From the information given, here are a couple of guesses. First, you will probably need a 211 receiver, the 722 is for 2 tv's and a Kingdome of that vintage will probably not communicate well with the 722, although it may work enough for testing. Did you download the directions for that model of Kingdome at the King Controls site. You should be able to hookup the cable from the controller box you see, to the sat in on the receiver, turn receiver on, and then force a search by turning the control box on, and forcing a search. Some do not automatically search on starting. also, one of that vintage may not automatically find the correct sat as you change channels on the receiver. You may have to change it manually upon choosing a new channel. After you have located 119, read the direction manual for that model of dome and check switch. The manual will tell you which switch you should see after checking. It should locate 110, 119 and 129 and will show HD if you have the HD receiver and TV. Hope this may help. Gives you some ideas to start with anyway. Good Luck Bert
