I am viewing 119 only, using DP301 and dual legacy lnb. I have lost the signal completely. I am sure that it is not a receiver problem because it works on another dish, lnb, and associated cables, but otherwise I don't know what the problem is. I have a spare LNB that, in principle, I could swap out and see if it is the LNB. But this is difficult to do, given the dish location. My question, then, is whether I can get an idea if the current LNB is OK from inside the house by measuring voltage or something. I have a volt meter, but otherwise no special instruments. TIA.
test LNB from inside house?

Pretty much all you can do is run a switch test from inside. More than likely you will need to have the LNB replaced. Call a local retailer to see what they will charge to replace it.
I am already on the wait list for the local satellite techs, but they are hopelessly backed up with work because of a recent rain and wind storm. The only thing that I can do is wait or swap out the LNB, if I suspect it is shot. I realize, of course, that the most likely problem is dish misalignment. I can use the receiver to change transponders (apparently). Does this mean anything re the LNB?
Well... With legacy LNBs, you can't tell much because communication is one-way. Your receiver sends it either 13V for odd transponders and 19V for even transponders, and the LNB just blindly sends down the whole block of even or odd transponders. If the dish is misaligned, or the LNB fell off and came crashing to the ground and broke into a million pieces, you would have no way of knowing from the receiver.
DishPro LNBs are better in this regard because communication is two-way. The receiver can at least tell it's connected to an LNB, even if it can't know what satellite (if any) it's pointed at until it gets a lock.
