I have a relatively new R15-100 that I had installed with a new Dish (old one was a single lnb Sony dish installed 10 years ago!). I had an issue where I had tried to order PPV and the website would not let me - something about my access card. When I called D*, the CSR told me that the issue was that it was not hooked up to a phone line - therefore, the website will not allow the order. It was/and is hooked up via a RCA wireless unit. While I was on the phone with the CSR, I went to the info/test part of setup and ran the test. Everything was ok, except the LNB Output Test - which failed. (the phone failed too, but I was on it and the CSR could hear that it was trying to connect - I have also since verified that it works via the test). She did not seem to know what this meant, but I am concerned that something is not right. Both Tuners seem to work and for the most part the unit has been solid. I did have one experience last night with MNF, where the screen went black while watching. I had to turn it off and on, and then it seemed to work for a little while - did it again, and I did a reset using the remote. This also worked, and it seems to be ok. However, I am still concerned about the LNB Output test failing. Is there something I can check? The entire setup from Dish, cabling, and receiver are all brand new - so what might the issue be? Should I call this in to D* to have them look at it?
