Yesterday the Dish Network folks installed a HD 811 receiver in my home that is connected to a Mitsubishi 65-711. The 811 unit is connect to the 65-711 HDTV via component video connectors (Y Pr Pb) and the 65-711 device input is configured to component video inputs. When the tech reconfigured the 811 video out signal from 480P to 1080I, the picture becamed scrambled. My over the air HD signal that I have connect to the set seperately works fine. Does anyone know if there is a problem with the Mitsubishi or 811 that would be causing this issue?
