Quoting from manual above (may be similar model if not the same.)

7. Turn on or turn off the display demo mode.
The console features a display demo mode,
designed to be used if the treadmill is displayed
in a store. While the demo mode is turned on, the
console will function normally when you plug in
the power cord, press the power switch into the
reset position, and insert the key into the console.
However, when you remove the key, the screen will
show a demo presentation.
To turn on or turn off the display demo mode, first
touch the Demo Mode button. Next, touch the On
checkbox or the Off checkbox.

The following is from your Users Manual:

Demo Mode IMPORTANT: This feature is intended for use on the sales floor with 120 V power connection and permits the control features to be demonstrated without heating elements or burners turning on. If this feature is activated, the oven will not work.
1. Press OPTIONS until "DEMO MODE" is displayed.
2. The current setting will be displayed.
3. Press the "1" keypad to adjust the setting.
4. Press START to save the setting.
5. Press OFF to exit and display the time of day http://www.kitchenaid.com/digitalassets/KERS306BSS/Use%20and%20Care_EN.pdf

I have same problem mine was a store demo. I just got off chat with samsungs website. In order to get out of demo mode you will need model, serial, and remote, mine did not come with a remote so im out of luck so far. Try going to samsungs website and chat they were very helpful.. Hope this helps!!!!

Your TV appears to be in what is known as DEMO MODE, which is used when the TV is set up in the store on display.

In order to disable that mode and return it to normal operation, try the following procedure:

Turn on your TV.
Hold down the VOLUME UP and the VOLUME DOWN buttons at the same time for 10 seconds.
Be sure to use the buttons on the front of the TV and not the ones on the remote control.

Some models may turn off at this point while others may not. Either way, the set should now be ready for use in NORMAL MODE.

If that does not cure the problem, then check in your OWNER'S MNAUAL for the exact procedure on how to disable the demo mode feature.

I hope that was helpful to you, good luck and take care.

Okay. I found that there IS a manual release for the disc tray UNDERNEATH the unit. It is a sort of toggle lever that you have to slide to the other side and that releases the disc. The Manual does not even mention this manual release lever!

Also, it may be hidden or covered by a paper like cover.

Pressing "timer/clock" button 4 times turns on and off demo mode.

I just bought a condo with a GE Spacemaker Mod# JVM1860SD
that was stuck in demo mode. (This mod# has been replaced by the JVM1870*** series)

I called GE twice in two days, and finally got someone who had the solution (and it worked):

1. Unplug the unit for at least 30 seconds
2. Plug the unit back in DO NOT SET THE CLOCK
3. While the unit is still "booting up" and the display screen is lit with gibberish, HOLD THE POWER LEVEL AND THE ZERO BUTTON for at least 5 seconds.
4. After 5 seconds, the screen will display "demo mode off"

It messed me up at first because the power level and zero pads don't beep when the unit is booting up... but it worked.
- Again, this is for the GE Spacemaker 1860-1870 series models only - The women who gave me instructions said she had different demo mode unlock methods for the 1400, 3670, 2070 etc... so call GE if you have a different model.
P.S. my model looks like this - the keypad setup is key http://products.geappliances.com/ApplProducts/Dispatcher?REQUEST=SPECPAGE&SKU=JVM1870SK&SITEID=GEA
