Unconfigure a source
If you have connected and configured a
source to a specific socket on the television
and then disconnect the source permanently,
you must reset the source settings. Select
the source from the SOURCE LIST SETUP
menu and select RESET TO DEFAULT. When
you select YES, the source is no longer
configured to this socket. Next time you
connect a source to the socket, you are
asked to configure the source.
You can also select RESET TO DEFAULT in the
ADVANCED SETTINGS menu to reset to
default values only in this menu.
To remove the downloaded PUC table,
see page 37.
