How to disable store demo mode in Samsung LCDTV




What is Store Demo Mode or Shop Mode?

Essentially, Shop Mode or Store Demo Mode returns the TV automatically to its default settings in thirty minutes. It is usually used by retailers who want to demonstrate functions to customers, and then want the TV to return to its default settings without the bother of manually resetting the TV.

Easy FIX in removing your Samsung LCDTV from Shop Mode or Store Demo Mode. First, confirm your TV is in Shop Mode or Store Demo Mode:

1. Press the INFO button on your remote control. A list of settings appears.
2. See if the Picture Mode setting is set to Shop Mode or Store Demo Mode.

There are three methods for removing your TV from Shop Mode or Store Demo Mode. If the first method does not work, try the second or third method.

Method 1
  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.
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.
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.
