How to judge the damage of the laser head: The damage of the laser head generally means that it does not read the disc or it is very difficult to read the disc. Some discs with poor quality cannot be read at all. When the device can normally recognize the machine, it is usually a laser head. When the above situation occurs, you only need to disassemble the laser head to check the model of the laser head, and then purchase the corresponding model of bald head to install it, and the machine can be restored as new. 2. How to judge the model of the laser head: Generally, there is a model on the label of the laser head or on the base. If not, you can take the picture of the bald head and send it to us, and we will have professional technicians to confirm the model for you . Please confirm the model of the laser head you need before purchasing, so as to avoid accidental shooting. 3. How to install the laser head: When installing the laser head on the shelf, do not move the balance bar on the shelf. When disassembling the laser head, you only need to adjust one screw of the balance bar on one side, and do not adjust the other side, so as not to affect the balance, otherwise the laser head may not read the disc. If you can't install it yourself, you can ask a professional to test the installation after purchase to avoid damage to the laser head and the machine. 4. How to open the solder joints: When the laser head is shipped from the factory, in order to prevent static electricity from damaging the laser tube, there are generally protective solder joints (a larger solder joint on the bald circuit board or on the flexible cable). The power supply pin of the laser tube is short-circuited to the ground. Before installing the bald head, it needs to be welded with an anti-static soldering iron. Heat the soldering iron to about 250°C-280°C, disconnect the power supply, and then open the protective point, otherwise the laser head Will be unavailable.. Package List: 1 x Single Optical Pickup
