Your not helping us to help you. You havent supplied enough info - Im working on guesswork here. Now just exactly what are you trying to watch?? And what is this about the image - - "image" can mean different things on different receivers - on linux boxes it can means the software loaded..
If you are talking about the picture / video output say so - and if you have lost the picture since the receiver has started making clicking things then its faulty. (Possibly a switched mode power supply)
Or the video circuitry could have gone bang of course.
