...is the old big screen.? Does anyone know where the monitor/TV function is on a Mitsubishi 5072 TV? It is the old big screen. The sound still works and we can see all of the menu screens, but there is no picture and it was saying "Tuner Out". From the advice we have found on-line, people say that we need to switch the TV from Monitor to TV. But, we cannot seem to find what menu to do this from. Thank you in advance.
