For the last year or so, I havent been able to watch 61.5 and 119 channels at the same time. Usually the reciever locks on to 61.5 and when i try to watch 119 channels it says "Signal is weak". Then I would just scroll(channel up/down) through the channels and it would suddenly lock on and work. After the last bin I did a factory reset, and now i can only find 61.5 channels. Even on the 119 transponders it locks only to 61.5 and some transponders its just 0% quality but 80% signal strength.
signal is just the connection of the reciever to the lnb. If u are having trouble going from one sat to the other, like nalin said, could be out of allignment, OR also can be u have the wrong lnb type selected.
Run each sat straight with no switch see if problem goes away
i.e. place a coupler instead of a Sat switch One Sat at a time Scan each Sat See if yo can get first sat Step and repeat to other satellite Come back with questions
