徒弟:师傅!请讲彩电遥控系统的基本组成电路及故障检修特点。师傅:彩电遥控系统电路类型甚多,并因机而异,但遥控系统的基本组成电路和工作原理以及故障检修方法却大致相同。一般遥控系统电路由红外遥控发射器、红外遥控接收器、微处理器、外存储器、以及接口电路等组成,其中微处理器是整个系统的控制中心,因此称作CPU。遥控电路的常见故障主要有:(1)不能遥控开/关
Apprentice: Master! Please tell the basic components of color TV remote control circuit and troubleshooting features. Master: color TV remote control circuit type many, and vary from machine to machine, but the basic components of the remote control circuit and working principle and troubleshooting methods are roughly the same. The general remote control system circuit consists of infrared remote control transmitter, infrared remote control receiver, microprocessor, external memory, and interface circuits, etc., of which the microprocessor is the control center of the entire system, so called CPU. Remote control circuit common faults are: (1) can not be remote on / off
