1.怎样确定所修彩电为I~2C总线控制型彩电? 分有电路图和无电路图两种情况来确定。 (1)对于有电路图机,首先看主控芯片CPU某些引脚标注有无I~2C、IIC、I2C、ITT这些符号,有,一定是总线控制电视;没有也不一定不是总线控制,还要看CPU上有没有SDA、SCL数据与地址总线,若此总线只在CPU与贮存器之间进行数据交换,一般认为是非总线控制电视,必须在CPU与信号处理电路间有SDA与
1. How to determine the repair color TV I ~ 2C bus-controlled color TV? There are two ways to have the circuit diagram and no circuit to determine. (1) For the circuit diagram of the machine, first of all look at the master chip CPU pin marked some I ~ 2C, IIC, I2C, ITT these symbols, there must be bus control TV; no nor is not necessarily the bus control, but also Depends on the CPU there SDA, SCL data and address bus, if the bus only in the CPU and the exchange of data between the storage is generally considered non-bus control TV must be between the CPU and the signal processing circuit SDA and
