Abstract
A method of reprogramming a flash memory of a liquid crystal display (LCD) in a presentation device can include using an external electronic diagnostic tool and a controller area network (CAN) diagnostic interface within the device to initiate data transfer. Data can be transmitted to an LCD microcontroller within the device using a high speed infrared link between the diagnostic tool and microcontroller. The data can be stored in a memory within the device in bi-directional communication with the microcontroller. Proper reception by the microcontroller of the infrared transmitted data can be verified by the diagnostic tool and the CAN diagnostic interface. A command can be issued from the diagnostic tool directing how to employ the data to reprogram the LCD.
