move it up/down...). Once done, just press Source to exit.

SOURCE: Stuck in demo mode

When you are in STANDBY mode hold the menu button for a few seconds and a special menu should pop up. In this menu you should be able to set the clock, turn off or on the beep, and take your unit out of demo mode. Good luck.

If this cd player has a removal fascia then try..

Carefully inspect the the electrical contacts on the fasica and the cd player. If it has got dirt on them then CAREFULLY CAREFULLY clean with cotton swab dabbed in cleaning Alcohol.

SOURCE: stuck in demo

I had the same issue and was about to give up.
cleaning, key combos and such didn't work out.

Solved the dirty way, as described some comments above:

"Just took the faceplate from the "push-menu" button and hit it against a hard surface [not too hard but not too soft hits] and thats it, it worked again."

ah, the good manners!

Can't get out of demo mode


On most, if not all similarly styled refrigerators, demo mode is toggled off and on by holding a combination of buttons on opposite sides of the display. Which buttons can depend on manufacturer, model, and display or button layout. For most LG refrigerators, it should be the "Refrigerator" and "Ice +" buttons. Hold them until they sound a beep to indicate a change in the demo mode status. It should not take more than 10 - 30 seconds.

If that does not work, and there are other buttons on opposite sides of the display, then try the other opposite pair of buttons.

Aiwa CDC-x204 stuck in demo mode


This is what worked for me:
  1. Power the radio off (hold the power button in top left corner in for several seconds)
  2. Remove face plate
  3. Hold in reset 10 seconds
  4. Press push-menu dial/button 3 or 4 times
  5. Insert cd and hit source to switch to tuner before cd starts
Not all of these steps may be necessary.
I suspect having the power off before the reset button was the important part.
