THE AEL (ACCESSIBLE EMISSION LEVEL) OF THE LASER POWER OUTPUT IS LESS THAN CLASS 1 BUT THE LASER COMPONENT IS CAPABLE OF EMITTING RADIATION EXCEEDING THE LIMIT FOR CLASS 1. A SPECIALLY INSTRUCTED PERSON SHOULD DO SERVICING OPERATION OF THE APPARATUS. LASER DIODE CHARACTERISTICS FOR DVD : MAXIMUM OUTPUT POWER : 5 mW WAVELENGTH : 650 nm FOR CD : MAXIMUM OUTPUT POWER : 7 mW WAVELENGTH : 780 nm Additional Laser Caution * : Refer to page 23. on the service manual RRV2905. LABEL CHECK REAR (DRW2168) 1. Laser Interlock Mechanism The position of the switch (S651) for detecting loading state is detected by the system microprocessor, and the design prevents laser diode oscillation when the switch (S651) is not on CLMP terminal side (CLMP signal is OFF or high level). Thus, the interlock will no longer function if the switch (S651) is deliberatery set to CLMP terminal side. (low level) The interlock also does not function in the test mode ]. Laser diode oscillation will continue, if pin 33 of CXA1782CQ (IC151) on the MOTHER BOARD ASSY is connected to GND, or pin 26 of IC351 (LDON) is connected to low level (ON), or else the terminals of Q151 are shorted to each other (fault condition). 2. When the cover is opened, close viewing of the objective lens with the naked eye will cause exposure to a Class 1 laser beam. www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com 3 1 2 3 4 1 2 3 4 C D F A B E PD-M427 [ Important symbols for good services ] In this manual, the symbols shown-below indicate that adjustments, settings or cleaning should be made securely.

PCB PARTS LIST Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List. The mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when replacing, be sure to use parts of identical designation. When ordering resistors, first convert resistance values into code form as shown in the following examples. Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%, and K=10%). Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5 6 1 4 7 3 R 5 0 1 R 0 5 6 2 1 NOTES: 560 47k 0.5 1 RD1/4PU J RD1/4PU J RN2H K RS1P K 56 x 101 47 x 103 R50 1R0 561 473 5.62k RN1/4PC F 562 x 101 5621 MOTHER BOARD ASSY PWM2155 NSP SUB BOARD ASSY PWX1337 FUNCTION BOADR ASSY PWZ2769 NSP SW BOARD ASSY PWZ2805 NSP MULTI MECHANISM ASSY PXA1592 NSP MECHA BOARD ASSY PWX1279 NSP LOADING BOARD ASSY PWZ2038 NSP MOTOR BOARD ASSY PWZ2040 NSP SELECT BOARD ASSY PWZ2533 NSP SERVO MECHANISM ASSY M PXA1595 NSP MECHANISM BOARD ASSY PWX1192 LIST OF WHOLE PCB ASSEMBLIES Mark Symbol and Description Part No. PD-M427/RFXJ Remarks Mark No. Description Parts No. Mark No. Description Parts No. 7 PARTS LIST FOR PD-M427/RFXJ MOTHER BOARD ASSY SEMICONDUCTORS IC151 CXA1782CQ IC301 CXD2519Q IC31, IC34 ICP–N10 IC201, IC202 LA6520 IC405 NJM4558D–D IC351 PD4836A IC21 PQ05RR12 Q151 2SA854S Q403, Q404 2SD2144S Q152 DTA124ES Q341 2SK246 Q405 DTC124ES D352, D341, D391- D394 1SS254 D54 MTZJ18B D359 MTZJ5.1B D218 MTZJ6.2B D11–D14, D52 S5688G COILS AND FILTERS L351 AXIAL INDUCTOR LAU100J L391 INDUCTOR LAU1R0J CAPACITORS C181 CCCCH100D50 C341, C342 CCCCH120J50 C383 CCCSL181J50 C393 CCCSL101J50 A www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com 21 5 6 7 8 5 6 7 8 C D F A B E PD-M427 CN701 FFC CONNECTOR 32P 9607S–32F V701 FL INDICATOR TUBE PEL1084 REMOTE SENSOR SBX1785–51 SW BOARD ASSY SEMICONDUCTOR D801 PCX1019 SWITCH S801 PSG1006 OTHER J801 2mm JUMPER WIRE D20PWW0420E LOADING BOARD ASSY SWITCHES S601, S602 DSG1016 OTHER CN601 CONNECTOR 4P 4–173979–4 MOTOR BOARD ASSY OTHER CN602 6PJUMPER CONNECTOR 52151–0610 SELECT BOARD ASSY SWITCHES S604–S606 DSG1016 S603 PSG1010 MECHANISM BOARD ASSY SWITCH S610 DSG1016 OTHER CN610 MT 4P CONNECTOR 173979–4 C315 CCCSL221J50 C481, C482 CCCSL390J50 C309 CEASR47M50 C171, C175, C302, C311, C314 CEAS101M10 C316, C312, C313 CEAS101M10 C52 CEAS101M35 C26 CEAS102M16 C433, C434 CEAS220M25 C131– C133, C27 CEAS330M16 C25 CEAS332M16 C351 CEAS471M6R3 C169, C170, C356 CEAS4R7M50 C156, C161, C164, C168, C218 CGCYX103K25 C160 CGCYX333K25 C167 CGCYX472K25 C152, C307 CGCYX473K25 C157 CGCYX823K25 C163 CKCYB102K50 C176, C306, C441, C442 CKCYB152K50 C305 CKCYB222K50 C162 CKCYB332K50 C151 CKCYB682K50 C11, C13, C15, C16, C17 CKCYF103Z50 C159, C205, C210, C215 CKCYF103Z50 C219, C301, C304, C310 CKCYF103Z50 C353, C357 CKCYF103Z50 C153– C155, C158 CQMA104J50 RESISTORS VR153, VR155 (10k Ω) VCP1156 VR151, VR152, VR154 (22k Ω) VCP1158 VR156 (220k Ω) VCP1164 Other Resistors RD1/4PU&&&J OTHERS CN131 1mm CONNECTOR SLW16S–1C7 CN202 MT 4P CONNECTOR 173981–4 CN203 CONNECTOR 4P 4–173981–4 CN204 6P JUMPER CONNECTOR 52147–0610 CN351 32P FFC CONNECTOR HLEM32S–1 JA401 2P PIN JACK PKB1023 X341 XTAL RES(16.9344 MHz) PSS1008 TERMINAL RKC–061 CN201 CONNECTOR 6P RKP–533 X351 CERAMIC RES(4.19 MHz) VSS1014 S5 Voltage Selector PSB1006 JA391, JA392 SR JACK RKN1004 FUNCTION BOARD ASSY SEMICONDUCTOR D701– D703 1SS133X SWITCHES S701– S710 PSG1006 OTHERS C F E B Mark No. Description Part No. Mark No. Description Part No. D G www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com 22 1 2 3 4 1 2 3 4 C D F A B E PD-M427 6.
