I was recently on a Dish Network service call and the 322 receiver was fried in a storm. When I replaced it with a new receiver I was able to see a strong signal on the signal meter but the check switch would not complete. I got 1 of 3 on 1 tuner and 1 of 38 on the other tuner. I tried both TV1 and TV2 (yes, I switched the diplexer too) and got the same results. The only thing I did not do is rerun the cable (I'm doing this tomorrow because it's a wall fish job) but if that doesn't solve it, what could it be?
