Magnavox Television Set
Examine the composite audio and video cables that came bundled with your PS3. One end contains three plugs of three different colors -- red, yellow and white. The other end is rectangular.
Plug the rectangular shaped end of the cable into the "MULTI AV" input on the back of your PlayStation 3.
Plug the three colored plugs into the inputs of the same colors on the back of your Magnavox television set. The PlayStation 3 can now send audio and video information to the Magnavox television thanks to the audio and video cables.

Turn on the PS3.
Open the "Internet Connection Settings" menu option on the console. This option is located in the "Settings" menu under the "Network Settings" item.
