1. SERVICE PRECAUTIONS
• 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.
[ When removing the DVD Deck ]
Before removing Pick Up PCB and DVD MT PCB connector, the 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 installing the DVD Deck ]
Remove all the soldering on the short circuit position after the connection of Pick Up PCB and DVD
MT PCB connector.
NOTE
• Before your operation, please read "PREPARATION OF SERVICING"
• Use the Lead Free solder.
• Manual soldering conditions
• Soldering temperature: 320 ± 20oC
• 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 keep the
Flux smoke away from it.

Distinction of PbF PCB:
PCBs (manufactured) using lead free solder will have a PbF printing on the PCB.
(Please refer to figures.)
Caution:
Pb free solder has a higher melting point than standard solder;
Typically the melting point is 86oF~104oF(30oC~40oC) higher.
Please use a soldering iron with temperature control and adjust it to 650oF 20oF (350oC ±10oC).
Please use a soldering iron with temperature control and adjust it to 650oF ± 20oF (350oC ±10oC).
In case of using high temperature soldering iron, please be careful not to heat too long.
Pb free solder will tend to splash when heated too high (about 1100oF/ 600oC).
All products with the printed circuit board with PbF printing must be serviced with lead free solder.
When soldering or unsoldering, completely remove all of the solder from the pins or solder area,
and be sure to heat the soldering points with the lead free solder until it melts sufficiently.
Recommendations
Recommended lead free solder composition is Sn-3.0Ag-0.5Cu.

Case when this diagnosis is required :
When playback of any disc, including a test disc (DVD: GGV1025(NTSC)/GGV1101(PAL), CD: STD-905), cannot be performed
How to diagnose
In the case mentioned above, degradation of the laser diodes (LDs) mounted on the PICKUP Assy is suspected.
Measure the voltage between the two ends of one of the resistors mentioned below.
Measure the voltage between the two ends of NR2301 on the DVD MT PCB Assy.
If the voltage is 0.17 V or higher, the 650-nm LD is degraded.
No playback of a DVD :
Measure the voltage between the two ends of NR2301 on the DVD MT PCB Assy.
If the voltage is 0.20 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.

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.

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 47 k ohm (tolerance is shown by J = 5%,
and K = 10%).
560 Ω
