I took the TV and Receiver out to the Tahoe and put it in the hatch back so I could SEE IT as I worked. Turned it on and pulled up the Setup menu.
From there select System Set Up and then View Satelite Strength.
You will get a screen full of numbers for the different transponders.
Start at about 190 degrees azimuth, and 54 degrees elevation.
As you rotate the dish continue to push the yellow Select button as it will refresh the transponder numbers.
Tiny moves, when you hit on a signal stop, wait for the rest of the transponders to show numbers.
Then make tiny adjustments for azimuth and elevation. Once you are showing 90-92+ on most transponders, you are there.
Directv has a satelite locator by zip code but it just didn't pan out for me. The manual way above took about 10 minutes from start to finish!
