It sounds as if your television is in Shop Mode.

To disable shop mode, you need to do one of the following:

1. Hold down the menu button on the television's bezel (not the remote) for about 10 seconds.


2. Push the volume button up on the front/side of the television, release it, and then push down and hold the menu button for 10 seconds.

This should take out you of Shop Mode and effective leave your setting as you prefer.

Keep me posted.
