I have a two week old Sony lcd rear projection and it has one green pixel and a few black pixels. The black one look smaller than the green one. also there is a vertical row of about three that look darker than the rest which shows up as a line on light backgrounds. The shop has an engineer coming out on Saturday to check it and confirm if its duff or not but I was told by the shop LCD screens dont suffer from dead pixels very often. I dont want to get a replacement and find I get even more on the next one. any advise or would a plasma screen be better replacement?
