17、Handling Semi- conductors Electrostatic breakdown of the semi-conductors may occur due to a potential difference caused by electrostatic charge during unpacking or repair work. 1. Ground for Human Body Be sure to wear a grounding band (1 M) that is properly grounded to remove any static electricity

18、that may be charged on the body. 2. Ground for Workbench Be sure to place a conductive sheet or copper plate with proper grounding (1 M) on the workbench or other surface, where the semi-conductors are to be placed. Because the static electricity charge on clothing will not escape through the body g

19、rounding band, be careful to avoid contacting semi-conductors with your clothing. Example : Pin 1 of the Flat Pack-IC is indicated by a mark.

What to do for preparation Insert a tape into the Deck Mechanism Assembly and press the PLAY button. The tape will be loaded into the Deck Mechanism

25、Assembly. Make sure the power is on, connect TP502 (S-INH) to GND. This will stop the function of Tape Start Sensor, Tape End Sensor and Reel Sensors. (If these TPs are connected before plugging in the unit, the function of the sensors will stay valid.) See Fig. 1. Note: Because the Tape End Sensors

26、 are inactive, do not run a tape all the way to the start or the end of the tape to avoid tape damage.

46、5) Refer to “Reference Notes.” Reference Notes 1.CAUTION 1: Locking Tabs (L-1) and (L-2) are fragile. Be careful not to break them. 1) Release three Locking Tabs (L-1). 2) Release three Locking Tabs (L-2), then remove the Front Assembly. 2.CAUTION 2: Electrostatic breakdown of the laser diode in the

47、 optical system block may occur as a potential difference caused by electrostatic charge accumulated on cloth, human body etc., during unpacking or repair work. To avoid damage of pickup follow next procedures. 1) Disconnect Connector (CN301). Remove Screws (S-6) and lift the DVD Main CBA Unit. (Fig

48、. D4) 2) Short the three short lands of FPC cable with solder before removing the FFC cable (CN201) from it. If you disconnect the FFC cable (CN201), the laser diode of pickup will be destroyed. (Fig. D4) 3.CAUTION 3: When reassembling, confirm the FFC cable (CN201) is connected completely. Then rem

49、ove the solder from the three short lands of FPC cable. (Fig. D4) 4.When reassembling, solder wire jumpers as shown in Fig. D6. 5.Before installing the Deck Assembly, be sure to place the pin of LD-SW on Main CBA as shown in Fig. D6. Then, install the Deck Assembly while aligning the hole of Cam Gear with the pin of LD- SW, the shaft of Cam Gear with the hole of LD-SW as shown in Fig. D6. ID/ Loc.
