Many Sony televisions have the option of setting the TV in either home or demo mode. Some sets call demo mode "retail mode" instead. While in demo mode, the TV will display a demonstration of its features. Demo mode is mainly there for retailers who may use the set for demonstration purposes or as a floor model. You can turn off demo mode by resetting the TV and choosing the proper mode using the remote.
