After a few days, without any reason, one frequency channels start showing me error 101. however, when I rescan the channels they start working which proves this is not a signals issue. It's like Dish TV forget the frequency. In my case, i am facing this issue on a frequency which is having Zing and Movies Now channel. I am 100% sure about the signals because the same channels are having full signals on FTA set top box and Dish TV NXT box connected to same LNB in the 2nd room. Anyone facing such a fault?
