Aiwa CDC-X504Mp stuck in demo mode

I also have exactly the same problem with the player stuck in demo mode. I can only get into setting mode of the clock. Otherwise none of the buttons work. I have tried putting the player in DEMO OFF mode by holding PUSH/MENU, but I can't access the set mode. Can any one help?

This recently happened to my Sony, maybe it will help u

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.

I have seen this many times on my 2 stereos. Sometimes it can be fixed by these methods

1) Just keep punching buttons at ramdom on the faceplate and eventually it may unlock. This is about all you can do if you are driving at the time.

2) Take off the faceplate and hit the stereo reset button with a toothpick or paperclip. This button is under a small hole on the front of the stereo behind the faceplate. Hold the reset down several seconds. This will lose all your station presets etc, but sometimes will unfreeze the faceplate when you put it back on.

3) Totally remove power to the stereo by pulling the fuse, or taking the terminal off the car battery. This is very inconvienient, but does a fuller reset than just pressing the reset button.

4) If all else fails (and it has for me once), go on Ebay, and search for "CDC-X504MP" and buy a replacement faceplate.

I had the same problem. and after many attempts i found the way to unlock demo mode. put your player into setting mode of the clock by pressing DISP button for at least two seconds. and then pres SOURCE button.. this helped in my case.. i hope this is the same for other players.. as easy as it sounds.. :)

Here's how I fixed this problem with the receiver locking in Demo Mode.

With the face on the radio and power on, I quickly pressed the "Push - Menu" knob repeatedly and firmly for a few seconds. This worked for me after trying everything else I've seen in the forums.

Good Luck!

Hi Folks, I have an Aiwa CDC x204 car stereo that seems to be stuck in demo mode. I replaced the battery, so my guess is that this is the default. Upon reading the instructions, it indicates to...

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.

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!
