Laser crystals are delicate elements. To prevent damage to the laser diode
1. Do not touch the area around the laser diode or actuator;
2. Do not verify the laser diode with a tester or other device (the laser diode will break easily);
3. Short circuit of the laser pickup.
* Do not forget to remove the bridge (short circuit diode) after finishing the repair, and leave that open.
* Recommendation tool: welder.
* No Warranty.
