Considering that you have a DishPro receiver and a DishPro Twin LNB, your 3 foot test setup should reveal the following result:
Conn | Conn
X | X
DPTWin | DPTwin
It should only be doing a 2 step test: 1 of 2, 2 of 2
In any circumstance, the DP receiver you have should recognize the DP switch (LNB) that you have, regardless of whether you have a satellite signal or not. If the switch result is not identifying the LNB you have, then you have a bad receiver, bad cable, or bad LNB. Isolate the problem by swapping one part at a time. Try a different receiver, try a different cable, try a different DishPro LNB.
If it is doing a 38 step test or some other long series of tests, then you probably have a bad LNB or the receiver is bad. The 38 step tests are for older LNBs that are not DishPro.
If your result is
|x|x|x|x| then your receiver is doing a legacy switch test and is not communicating with the LNB.
