5. Not knowing what cables you have (always use the best you have) nor whether you are connecting directly to the satellite or to the service provider's set-top box (receiver) you would be better off repeating your steps.

7. Once you have determined whether you are connecting with HMDI cable (which carries both audio and video) to an HMDI jack, using a 3 cable component system with both audio and video or a composite video with a separate audio cable or a coaxial audio video (not the best choice with this TV)
8. Locate the corresponding jacks on the TV and on the receiver. You will see image of both jacks and cable ends on page 7/pdf 11
9. Next refer to page 8/pdf 12 of the manual to connect the TV and receiver.  Make sure they are not plugged in yet.
