录像机是现代计算机技术、电子技术与精密机械有机结合的产品。它的突出特点是各项操作实现了智能化,因此,不仅电路部分较复杂,而且机械部分与其他家用电器相比也要复杂得多。实际上,机械部分的故障同样表现为声像质量差、部分控制功能失灵或完全不能工作,很容易与电路部分故障混淆而给检修者判断故障原因增加了一定难度。常常会由于忽视对机械部分的必要检查和处
VCR is a modern computer technology, electronic technology and precision machinery organic combination of products. Its salient features are intelligent operation, so not only are the circuit components more complicated, but the mechanical parts are much more complicated than other home appliances. In fact, the mechanical part of the failure of the same performance for the poor quality of audio and video, part of the control function fails or completely unable to work, it is easy to confuse with the circuit part of the fault and to repair the judge to determine the cause of the malfunction increased a certain degree of difficulty. Often due to neglect of the mechanical part of the necessary inspection and office
