In part, the previous user's answer concerning "service only" was correct. The port was designed for uploading new software to the TV for functionality. However, approximately 1 year ago, we changed our models to allow the playback of .mp3 and .jpg files. If you can provide the serial number of the TV, I will check with our engineering team to see if we can provide a firmware update for your television that would allow you to play these types of files through your television as a picture slideshow or music playback.
