Use with caution to electrostatic breakdown when servicing and handling the laser diode. 9.1. Cautions to Be Taken in Handling the Optica

18、l Pickup Unit The laser diode in the optical pickup unit may be damaged due to electrostatic discharge generating from clothes or human body. Use with caution to electrostatic discharge damage when servicing the laser diode. 1. Do not give a considerable shock to the optical pickup unit as it has an

19、 extremely high-precise structure. 2. To prevent the laser diode from the electrostatic discharge damage, the flexible cable of the optical pickup unit removed from the PCB should be short-circuited with a short pin or a clip. 3. The flexible cable may be cut off if an excessive force is applied to

20、it. Use caution when handling the flexible cable. 4. The antistatic FPC is connected to the new optical pickup unit. After replacing the optical pickup unit and connecting the flexible cable, cut off the antistatic FPC. 9.2. Cautions to Be Taken When Replacing the Optical Pickup The flexible cable o

21、f the optical pickup unit which was supplied as a component is equipped with a short clip to prevent the laser diode from being damaged due to electrostatic discharge. Remove the short clip before connecting the flexible cableand make sure that the short land is open. (If the flexible cable is short

22、-circuited, remove the solder.) 9.3. Grounding for electrostatic breakdown prevention Some devices such as the DVD player use the optical pickup (laser diode) and the optical pickup will be damaged by static electricity in the working environment. Proceed servicing works under the working environmen

23、t where grounding works is completed. 9.3.1. Worktable grounding 1. Put a conductive material (sheet) or iron sheet on the area where the optical pickup is placed, and ground the sheet. 10 SA-HT670PC 9.3.2. Human body grounding 1. Use the anti-static wrist strap to discharge the static electricity f

Gear for servicing information This unit has a gear which used for checking items (open/close of disc tray, up/down operation of traverse unit by manually) when servicing. (For gear information, that is described on the items for disassembly procedures.) Forpreparationo

30、fgear(forservicing),performthe procedures as follows. In case of re-servicing the same set, the “gear for servicing” may be took off because it had been used. So, the “gear for servicing” must be stored. 1. Remove the gear attached to top cover of DVD loading mechanism. 2. Insert the hexagonal wrenc
