For about a month I have been having an issue with one of two Hoppers not being able to find satellite signals. I can be watching tv with all channels available. When I go to change channels, an error message comes up that "Satellite signal has been lost." Try to switch back to the channel I was on and it shows the same message. After a reset, the Point Dish procedure will only find one or two satellites. For instance, tuner 1 only finds 119, tuner 2 only finds 119, and tuner 3 only finds 110. Or sometimes all three tuners find 129, or one of the others, but not all three. The first tech that came out changed out the LNB on the dish. That worked for about 4 hours before the issue came up again. The second tech came and changed out the duo node on the outside of the house. Again, after a few hours the same problem came back again. Then this week, they changed out one Hopper that was having the most issues. Still having the satellite signal issue. And now, both Hoppers have the same problem. The last tech said if changing the Hopper didn't work they would have to send out a master tech to find the problem. It has been two days and I have not heard anything.
