综观目前国内用户使用的各种型号遥控彩电,其共同点是采用发光二极管来指示其工作状态,即通过整机面板上发光管是否发光及其发光强弱变化或颜色变化来区分整机是处于待机状态还是常规收视状态。而发光管又是受遥控电源、开关电源或行输出电路(包括保护电路)及遥控电路等正常工作控制的,即这四部分电路是否正常工作,指示灯的发光均有不同程度的差异。而遥控彩电三无故障,大多也是这四部
Looking at the current domestic users of various types of remote control color TV, the common ground is the use of light-emitting diodes to indicate its working status, that is, through the whole panel LED is luminous and its luminous intensity changes or color changes to distinguish the machine is in Standby or normal viewing status. The LED is controlled by the remote control power supply, switching power supply or line output circuit (including the protection circuit) and the remote control circuit and other normal work, that is, whether the four parts of the circuit are working properly or not, and the light of the indicator lamp has different degrees of difference. The remote control TV without problems, most of them are four
