Original Abstract Submitted
A display diagnostic system and method include a sensor configured to monitor a parameter of a light emitter of a display device. The light emitter is configured to emit light to illuminate a display screen of the display device. The light emitter is powered by an inverter of the display device. The system and method include one or more processors that receive a sensor signal generated by the sensor. The sensor signal is indicative of the parameter of the light emitter monitored by the sensor at a first time. The one or more processors are configured to determine that the light emitter is inactive at the first time based on the sensor signal, and, responsive to determining that the light emitter is expected to be active at the first time, generate a control signal indicating a fault state of the inverter.
