How do I view photos, videos, and music from a USB flash drive?
Insert a USB flash drive into one of the USB connections on the TV while it is switched on. Press HOME and select MMP (MultiMediaPlayer) from the Apps list and press OK. Use Navigation keys to select the file type (Video, Photo, or Music), then select the file you want to play and press OK. To safely remove the USB flash drive, press HOME, select the Notifications icon, select your flash drive and press OK, then select Eject and press OK.
