LD Short Terminal
2. Replacement of optical pick-up
The laser diode in the optical pickup block is so sensitive to static electricity, surge current and etc. that the components are liable to be broken down or its reliability remarkably deteriorated. During repair, carefully take the following precautions. 1. Solder the LD short terminal on mechanism. 2. Disconnect the flexible flat cable P101. 3. Replace the optical pickup. 4. Connect the flexible flat cable P101. 5. Unsolder the LD short terminal on mechanism.
Pick up short land
NOTE
1. Ground for the work-desk. Place a conductive sheet such as a sheet of copper (with impedance lower than 10Mohm) on the workdesk and place the set on the conductive sheet so that the chassis can be grounded. 2. Grounding for the test equipments and tools. Test equipments and toolings should be grounded in order that their ground level is the same the ground of the power source. 3. Grounding for the human body. Be sure to put on a wrist-strap for grounding whose other end is grounded. Be particularly careful when the workers wear synthetic fiber clothes, or air is dry. 4. Select a soldering iron that permits no leakage and have the tip of the iron well-grounded. 5. Do not check the laser diode terminals with the probe of a circuit tester or oscilloscope.
