satellite tv dish

My dish of Greek satellite TV has no reception!?
Suddenly, my satellite TV is to have no signal at all. . . I have this dish for my Greek channels and also has plenty of other channels "religious" worldwide. Does anyone know what this is? I live in Melbourne.
You may have to disconnect your satellite box 5 minutes to turn the box so you can reboot … Or you may have a problem with the dish outside or cables, but if so, you could see the satellite "Finding signals" appear on the TV ….. Another possibility is that accidentally selected a video input device totally different in the satellite TV is not connected. So do not even see Guide Satellite / channel menu or numbers appear on your TV …. If you see information about the satellite video will appear on your TV then you know the correct video input, and satellite TV is working, and the only bad thing is either the satellite receiver or outside of the dish, or cable from the dish and the dish …. Receiver Divide and conquer your problem ….
