SAFETY INFORMATION

A

This service manual is intended for qualified service technicians ; it is not meant for the casual do-it-yourselfer. 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 may void the warranty. If you are not qualified to perform the repair of this pr oduct properly and safely, you should not risk trying to do so and refer the repair to a qualified service technician.

Additional Laser Caution

1.

• Laser diode is driving with Q2303,Q2305(650nm LD) and Q2302, Q2304(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.

2. When the cover is open, close viewing through the objective lens with the naked eye will cause exposure to the laser beam.

• 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.

[ Removing the DVD Deck ]

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.

[ 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

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

PREPARATION OF SERVICING

E

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.

About MPEG-4 AAC

Advanced Audio Coding (AAC) is at the core of the MPEG-4 AAC standard, which incorporates MPEG-2 AAC, forming the basis of the MPEG-4 audio compression technology. The file format and extension used depend on the application used to encode the AAC

®

file. This unit plays back AAC files encoded by iTunes extension ‘. encoded with some versions of iTunes

m4a

’. DRM-protected files will not play, and files

®

may not play, or filenames

bearing the

may display incorrectly.

WMA (Windows Media™ Audio) compatibility

This player can playback Windows Media Audio content. WMA is an acronym for Windows Media Audio and refers to an

audio compression technology developed by Microsoft Corporation.

WMA content can be encoded byusing Windows Media Player for Windows XP, Windows Media Player 9 or Windows Media Player 10

series.

•Windows Media is a trademark of Microsoft Corporation.

•This product includes technology owned by Microsoft Corporation and cannot be used or distributed without a license from Microsoft Licensing, Inc.

C

About DivX video

DivX is a media technology created by DivX, Inc. DivX media files contain not only video but also include advanced media features like menus, subtitles, and alternate audiotracks. This player can play DivX videos burned on CD-R/-RW/-ROM discs. Keeping the same terminology as DVD-Video, individual DivX video files are called “Titles”. When naming files/titles on a CD-R/-RW disc prior to burning, keep in mind that by default they will be played in alphabetical order.

D

DivX video compatibility

•Official DivX Ultra Certified product.

•Plays all versions of DivX video (including DivX 6) with enhanced playback of DivX media files and the DivX Media

®

Format.

•File extensions: .avi and .divx (these must be used for the player to recognize DivX video files).Note that all files with the .avi

extension are recognized as MPEG4, but not all of these are necessarily DivX video files and therefore may not be playable on

this player.

About WMV

WMV is an acronym for Windows Media Video and refers to a video compression technology developed by Microsoft Corporation. WMV

content can be encoded by using Windows Media Encoder.

®

•This player is compatible with WMV9 files that are encoded by using the Windows Media Encoder 9 Series, with .wmv as an

®

extension.

•Compatible with size under 720 x 576 pixels/720 x 480 pixels.

•Advanced Profile is not supported.

•DRM-protected video files will not play in this player.

JPEG file compatibility

•Compatible formats: Baseline JPEG and EXIF 2.2* still image files up to a resolution of 3072 x 2048.

*File format used by digital still cameras.

•Progressive JPEG compatible: No

•File extensions: .jpg (must be used for the player to recognize JPEG files–do not use for other file types)

PC-created disc compatibility

Discs recorded using a personal computer may not be playable in this unit due to the setting of the application software used to create the disc. In these particular instances, check with the software publisher for more detailed information.

Discs recorded in packet write mode (UDF format) are not compatible with this player.

Check the DVD-R/-RW or CD-R/-RW software disc boxes for additional compatibility information.

POWER DOES NOT TUNER ON

A

Is the voltage at pin 6 and 7 of CP502 about 4V and at pin 10 of CP502 about 5V?

Yes

Is the voltage at pin 4 of IC1701 about 3V and pin 3 of IC1702 about 1.8V ?

Yes

Is the voltage at pin 4 of IC1703 about 5V?

Yes

No

Check at 4V line of POWER BLOCK.Check IC503 and peripheral circuit.

Check of IC1701,1702.

Check of IC1703.
