I just found a solution elsewhere on this site...
In order to make the Demo Mode stop, you should press Volume Up and Channel Up together, and hold for four seconds. This worked for my mom's tv, I hope it works for you, mooone (and everyone else, too).

How to emove the demo on screen ?


Removing Your TV from Shop Mode or Store Demo Mode

First, confirm your TV is in Shop Mode or Store Demo Mode:

Method 1

To remove your TV from Shop Mode or Store Demo Mode, follow these steps:

1. Press the Volume button on the side panel of your TV. If your TV does not have a side panel, press the Volume button on the front panel. The TV displays the volume bar.
2. Press the Menu button on the side panel of your TV for about seven seconds. Again, if your TV does not have a side panel, press the Menu button on the front panel. If Dynamic or Dynamic Mode is displayed on the screen, your TV has been removed from Shop Mode or Store Demo Mode.

Note: You may want to press the INFO button on your remote again to confirm you TV is no longer in Shop Mode or Store Demo Mode.

Method 2

1. Press the Volume button on your remote. The TV displays the volume bar.
2. Press the Menu button on the side panel of your TV for about seven seconds. Again, if your TV does not have a side panel, press the Menu button on the front panel. If Dynamic or Dynamic Mode is displayed on the screen, your TV has been removed from Shop Mode or Store Demo Mode.

Note: You may want to press the INFO button on your remote again to confirm you TV is no longer in Shop Mode or Store Demo Mode.

Method 3

1. Press and hold the Volume button on your TV. The TV displays the volume bar.
2. As you are holding the Volume button, press the Menu button on the side panel of your TV for about seven seconds. Again, if your TV does not have a side panel, press the Menu button on the front panel. If Dynamic or Dynamic Mode is displayed on the screen, your TV has been removed from Shop Mode or Store Demo Mode.

Note: You may want to press the INFO button on your remote again to confirm you TV is no longer in Shop Mode or Store Demo Mode.

The tv has been accidentally set for "demo mode". Press the volume up and volume down buttons in front of the TV at the same time for about 5 to 10 seconds untill the demo disappears or sometimes the TV will turn off. You should regain control of the TV after this.

Pre-set message in a continuous loop on tv. Can not get it to stop. Maganavox Model No.: 25TRC10101


Try holding the channel up and volume down buttons together on the front of the set until the set turns off. When you turn it back on it should be normal. If channel up and volume down doesn't work try channel down and volume up. One of the two should do it. This demo mode was for in store demonstration. Thanks
