Exported File Won't Play on TV

This is my first time using Premier Pro, so I'm not that familiar with it. I created a video that has static images and a video overlayed on top of it. The static image is from photoshop with 3 layers. The background layer is on the bottom, video file on top, and then the other two static images above the video file. I exported the file using the standard setting shown in one of the learning videos, Format: H.264, Preset: Match Source-Medium Bitrate onto my desktop and it played perfectly. I saved it to a USB and plugged it into a Samsung UN50MU6070, but the file will not play. The file appears on the tv, but when I hit play, it won't play. I am trying to create a menu board with movement over a static image, can someone please help? Did I do something wrong?
