Turn off your LG TV and DirecTV receiver before you make any connections to the input panel.
The inputs on your LG TV are designed to handle a connection with your satellite TV service. Getting DirecTV service to display through your LG TV's inputs is as straightforward as connecting the satellite receiver to the input panel on the television set. Use an HDMI cable to display the best possible image and audio on your TV screen.
Insert one end of the HDMI cable into the "HDMI" port on the rear panel of the receiver.
Plug the other end of the HDMI cable into the "HDMI IN" port on the back of the LG TV.
Turn on the DirecTV receiver and the LG TV. Press the "Input" button on the LG TV's control panel until the image from the DirecTV appears on the LG screen.
