Hi, I have a 37" 9986 with Sky (Amstrad box), a really old DVD player and an even older VHS recorder. Most of the time the picture quality is excellent but under certain conditions when watching Sky I can see diagonal banding. This is most apparent when viewing a solid colour such as a blue sky scene (Discovery Wings) or when you get those splash screen that say ...Back Soon... or ...Don't Go Away... during programmes. I have not noticed the diagonal banding when watching DVDs. I swapped the scart leads over and the problem was still evident. A friend believes that the diagonal banding is caused by noise being introduced by the Sky box. I would be grateful for any thoughts or advice. Regards, Peter.
