一、光头组件损坏类别光头损坏常见的有三类,就是机械、电气、光学通道。机械故障表现为:镜头组件过度下陷被磁缸吸引造成镜间组件不能完成聚焦动作。处理方法:拆下护罩,用镊子把物镜提起。光学故障表现为:不读碟或打碟。故障原因是镜间被打花或表面镀膜被不标准的清洗剂破坏。处理方法:更换物镜或清洗物镜。电气故障表现为:主要是激光管失效。读碟困难 First, the bald component damage Category bald damage is common in three categories, that is, mechanical, electrical, optical channel. Mechanical failure manifested as: over-subsidence lens components are attracted by the magnetic cylinder mirror assembly can not complete the focusing action. Approach: Remove the shield, the objective lens with tweezers lift. Optical failure performance is: do not read the disc or playing disc. The reason is the failure of the mirror was playing flowers or surface coating is not standard cleaning agent damage. Remedy: Replace the objective lens or clean the objective lens. Electrical failure as follows: the main failure of the laser tube. Difficult to read the disc
