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

Contact the store, I know some stores have the demos locked so that people can't mess with them.

My TV had the same problem and I have managede to get rid of it. The solution is very simple. This displays mean that your TV is in the " Store Demo" mode and any changes you make will last only for 30 minutes and when the TV is turned off the settings will change back to the normal. Whether you TV is in the "Store Demo" mode can be confirmed by pressing the "Info" button on the remote and you will see that "store demo" appears on the screen. To change this mode to the "home mode" you will have to press the "Volume button" on the TV and when the volume sign appears on the screen then you will have to press the "Menu" button on the TV (not on the remote)and hold it down for about 7to 10 seconds. This changes your TV mode from "store demo" mode to the home mode. Confrim whether the store demo mode has been put off by pressing the "Info" button on the remote to see whether the store demo sign appears on the screen. The store demo is set by sales persons in the shops so that any demonstratation/changes that they make while showing to customers will be temporary as the settings revert back to the original.

Hi,
Since I do not have your tv model number so can't be specific, check Demo mode option in Menu and turn it off. Some tvs have selection like Store/ Display and Home mode, store or display mode is demo mode so set tv on home mode to turn off demo mode.
Let me know model number of your tv if you have additional question.
Thanks.
