I recently bought a Philips 24inch Widescreen tv to go with my Sony DVD player. however, i have experienced problems with my tv picture. The problem is several shadowy vertical lines are visible on my screen which are a lot more noticeable when watching movies with dark backgrounds. I have had this problem with all of my previous tv's but i associated these lines with bad reception (I live in a poor reception area) However, i only use my new tv to watch dvds so there isn't even an arial connected. The only connection is a Scart to Scart rgb lead. These lines can be distracting (although they are not very noticeable in bright scenes in movies) Could someone please suggest what these lines could be?
