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.

EACH SETTING AND ADJUSTMENT 8.1 ADJUSTMENT 8.2 RE-WRITE FOR 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. The "DVD MT PCB ASSY" of this model includes two types of firmware for main processor and sub processor, and therefore it is necessary to update each firmware. When creating firmware update disc, two discs of CD-R/CD-RW need to be prepared and each firmware needs to be separately burned into each disc. And when updating both types of firmware, update the firmware for sub processor, and then update the firmware for main processor. * Both types of firmware cannot be updated simultaneously. * It is not necessary to update the firmware if the latest firmware versions are already stored in "DVD MT PCB ASSY". If either one of the two is the previous version, only the previous version needs to be updated. * The disc creation procedure and update procedure are the same for both types of firmware. 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-LX50 49 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 and Subcon. 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(WYXZT5) A2K802A130 1..DVD MT PCB ASSY(WYXZTUR5)A2K807A130 1..AUDIO PCB ASSY A2K802AF70 1..REAR JACK PCB ASSY A2K802A250 1..OPERATION 1 PCB ASSY A2K802A270 1..OPERATION 2 PCB ASSY A2K802A280 1..OPERATION 3 PCB ASSY A2K802ADF0 > 1..POWER PCB ASSSY A2K802A240 1..DVD MECHA ASSY A2K802A650 (*) A2K802A130 and A2K807A130 have same service parts.
