I have two satellite dish ( one for 119 and one for 110 ) Both work if I hook it staright to Individual receiver. I can not pick up both 119 & 110 using the swithces. I have tried a total of 6 switches ( tried all combantion between LNBs 1,2,3,&4 ) IT does not work

) But if I hook it straight from the ********** it works.
Can anyone please help.
