Set your PC's output resolution so it matches a resolution supported by the TV.
If you are using an HDMI connection, check the audio output setting on your PC.
If you are using an HDMI-to-DVI cable, a separate audio cable is required.
Confirm your wireless modem/router is on and connected to the Internet.
Check the network connection status ((MENU/123)
Network Status).
If the TV is not connected to a network, connect to a network.
The upgrade stops if you already have the latest software version.
