作为有线电视系统终端接收器的彩色电视机，它所显示的图像质量和发出的伴音效果，无疑是相当重要的。近年来，有相当多的家庭都用大屏幕彩电替换了９０ 年代初期以前生产的普通彩电。由于大屏幕彩电的电路结构较普通彩电复杂得多，尤其是很多新型电路的不断采用，这对一些已经比较熟悉普通彩电的有线电视技术人员，有时也感到束手无策。为此，本刊从本期开始开辟了“ Ｃ Ａ Ｔ Ｖ 系统用彩电专题系列讲座”，特约《国产大屏幕彩色电视机大全》套书（四册）的编写者王锡胜高级工程师就近年来推出的十几个牌号近百个型号的新型彩电，归纳成系列机芯，分１５ 讲就其功能特点、电路结构、信号流程等作一介绍，供读者参阅
As a color television receiver for CATV terminal receivers, it is undoubtedly of great importance the image quality and the accompanying sound effect. In recent years, quite a few families have replaced ordinary color TVs that were previously produced in the early 1990s with large-screen TVs. Due to the large-screen color TV circuit structure is much more complex than the average color TV, especially the continuous use of many new circuits, which for some already familiar with ordinary TV cable TV technicians, and sometimes feel helpless. To this end, this issue from the beginning of this issue has opened up a “C A T V system color TV Series Lecture Series,” special “domestic large-screen color TV Daquan,” a book (four volumes) written by senior engineer Wang Xisheng introduced in recent years A dozen brands nearly 100 models of new color TV, summarized into a series of movements, sub-15 on its features, circuit structure, signal flow, etc. for an introduction for readers to refer to
