I have a dish 500 and recently noticed that I am missing the science channel which comes in on the 110 satellite. When I do a check switch, only the 119 shows up. Swapped inputs on the SW21 switch and the 119 follows but still no 110 (shows XX). Installed a new LNBF for the 110 and still nothing. Tried new cable from LNBF to switch and nothing. Is it possible to have such a good signal on the 119 and nothing on the 110? Should I try to re-align? Thanks!
