I recently became a DTV customer fo rthe first time 3 months ago. Prior to that I had never been a satellite customer of any kind. I've always had cable. Tonight when I got home form work my wife told me the satellite was doing weird things... All my DTV sat channels are freezing, pixelating and losing signal. The signal strengths for the 3 transponders register 93,89,87. My OTA HD works fine. I called DTV and they say it's probably the lnbs or multi-switch or the receiver itself. I have a Sony Sat-HD200 receiver. Does anyone have a clue on where I should focus my attention?
