海信TG-1B系列彩电采用东芝单片小信号处理电路TB1227N,由于控制系统软件不同,分两种电路,两种电路存储电台的数量不同,总线系统的调整方法和调整项目也不同,但两种电路的总线系统基本相同。微处理器N A01(M37222M6-084SP)有3组总线输出:第一组NA01通过38脚的数据线(SDA1)和37?
Hisense TG-1B series of color TV using Toshiba single chip small signal processing circuit TB1227N, due to the different control system software, divided into two circuits, two circuits store the number of different radio, bus system adjustment methods and adjustments are different, but two The circuit bus system is basically the same. Microprocessor N A01 (M37222M6-084SP) has 3 groups of bus outputs: The first group of NA01 is connected through 38-pin data line (SDA1) and 37?
