I just had an installer come on Friday to install a new dish and the samsung 7160 hd receiver. While he was there all the channels came in. Today, I cannot geta signal on the ESPNHD, HDNET Movies, HDDiscovery. I can only get HDNET and HBOHD. When I test for signal strength it shows no signal on the 110 satellite. I called the installer but I'm put on hold. What should I do? Should the 110 satellite have a signal?
