Methods and systems are provided for a transportation vehicle. One method includes determining whether a connector receiver module is electrically connected to a connector of a media output device during a maintenance mode, measuring a load parameter at the connector receiver module in response to determining that the connector receiver module is electrically connected to the connector, the load parameter being associated with an electrical load at the connector receiver module, determining whether the load parameter is below a load threshold, and reporting a maintenance indicator indicating a location of the media playback device, the maintenance indicator being based on at least one of determining that the connector receiver module is electrically connected to the connector or determining that the load parameter is below the load threshold.

Methods and systems for monitoring for faulty connector receiver modules of media playback devices in a transportation vehicle

Methods and systems are provided for a transportation vehicle. One method includes determining ambient light baseline for the flight by measuring a first light intensity by a plurality of light sensors located within a plurality of physical zones of an aircraft cabin, before a flight and transforming the measured first light intensity based on sensor locations within each physical zone of the aircraft cabin; adjusting brightness level of seat display device at passenger seats located in the aircraft cabin based on the ambient light baseline; continuing to measure in-flight light intensity by the plurality of sensors; and automatically adjusting the brightness level of one or more seat display devices in response to the in-flight light intensity varying from the ambient light baseline by a first threshold value.
