Hello Kat
I will do this to verify weather the LNB is defective OR not.
By the way
The two Fortecs R of different model
The Old is 786NA
and the new is Lifetime.
It seems to me that your dignosis is perfect due to my verificatio with the two receivers together.

Regarding the setting I was using the factory setting.Also when I connect the new receiver to the OLD dish (preset) it works out nicely
It is semi clear the defect is in the LNB.

Is it possible to get a defective brand new LNB !!
My experience in this field is not so dense as you but so far no similar case for me
