Don't know if any of you knowledgable folks can help me out here ? When watching TV I can see rolling diagonal lines accross the screen . If I switch on the Video player they go away for a short time but then return. Similarly if I switch it off again they disappear temporarily. I have got other kit attached to the TV too - Denon 3300 amp, DVD player, all via scart (Panasonic PF10 has 3 rear scarts) Any ideas, or do you need more info ? Many thanks, Simon.
