Qualified technicians have the necessary test equipment and tools, and have been trainedto properly and safely repair complex products such as those covered by this manual.Improperly performed repairs can adversely affect the safety and reliability of the product and mayvoid the warranty. If you are not qualified to perform the repair of this product properly and safely, youshould not risk trying to do so and refer the repair to a qualified service technician. WARNING ! 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. B LASER DIODE CHARACTERISTICS FOR DVD : MAXIMUM OUTPUT POWER : 5 mW WAVELENGTH : 650 nm FOR CD : MAXIMUM OUTPUT POWER : 5 mW WAVELENGTH : 780 nm C LABEL CHECK D Additional Laser Caution (Printed on the Rear Panel) E 1. Laser Interlock Mechanism • Loading switch (S101 on the LOAB Assy) is used for interlock mechanism of the laser. When this switch turned ON in SW2 (CLOSE) side (OPEN signal is 0V and CLOSE signal is 3.5V), a laser becomes the status which can completely oscillation. Furthermore, the laser completely oscillates in the disc judgment and disc playback. When player is power ON state and laser diode is not completely oscillating, 780nm laser diode is always oscillating by half power. • Laser diode is driving with Q7 (650nm LD) and Q8 (780nm LD) on the DVDM Assy. Therefore, when short-circuit between the emitter and collector of these transistors or the base voltage is supplied for transistors turn on, the laser oscillates. (failure mode) • In the test mode ∗ , there is the mode that the laser oscillates except for the disc judgment and playback. LD ON mode in the test mode oscillates with the laser forcibly. The interlock mechanism mentioned above becomes invalid in this mode. 2. When the cover is open, close viewing through the objective lens with the naked eye will cause exposure to the laser beam.

PCB PARTS LIST NOTES: 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%). 560 Ω 56 x 10 1 RD1/4PU 5 6 1 J 561 47k Ω RD1/4PU 4 7 3 J 47 x 10 3 473 0.5 Ω RN2H R 5 0 K R50 1Ω RS1P 1 R 0 K 1R0 Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5.62k Ω 562 x 10 1 5621 RN1/4PC 5 6 2 1 F Mark No. Description Part No. LIST OF ASSEMBLIES NSP 1..04 LOADER ASSY NSP 2..LOAB ASSY VWT1210 VWG2346 1..DVDM ASSY VWS1585 1..JCKB ASSY VWV1995 NSP 1..FLKB ASSY 2..FLKY ASSY 2..PWSB ASSY VWM2281 VWG2511 VWG2482 > VWR1377 1..POWER SUPPLY UNIT Mark No. Description A Part No. IC203 Q482, Q492, Q562 Q372, Q373 Q371, Q4, Q481, Q491, Q901 VYW2197 2SA1576A 2SA1602A 2SC4081 Q541–Q546 Q401 Q7, Q8 Q592 Q5 2SD2114K DTC114YUA HN1A01F HN1C01FU UM5K1N Q561 D471–D474, D481, D801 D591 UMH9N 1SS355 UDZS6R8(B) B C COILS AND FILTERS L421, L422 CHIP BEADS L311 CHIP BEADS Mark No. Description Part No. A LOAB ASSY [VWG2346] SWITCHES AND RELAYS S101 VSK1011 VTL1089 VTL1095 CAPACITORS C292, C293, C297 C265 C142, C227 C294, C295, C903 C507, C515, C516 CCSRCH101J50 CCSRCH220J50 CCSRCH221J50 CCSRCH330J50 CCSRCH331J50 C254 C211, C212 C251 C252 C256, C471, C506 CCSRCH391J50 CCSRCH561J50 CCSRCH8R0D50 CCSRCH9R0D50 CEAT100M50 C401, C405, C454, C511, C512 C517, C804, C911 C281, C421, C422, C501 C901 