Red shadows on you LCD television can be a major annoyance that will hinder your enjoyment of the TV viewing experience. This problem can be alleviated with an adjustment to the convergence settings in the "Image" menu. The picture on an LCD television is created when three primary colors -- red, green and blue -- come together (converge) to create the image. If one of those color settings is off, a red shadow will appear on the TV, distorting the image.
Turn your television off. Wait 30 to 60 seconds. Turn the television back on. This quick fix method may work sometimes, saving you from more involved steps. If it does not alleviate the problem, move on to Step 2.
