Abstract： With the development of economy and the progress of society， people's material living standard has been improved to a great extent. Moreover， the progress of science and technology has brought a lot of convenience to our life. According to the investi
gation and research， as far as the current image display field is concerned， some CRT display devices or plasma display devices have gradually withdrawn from people's lives， and liquid crystal display devices are gradually replacing them. But along with it， the first generation of LCD color TVs using CCFL backlight devices have many problems at present. Therefore， this paper analyzes the fault and maintenance of LCD TV black screen， and compares the similarities and differences in the working principle of CRT and LCD color TV， in order to put forward the fault analysis method and effective maintenance idea of CCFL backlight LCD color TV.生态系统理论
