All Samsung TV’s come with a Shop Mode or Store Demo function. Designed for retailers who need a way to reset demo TVs to their factory settings automatically, these functions return a TV to its factory settings every 20 minutes or after the TV is powered off.
If your TV does not retain your settings, most likely it is in Shop Mode or Store Demo Mode.
To turn off Shop Mode, follow these steps:
1. Press the Vol + button on your TV.
2. While your TV screen displays the volume level, immediately press and hold the MENU button on the TV for seven seconds.
3. The word Dynamic appears in the middle of the screen momentarily.
4. Your TV should no longer be in Shop Mode. If your TV continues to return to the default mode, please make a service request at http://www.samsung.com/us/support/o...
