Help Please!

I have a Dish installation with 2 receivers (1 VIP622 and 1 212K) with legacy equipment in Puerto Rico 2 3X4 Switches and 3 SW-21. The problem is that a couple of days ago I lost the HD channels (Signal Loss Message) comming from 110 SAT on transponders 18 and 20. Doing a troubleshooting I noticed that the signal in those transponders is very low (13-22) even though those tps are on spotbeams to PR. The other tps are ok (signal close to 100). What is going on here? I have played with the switches and lnb with no success.

I can't really help with why, I did just check here, 110 transponders 18 and 20 are right at their normal for me, 75 to 77.
