Receiver is evidently seeing the lnb, but the lnb is not seeing a satellite.
Are you setting it up with a signal meter or are you using the receiver itself to peak the dish?
You need a couple of aluminum soda cans with the top cut off (or a good supply of aluminim foil) to cover the 110 and 129 lnb's on the 1000.2 so you can more easily find lock in on 119 with the center lnb.
Set the skew of the 1000.2 as per the table in the directions for the zip code where you set up the dish, cover the two outer lnbs, set the pole to absolutely vertical and be sure it is stable and solid there (if it moves you have spoiled the setup - REBOOT).
Place the dish/lnb unit on the pole (if not already there) and approximate the azimuth and elevation from the same table you go the skew. After a little tweaking you should find signal on the 119 lnb. Sweep the dish horizonally to find the strongest signal, then vertically to again find the strongest signal on 119. The receiver should now be able to lock the 119 satellite.
Last of all we tweak the azimuth, elevation and maybe skew, but it is usually OK, as in the previous step, to balance the signal strengths of 110, 119 and 129 (you may remove the aluminum cans). Sometimes you must sacrifice a good strong signal on 119 in order to bring 129 and /or 110 up to acceptable levels.
After all satellites are balanced you may run checkswitch to have the receiver save the satellite info in it's database (that's all check switch really is).
