There is a setting in the TV menu called Plug and Play...that's where you set your TV set to Home Mode instead of Shop or Store mode. You are presently in Store mode, because it's bringing up various displays of it's features.
Look on the front right side for the buttons, as your may be a touch keypad, instead of the pushbuttons. Look for the MENU button, and press it.
Now the Channel buttons move the box up and down, while the Volume buttons move it left and right while the enter button is located on the front too.
Select the Home mode in your menu.
If you have any questions, just ask
If you are finished, please press the ACCEPT button.
Tips are greatly appreciated !
