Hi gang. Within the last week, I have suddenly lost most of my HD channels(I still have my locals - Minneapolis - ESPN, ESPN2, TNT, HDNET, DHT, HBO). All of the HD channels have always came in fine until last week. From the limited knowledge I have, I believe that the missing channels are on the 103 bird. I am getting the searching for satellite signal (771) error. Here is what I have checked and done so far. 1) View signal strength - 103(a) and 103(b) show up as 0 on all available transponders 2) Dish still appears to be pointed correctly on roof and nothing new appears to be obstructing view. 3) I have reset the receiver several times and have gone through the satellite setup several times. 4) Verified b-band converter in place. Any suggestions? I have a h20-600 which I am thoroughly getting sick of (reboots once to twice a day now). Is it possible this is part of the problem? Is it possible that the b-band converter is hosed? Any help would be greatly appreciated. I am really trying to avoid having to setup a D* house-call.
