Sony is aware that not all USB storage devices are compatible with our TVs. If you are using a USB device for playback of photos, music, or videos on your TV, the same USB device type should work for the update. If the software update does not automatically begin when you connect the USB device to the TV, you may need to format your device to the FAT32 file system, or use a different device.
