I`ve been interested in buying the 435 or 505 xde screen until I went for a demo in Eastbourne last week. Their 435 had the words (Recordable dv demo)burnt into the screen, obviously I`m now worried about buying a plasma. Can anyone tell me how easy is it to burn a screen and has any one had particular problems with the pioneers? Are the sky or ntl logos a real problem or can problems be easily avoided? What is the maximum time you could leave a static image on screen?