C201, C202, C237, C302, C73 CEAT101M10 CEAT101M10 CEAT102M6R3 CEAT1R0M50 CEAT221M6R3 C10, C203, C206, C215 C521, C522, C531, C591, C801 C9 C423, C424 C11, C124, C230, C267, C296 CEAT470M16 CEAT470M16 CEAT470M16 CEAT471M6R3 CKSRYB102K50 C298, C304, C505, C913 C130, C134, C136, C226 C313 C219 C209 CKSRYB102K50 CKSRYB103K50 CKSRYB105K10 CKSRYB152K50 CKSRYB153K25 C112–C114, C513, C514 C269 C208, C210 C258, C259 C255 CKSRYB222K50 CKSRYB333K16 CKSRYB472K50 CKSRYB473K50 CKSRYB474K10 D OTHERS CN602 KR CONNECTOR CN601 KR CONNECTOR PC BOARD LOAB S2B-PH-K S5B-PH-K VNP1879 B DVDM ASSY [VWS1585] SEMICONDUCTORS > IC321 IC502 IC204 IC202 IC101 BA00BC0WT BA4560F BR24L16FV-W K4S641632H-TC75 M63018FP IC471 IC472 IC451 IC401 IC201 MM1505XN MM1507XN MM1566AJ MM1623BF MT1389EE-L1 > IC801 NJM78M05FA PCM1742KE PQ1M505M2SPQ PST3228 S-L2980A33MC-C6S IC501 > IC311 IC205 > IC341 IC841 TC7SHU04FU 6 F 43 DV-470-S 5 E 7 8 1 Mark No. 2 Description 3 Part No. Mark No. 4 Description Other Resistors A B C125, C204, C205, C207 C213, C214, C216, C217, C220 C222–C225, C228, C231–C236 C239–C241, C244–C246, C253 C257, C260, C262, C264, C266 CKSRYF104Z25 CKSRYF104Z25 CKSRYF104Z25 CKSRYF104Z25 CKSRYF104Z25 C268, C270–C273, C282 C284–C288, C290, C312, C402 C404, C411, C415, C416, C453 C461–C463, C472–C476, C482 C492, C502, C532, C71, C72 CKSRYF104Z25 CKSRYF104Z25 CKSRYF104Z25 CKSRYF104Z25 CKSRYF104Z25 C74 C102, C132, C139, C243, C261 C263, C283, C289, C303, C311 C321, C341, C342, C412–C414 C43–C46, C504, C518 CKSRYF104Z25 CKSRYF105Z10 CKSRYF105Z10 CKSRYF105Z10 CKSRYF105Z10 C592, C593, C6, C841, C912 CKSRYF105Z10 OTHERS CN941 4P MINI DIN SOCKET CN901 FFC CONNECTOR 17P JA902 RGB CONNECTOR D AKP7045 HLEM17S-1 VKB1157 D FLKY ASSY [VWG2511] SEMICONDUCTORS IC101 PE5374B SWITCHES AND RELAYS S105–S108, S117, S119 VSG1024 CAPACITORS C183 C151–C153 C102, C105, C182 C104 RESISTORS C Part No. RS1/16S###J CKSRYB102K50 CKSRYB103K50 CKSRYF104Z25 CKSRYF104Z50 R222, R225 R515, R520 R511, R514 R207–R209, R217 R904 RAB4C330J RN1/16SE1002D RN1/16SE5601D RS1/10S0R0J RS1/10S151J R562 R103, R106 R104, R107 R115–R120 R421–R424 RS1/10S182J RS1/10S1R0J RS1/10S1R8J RS1/10S4R7J RS1/10S75R0F R262, R264, R268, R271, R274 R277 R279 R321–R323 R905 RS1/16S1500F RS1/16S1500F RS1/16S2201F RS1/16S3302F RS1/16S75R0F E PWSB ASSY [VWG2482] Other Resistors RS1/16S###J F POWER SUPPLY UNIT [VWR1377] RESISTORS All Resistors RS1/16S###J OTHERS IC104 REMOTE RECEIVER UNIT V101 FLUORESCENT TUBE CN101 15P CONNECTOR 0 CONNECTOR ASS'Y(2P) X101 (5MHz) RPM7240-H4 VAW1078 VKN1246 VKP2322 VSS1142 SWITCHES AND RELAYS S101 OTHERS VSG1024 OTHERS CN301 CONNECTOR CN103 CONNECTOR POST CN451 CONNECTOR POST JA501 JACK JA401 JACK B13B-PH-K B5B-PH-K HLEM17S-1 VKB1132 VKB1168 CN104 4P CONNECTOR CN102 12P CONNECTOR CN201 15P CONNECTOR CN101 24P CONNECTOR JA901 JACK VKN1235 VKN1243 VKN1246 VKN1464 VKX1013 X201 VSS1168 > CP1 PROTECTOR (800mA) AEK7008 E (27MHz) C JCKB ASSY [VWV1995] SEMICONDUCTORS D991–D994 1SS355 CAPACITORS C911, C912 C901–C904,C942 C914, C941 F CCSRCH331J50 CEAT471M6R3 CKSRYF104Z25 RESISTORS R903, R906, R907, R909, R910 R941, R942 RS1/10S75R0F RS1/10S75R0F 44 DV-470-S 1 2 3 4 5 6 7 8 6.
