彩电遥控失灵,多数是遥控器故障。因为遥控器经常使用,触摸频繁,易被汗、水、油污、灰尘等沾污。另外,摔跌、印制板断线、没有及时更换电池、电池流电解液等也会引起遥控器发生故障。由于遥控器电路的特殊性,维修时,不能仅凭测信号强度或信号通断来判断故障部位,所以有些维修人员感到无从下手。笔者根据多年维修彩电遥控器经验,总结出遥控器失灵故障检修方法,供大家参考。一、部分控制键接触不良或失灵。可用橡皮擦导电
Color TV remote control failure, most of the remote control failure. Because the remote control often use, touch frequently, easily sweat, water, oil, dust and other pollution. In addition, fell, printed circuit board disconnected, there is no timely replacement of the battery, the battery flow electrolyte can also cause remote control failure. Due to the particularity of the remote control circuit, when repairing, we can not judge the fault location by measuring the signal strength or the signal, so some maintenance personnel feel that it is impossible to start with. The author based on years of experience in the maintenance of color TV remote control, summed up the failure of remote control troubleshooting methods for your reference. First, some of the control keys poor contact or failure. Eraser can be conductive
