Assembling and Disassembling the Optical Pickup (Mechanical Parts) The optical pickup can be damaged by static electricity from your body. Be sure to take static electricity countermeasures when working around the optical pickup. 2-1 Handling the Optical Pickup The optical pickup can be damaged by static electricity from your body. Be sure to take static electricity counter- measures when working around the optical pickup. 1. The optical pickup is an extremely high-precision mecha- nism. Do not subject it to strong impact. 2. To preserve the quality of the optical pickup replacement parts during transport and installation, the terminals of the laser diode are short-circuited. After replacing the parts, use the proper procedure to return the laser diode to its original condition. (Refer to page8/2-11 Assembling the Optical Pickup.) 3. Testers cannot be used to check the laser diode of the optical pickup. The power supply inside the tester can easily damage the laser diode. 4. Take care when handling the flexible cable because excessive force can cause it to break. 5. You cannot adjust the semifixed resistor for laser power adjustment. Do not turn it. 2-2 Disassembly Procedure Use the following procedure to replace major parts. For the assembly procedure, follow the flow chart in reverse. 3. Checked by connecting the module C.B.A. and the moth- er C.B.A. with the extension cables. Extension cable (B)x2 Module C.B.A. Mother C.B.A. PS3201-PP3201 PS4201-PP4201 4. Checked by connecting the mechanism loading C.B.A. and the mother C.B.A. with the extension cables. Extension cable(C) Mechanism Loading C.B.A. Mother C.B.A. PS2591-PP4201 Note Be sure to initialize the player whenever you replace a C.B.A. (Refer to page17/4-1, Initializing the DVD player.) DVF-3030 6 DISASSEMBLY FOR REPAIR 2-3 Static Electricity Countermeasures The laser diode inside the traverse unit (optical pickup) can be damaged by static electricity from your body. Be sure to take static electricity countermeasures when working around the optical pickup. 2-3-1 Static Electricity Countermeasure Methods 1. Ground yourself Use an anti-static wrist strap to discharge static electrici- ty from your body. 2. Ground the workbench Lay a conductive material (sheet) or steel sheet on the surface where the traverse unit (optical pickup) is to be placed, then ground the sheet. 2-4 Disassembling the Clamp Base Unit Remove the 2 screws. 2-5 Disassembling the Clamper Weight, Clamper Yoke, Magnet and Clamper 1. Release the tab, and pull out the clamper. 2. Release the 3 tabs on the clamper. 2-3-2 Short-circuit the laser diode Solder the land in the flexible cable of the optical pickup. Notes Be sure to do this before disconnecting the flexible cable of the optical pickup from the module C.B.A. Use an anti-static soldering iron to short-circuit and unshort-circuit laser diode. (Recommended soldering iron: Hakko with ESD counter- measure) After you have finished repairing the laser diode, follow the correct procedure to remove the solder from the short-circuit location. (Refer to page5/2. Assembling and Disassembling the Optical Pickup (Mechanical Parts).) DVF-3030 7 DISASSEMBLY FOR REPAIR 2-6 Disassembling the Traverse Unit 1. Remove the 3 screws. Note Be sure to take static electricity countermeasures befer disconnecting the flexible cable.(Refer to page6/2-3 Stat- ic Electricity Countermeasures.) 2. Disconnect the 2 flexible cables. 2-7 Disassembling the Stepping Motor Unit 1. Disconnect the flexible cable. 2. Remove the 2 screws. Note Take care when handling the flexible cable because it can be broken by excessive force. 2-8 Disassembling the Optical Pickup Unit 1. Remove the screw. 2. Release the tab, then remove spring holder 1. Note Be sure not to lose the spring. 3. Remove the guide shaft. Note Be sure to adjust the optical pickup tilt after replacing the optical pickup. (Refer to page9/2-13 Optical Pickup Tilt Adjustment.) DVF-3030 8 DISASSEMBLY FOR REPAIR 2-9 Disassembling the Nut Unit 1. Remove the screw. Notes The nut unit is not part of the optical pickup. Before replacing the optical pickup, remove the nut unit for use with the new optical pickup. After installation, use screw lock to lock the screw in posi- tion. When reassembling, use screw lock to lock the screw in position after attaching it. 2-11 Assembling the Optical Pickup 1. Install the optical pickup. Note Take care not ot attach the tilt spring and guide shaft in the wrong order. 2-10 Disassembling the Sub-Shaft Preload Spring 1. Remove the screw. Notes Handle the sub-shaft preload spring carefully because the shape of the tip is easily deformed. The sub-shaft preload spring is not part of the optical pickup. Before replacing the optical pickup, remove the sub-shaft preload spring for use with the new optical pickup. After installation, use screw lock to lock the screw in posi- tion. 2. Insert the pickup FPC into connector FP5201 on the mod- ule C.B.A. DVF-3030 9 DISASSEMBLY FOR REPAIR 2-13 Optical Pickup Tilt Adjustment3. Remove the solder from the pickup FPCs soldered short- circuit. 4. Adjust the optical pickup tilt after removing the solder. (Refer to page 9/2-13 Optical Pickup Tilt Adjustment.) 2-12 Disassembling the Spindle Motor Unit 1. Remove the three screws. Note Be sure to adjust the optical pickup tilt after replacing the spindle motor unit. DVF-3030 10 DISASSEMBLY FOR REPAIR Notes Adjustment is generally unnecessary after replacing other parts of the traverse unit. However, adjust if there is a noticeable degradation in picture quality. Optical adjustments cannot be made inside the optical pickup. Adjustment is generally unnecessary after replacing the traverse unit.
