故障现象:光盘进、出仓正常,但不能读盘。分析与检修:卸开机盖检查,发现聚焦,循迹动作均正常,激光头也有激光发出,但发现主轴电机不转。导致主轴电机不转的原因很多,但据以往的检修经验判断主要多是其驱动电路和主轴电机,以及电源电路,供电不良所致。另外,也可能是激光头组件或其附属电路有问题。但从初步检查的结果来看激光头组件有故障的可能性不大,应重点检查电源电路和主要主轴 Symptom: CD into, out of storage normal, but can not read the disk. Analysis and Maintenance: Unfold the cover inspection, found that focus, tracking movements are normal, laser head laser also issued, but found spindle motor does not turn. Lead to spindle motor does not turn for many reasons, but according to previous maintenance experience to determine mostly the main drive circuit and the spindle motor, and power circuits, poor power supply. In addition, there may be problems with the laser head module or its accessory circuits. However, the results of the initial inspection laser head assembly is unlikely to fail, should focus on checking the power supply circuit and the main spindle
