近几年,随着电子技术的发展,很多新型彩电都采用了I~2C总线控制系统。彩电应用了I~2C总线控制系统后,CPU和被控集成电路引脚大量减少,这不仅大大减少了整机电路元件,简化了电路,提高了产品可靠性,而且为增加CPU和被控电路功能创造了条件,给生产和维修带来了极大方便。采用I~2C总线控制系统的彩电在电路结构和校制方式上均不同于传统遥控彩电,其故障的现象和故障机理也与之不同,因此,维修时的判断分析思路、检修方法步骤也有所不同。
In recent years, with the development of electronic technology, many new color TVs have adopted I ~ 2C bus control system. After the application of I ~ 2C bus control system in color TV, the pins of CPU and controlled IC are greatly reduced, which not only greatly reduces the whole circuit components, simplifies the circuit and improves the product reliability, but also increases the CPU and the controlled circuit Function to create the conditions for the production and maintenance brought great convenience. Using I ~ 2C bus control system of color TV in the circuit structure and calibration methods are different from the traditional remote color TV, the failure of the phenomenon and the failure mechanism is also different, therefore, the maintenance of the judgment analysis, maintenance methods and steps different.
