How do I perform Plug and Play Reset?
Plug and Play allows you to play contents on your television from your external device without the necessity of prior installation with your television. Please note current models do not have Plug and Play option selectable from Menu but content can be played by selecting the media files. For other models, access Plug and Play using your remote control and select Menu > Setup > Plug & Play. If you are not on the TV source the option Setup will be greyed out.
You can reset all of the settings back to the default settings. Click on the link to know how to factory reset your television.
