长虹公司继1994年推出“红太阳一族”NC-2、NC-3机芯系列彩电之后,于1995年又推出了“红太阳一族”TDA机芯系列彩电。TDA机芯是荷兰飞利浦公司于1995年研制开发成功的以集成电路TDA8361/TDA8362为核心的彩电机芯。该机芯采用单片结构,具有结构简单、紧凑,元器件少,可靠性高,售价低等优点。目前,采用此机芯生产的彩电有C2191、C2192、C2591、C2592、C2991、C2992等机型。 TDA机芯是长虹公司彩电今后发展的主导机芯,为了使读者了解该机芯的工作原理、电路细节,特发表本文,详解TDA机芯系列彩电中具有代表性的C2991/C2591大屏幕彩电的工作原理和有关维修技术。
Following the introduction of the “Red Sun clan” NC-2 and NC-3 movement series color TV series in 1994, Changhong Company launched the “Red Sun clan” series "TDA movement series color TV sets in 1995. TDA movement is the Netherlands Philips developed in 1995 to the integrated circuit TDA8361 / TDA8362 as the core color TV movement. The movement of the single-chip structure, with a simple structure, compact, less components, high reliability, low prices and other advantages. At present, the use of this movement to produce color TV C2191, C2192, C2591, C2592, C2991, C2992 and other models. TDA movement is the main movement of Changhong’s color TV in the future development, in order to make the reader understand the working principle of the movement, the circuit details, especially published in this article, detailed TDA movement series color TV in the representative C2991 / C2591 large screen color TV Working principle and related maintenance techniques.
