Lost TP 24 on 148°

[brada]

Is anyone having problems with Pentagon and ARTS channels on 148°?
Getting that 002 error...
I have two other PI channels from this sat, PAEC and "Holistic...", they look good.
When I go to Setup dish pointing screen, tp 24 even does not appear there.
Is it gone?
.................
Just want to add, that sky is perfectly clear, it's not a rain fade, and not a misaligned dish.

I have noticed that there is no signal from any even tp, like 4,6,..16 etc.
Also, I called customer support, and they asked to check if my both receivers do the same. I switched receivers and the both cannot see even tps. This made me think that my LNB is gone bad and not switching polarity.
I am wondering, if I switch to another port on this LNB, will it make a difference?
Also, it's a DishPro dual LNB, can I replace it with legacy dual LNB (the rest of the system is DishPro)?
