if you are using a diseq switch replace it.switches are known for giving problems.also check all connections, also check your settings in antenna setup.
I have a 18inch Dish and I am trying to get both 110 & 119 using two LNBs ... as soon as I attached another LNB ... my signal level went down on 110 !!! ... Any idea why ?! ... Do I need a big dish ?!
U just need to align the dish with 2 LNB's correctly, have a working disque switch, good cables and connections...
then input the corresponding antenna settings, scans the satellites, set the date and time, reboot the receiver, upload the latest fix, let the keys roll in..and watch TV..
