故障现象:变焦镜头不能伸缩。按下快门,变焦镜头不能伸缩,当靠近相机时,能听到变焦马达的运转噪声,但镜头没有动作,这可能是变焦电机转动受阻或传动机构损坏造成的。故障分析:能听到变焦马达运转噪声,说明该马达已工作,变焦电机转动而变焦镜头不能伸缩,是由于镜头组件中已有元件损坏、变焦镜头传输机构无法传送 Symptom: zoom lens can not be scaled. When you press the shutter button, the zoom lens does not extend and retract. When you approach the camera, you can hear the operating noise of the zoom motor, but the lens does not move.
