Additional Laser Caution 1. · Laser diode is driving with Q2303 (650nm LD) and Q2302(780nm LD) on the DVD MT PCB 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.

Please check that neither solder debris nor screws remain inside the product. 8 There should be no semi-broken wires, scratches, melting, etc. on the coating of the power cord. Damaged power cords may lead to fire accidents, so please be sure that there are no damages. If you find a damaged power cord, please exchange it with a suitable one. 9 There should be no spark traces or similar marks on the power plug.
D C B
When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure connections and suitable usage. Please exchange the power cord if necessary. a Safe environment should be secured during servicing. When you perform repairs, please pay attention to static electricity, furniture, household articles, etc. in order to prevent injuries. Please pay attention to your surroundings and repair safely.
2. Adjustments
To keep the original performance of the products, optimum adjustments and confirmation of characteristics within specification. Adjustments should be performed in accordance with the procedures/instructions described in this manual.
3. Lubricants, Glues, and Replacement parts
Use grease and adhesives that are equal to the specified substance. Make sure the proper amount is applied.
E
4. Cleaning
For parts that require cleaning, such as optical pickups, tape deck heads, lenses and mirrors used in projection monitors, proper cleaning should be performed to restore their performances.
5. Shipping mode and Shipping screws
To protect products from damages or failures during transit, the shipping mode should be set or the shipping screws should be installed before shipment. Please be sure to follow this method especially if it is specified in this manual.

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).
B A
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.
PARENTAL CONTROL - RATING LEVEL
4 DIGIT PASSWORD CANCELLATION
If the stored 4 digit password in the Rating Level menu needs to be cancelled, please follow the steps below. 1. 2. 3. 4. Set the DVD to the Stand-by Mode. Press and hold the 'STOP' key on the front panel. Simultaneously press and hold the POWER key on the front panel. The 4 digit password has now been cleared.
C
NOTE: The above procedure will reset ALL of the player's settings to the default factory state.
PREPARATION OF SERVICING
The laser diode used for a pickup head may be destroyed with external static electricity. 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.

Symptoms That May Occur When Any Of The Following ICs Is In Failure
IC Symptoms
The power cannot be turned on. 16M Flash ROM (DVD MT PCB Assy : IC4004) Downloading of the firmware cannot be performed. Any kind of symptoms (no power, a failure in any of the servo, video and audio systems, etc.) may be DVD IC (DVD MT PCB Assy : IC4001) generated, because the DVD processing is performed by a single chip. No power. 64M SDRAM (DVD MT PCB Assy : IC4005) Block noise is generated during playback.

5.2 METHOD FOR DIAGNOSING DEGRADATION OF THE LDS ON THE PICKUP ASSY
A
Case when this diagnosis is required : When playback of any disc, including a test disc (DVD: GGV1025, 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.
No playback of a DVD :
Measure the voltage between the two ends of NR2301 on the DVD MT PCB Assy. If the voltage is 0.17 V or higher, the 650-nm LD is degraded.
B
No playback of a CD :
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.
If the measurements show degradation of an LD, replace the PICKUP Assy.

8. EACH SETTING AND ADJUSTMENT
8.1 RE-WRITE FOR DVD FIRMWARE
A
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.
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.
B
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.
While the screen shown at left is being displayed, updating is in progress. DO NOT TURN OFF THE POWER DURING UPDATING.

5. Troubleshooting
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. 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.
