SERVICE PRECAUTIONS 1.1 NOTES ON SOLDERING 1.2 WHEN REPLACING DVD DECK NOTES ON SOLDERING • For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit. Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs accompanied by reworking of soldering. • Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 ºC. Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 ºC in general, although the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of the soldering iron. Do NOT use a soldering iron whose tip temperature cannot be controlled. Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting temperatures (hard to melt/easy to harden). The following lead-free solders are available as service parts: • Parts numbers of lead-free solder: GYP1006 1.0 in dia. GYP1007 0.6 in dia. GYP1008 0.3 in dia. Before removing Pick Up PCB and DVD PCB connector, short circuit the position shown in Fig. 1 using a soldering iron. If you remove the DVD Deck with no soldering, the Laser may be damaged. WHEN REPLACING DVD DECK [ Removing the DVD Deck ] [ Installing the DVD Deck ] Remove all the soldering on the short circuit position after the connection of Pick Up PCB and DVD PCB connector. NOTE Fig. 1 Before your operation, please read “PREPARATION OF SERVICING” . Use the Lead Free solder. Manual soldering conditions • Soldering temperature: 320 ± 20˚C • Soldering time: Within 3 seconds • Soldering combination: Sn-3.0Ag-0.5Cu When Soldering/Removing of solder, use the draw in equipment over the Pick Up Unit to prevent the Flux smoke from it. • • • • Short circuit using a soldering iron.

Moreover, even if it is operating normally after repair, when static electricity discharge is received at the time of repair, the life of the product may be shortened. Please perform the following measure against static electricity, be careful of destruction of a laser diode at the time of repair. • Place the unit on a workstation equipped to protect against static electricity, such as conductive mat. • Soldering iron with ground wire or ceramic type is used. • A worker needs to use a ground conductive wrist strap for body.

Measure the voltage between the two ends of one of the resistors mentioned below. Measure the voltage between the two ends of R2321 or R2323 on the DVDM Assy. If the voltage is 0.4 V or higher, the 650-nm LD is degraded. No playback of a DVD : Measure the voltage between the two ends of R2320 or R2322 on the DVDM Assy. If the voltage is 0.4 V or higher, the 780-nm LD is degraded. No playback of a CD : If the measurements show degradation of an LD, replace the PICKUP Assy.

EACH SETTING AND ADJUSTMENT 8.1 ADJUSTMENT 8.2 RE-WRITE FOR DVD FIRMWARE There is no information to be shown in this chapter. 1. Purpose After replacing the DVD MT PCB Assy, be sure to update the firmware to the latest version. The firmware of the Assy for service may not be the latest. 3. Procedures for updating the firmware How to update: 1 Turn on the main unit and open the disc tray. 2 Place the disc for updating in the disc tray and close the tray. 3 Press the PLAY button. 4 Updating of the firmware is completed. 2. Procedures for creating the disc for updating Necessary tools: 1 PC with a CD-R/CD-RW drive 2 Blank CD-R or CD-RW 3 Firmware file (∗∗∗∗∗.BIN) How to create: 1 Start up the program for writing to CD. 2 Load a blank disc in the CD-R/CD-RW drive. 3 Enter "PIONEER" as the volume label. 4 Select the .BIN file. 5 Write the latest version of the firmware in ISO 9660 format. While the screen shown at left is being displayed, updating is in progress. DO NOT TURN OFF THE POWER DURING UPDATING. When the screen with the Pioneer logo is displayed, updating is completed. The time required for updating is about 2 minutes. 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 DV-48AV 41 5 6 7 8 5 6 7 8 C D F A B E 4. How to confirm the version of the firmware Press the ESC then the CHAP key on the remote control unit for servicing. The version of the firmware is labeled ROM NUMBER. Check if the version is the latest one. 5. Troubleshooting 1 If updating of the firmware failed If the main unit was turned off during updating, it cannot initialize and start up again properly. In such a case, replace the flash ROM on the DVD MT PCB Assy. 2 If updating of the firmware using the disc for updating failed • Was the disc for updating recognized properly? Check if the volume label of the disc is PIONEER. • Is playback of a disc other than the disc for updating possible? If playback of a test CD is also impossible, a reading section, such as PU, may be defective. In such a case, repair the defective part first. If playback of a test CD is possible, the disc for updating may be defective. Check for any scratches or foreign matter, such as fingerprints, on the reading surface. If no problem is found with the disc, create a new disc for updating again.

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 Ω 47k Ω 0.5 Ω 1 Ω RD1/4PU J RD1/4PU J RN2H K RS1P K 56 x 10 1 47 x 10 3 R50 1R0 561 473 5.62k Ω RN1/4PC F 562 x 10 1 5621 Mark No. Description Part No. LIST OF ASSEMBLIES 1..DVD MT PCB ASSY A2K512A130 1..OPERATION 1 PCB ASSY A2K512A270 1..OPERATION 2 PCB ASSY A2K401A280 1..OPERATION 3 PCB ASSY A2K401ADF0 > 1..POWER PCB ASSSY A2K512A240 1..USB PCB ASSY A2K401ADD0 1..DVD MECHA ASSY A2K001A650 Mark No. Description Part No. DVD MT PCB ASSY SEMICONDUCTORS IC2301 IC AM5766 I1UFV5766S IC4001 IC S-24CS08AFJ-TB-1GE I5HJ0S08A0 IC4002 IC MT1389EXE/S-L IC8K0389SX IC4003 IC R3112N291A-TR-FA IE1F0291A0 IC4004 IC ES29LV160EB-70TG S2K512AF01 IC4005 IC HY57V641620ETP-6 ICLJ0TP6C0 IC4006 IC LM1117S-ADJ I1TF911170 IC7301 IC LA73054-TLM I03FG30540 IC5902 IC PQ1K503M2ZPH I0GF9K5030 IC8001 IC TC7SHU04FU I55F00FU0 IC8002,IC8007,IC8008 IC RC4580IDR I04J045800 IC8003-IC8005 IC PCM1742KE/2K I17F0042KE0 OTHERS J7302 RCA JACK 060R451010 J7304 JACK DIN-409A 063R700013 J8001 RCA JACK 060R451009 J8002 RCA JACK 060R451011 CP5901 CONNECTOR PCB SIDE 0694YJ3018 X4001 CRYSTAL (27MHz) 100GT02720 OPERATION 1 PCB ASSY SEMICONDUCTORS IC651 IC PT6315 IF4K063150 SWITCHES SW652 - SW666 SWITCH TACT 0504R01T38 OTHERS V651 TUBE FLUORESCENT 096F82R601 OS651 REMOTE RECEIVER 077A040002 OPERATION 2 PCB ASSY SWITCHES SW667 SWITCH TACT 0504R01T38 OPERATION 3 PCB ASSY SWITCHES SW668 SWITCH TACT 0504R01T38 POWER PCB ASSY RESISTORS > R511 R,FUSE 68 OHM 1/4W R65584680J OTHERS J8102 RCA JACK RCA-117-01 060R401122 CP8102 CORD CONNECTOR 06E8223301 OS8101 OPTICAL DEVICE RFT5CB1 07AA000011 USB PCB ASSY SEMICONDUCTORS IC6601 RT9702-PB I4UF097020 OTHERS CP6603 CONNECTOR PCB SIDE 06G5AA1001 Mark No. Description Part No. 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
