Press the menu button on your remote--hit the up arrow three times - (there will be a gear looking icon) it will highlight plug and play -- press enter -- press the up arrow once - you should now be on Sw upgrade -- press info - firmware will be displayed on bottom of the screen.
Congrats on your set
