+To obtain complete list of available sources currently configured on the TV, once the webOS TV is configured and linked, while its powered on head to the **Developer Tools** > **States**, find your `media_player.<name>` and use the sources listed in `source_list:` remembering to split them per line into your `sources:` configuration. If you leave the `sources:` configuration empty, the `media_player` will offer all sources of the TV. If you list a subset of sources in the configuration, only those will be displayed.

+Note: it is normal and expected behavior that for a switched-off TV only the Live TV source is offered in the `media_player`, even if you have configured other sources as well. These will show up as soon as the TV is switched on.
