LCD which means Liquid Crystal Display has become popular as a technology in TV sets today. The basic principle on which this works is that liquid crystal is placed between two sheets of clear material and is back lit to display an image. This is not the same as a plasma screen TV that works by lighting up small plasma cells filled with neon-xenon gas. Although LCD TVs are known for their sharp and clear displays, like every electrical gadget, they too can occasionally run into problems. These could vary from colored lines appearing on the screen to internal component failures that lead to the TV not coming on at all.
