Loss of E4 picture/sound
 

Hey all, this is a wierd one as I can get 100% AOK picture on all channels bar E4...? Sometimes there will be a picture with no sound, or picture and sound, or picture and sound but the picture is freezing or breaking up.

My first guess was the SCART lead - so I changed it with a good new one but nope, still the same....I have looked at both the scart ports on the box and tv and they look at first glance to be fine.

it is obviously wierd as I am getting fine picture on all other channels bar E4?! does it broadcast differently..?

TIA
