Therefore they haverequired that the DVD standard include codes which can be used to lock out the playback of certain discs in certain geo-graphicalregions. Players sold in each region will have that regionis code built into the player. The player will refuse to playthese region coded discs which are not allowed in the region. However, regional codes are entirely optional. Discs withoutcodes will play on any player in any country. Some studios have already announced that only their new releases will haveregional codes. There are six regions:1. United States and Canada2. Europe and Japan3. Far East (except Japan & China)4. South America and Oceania5. Africa and the Middle East6. China (except Hong Kong)2.

INFORMATIONSREGION CODETHE DISCS THAT THE DV7000 CAN HANDLEThe following discs can be played back with a DV7000.Note: The regional code of the discs must meet to the regionalcode of the DV7000.DVD INFORMATIONBelow is a glossary of the new terms related to DVD.Title:A disc may have more than one story/movie on it, so eachstory/movie is called a title.For example, if there are 2 movies on the disc, they areseparated into Title 1 and Title 2.Chapter:A title may also be separated into chapters.For example, a movie (title) may be separated into 3 scenes(chapters).Subtitles:DVDs are recorded with up to 32 different subtitle languages.If a disc has more than one subtitle language, you can selectthe subtitle language that you want to read.Soundtrack language:DVDs are recorded with up to 8 different soundtrack languages.If a disc has more than one language, you can select thesoundtrack language that you want to listen to.Multi-angles:On some DVDs, scenes have been filmed from different angles(up to a maximum of 9). On these discs, you can select theangle that you want to watch. Please refer to the DVDs manualto see which scenes have multi-angles.Cancelling password for parental press the DIMMER buttonand hold for 10 seconds while the player is stopped. discmarkplayback capabilitysizesideDVDAudio/Video12 cmsingle/double8 cmCDAudio12 cmsingle8 cm12 cmVCDAudio/Videosingle8 cmVERSIONREGION CODE COUNTRY /FXX2JAPAN /KXX6CHINA /NXX2EUROPE /SXX3SINGAPORE/HONGKONG /UXX1USA/CANADATitle 1Title 2Chapter3Chapter1Chapter2Chapter3Chapter1Chapter21-44.

DISASSEMBLY1. Open the tray and remove the escutcheon (050B).REMARK : If the tray doesnt work, put a smallscrewdriver into the hole as shown in pictureand slide the knob. Then the tray comes out.After the first centimeter it is possible to pullthe tray out by hand. (see fig.1)2. Remove 6 screws and remove the top cover.3. Remove a top right side screw on the power supply PCBand remove the GND lug wire.4. Remove 3 connectors of the wire harness from (or to )front panel assembly.5. Remove 2 screws of left and right side of the front panelassembly.6. Remove the front panel assembly.7. Remove the retainer on the DVD mechanism.8. Remove FFC and wire harness from the DVD main PCBwhich mounted under the DVD mechanism.9. Remove 4 screws and remove DVD mechanism module.Fig. 11-6STOPPER TUB6-1. Removal of the TRAVERSE MECHA.6-1-1. Removal of the MECHANISM BLOCK1) Turn the units power on and press the EJECT button toeject the DISC TRAY.2) Disconnect the power cord and remove the DISC CLAMPERBLOCK.3) Completely remove the DISC TRAY by pulling it outwardswhile pulling up both of the stopper tabs alternately.Fig. 6-14) Disconnect the two flat cables from the P803 connectorsand one flat cable from the P808 connector on the MAINPCB.5) Disconnect the P807 connector on the MAIN PCB.6) Remove the four a retaining screws and remove theMECHANISM BLOCK from the chassis.Fig. 6-2A SCREW6. REPLACEMENT OF PRINCIPAL COMPONENTS6-1-2. Removal of the TRAVERSE MECHA.1) Remove the four b screws on the MAIN PCB and thendisconnect the P800 connector on the MAIN PCB.Fig. 6-32) Short the laser diode protection circuit on the PICK UPBLOCKs flexible cable with solder as shown.CautionTo protect the laser diode from damage caused by high voltagestatic electricity, a laser diode protection circuit has to beshorted before disconnecting the flexible cable (P200 connectoron the MECHANISM PCB). It is recommended that you putsolder on the top of the soldering iron as shown in Fig. 3-5then short the circuit at once. When you replace the TRAVERSEMECHA., be sure to connect the P200 connector beforeremoving the solder at the shorted parts.B SCREWP200SOLDERFig. 6-4Fig. 6-51-73) Carefully disconnect the two connectors (P500, P600) andthe two flat cables (P200, P300) on the MECHANISM PCB.Fig. 6-64) Using tweezers, release the four retaining HOOKs of theTRAVERSE MECHA. from the rubber insulators beingcareful not to damage the rubber insulators.Fig. 6-75) Remove the TRAVERSE MECHA. from the MECHANISMBLOCK.6) Reassemble in the reverse order for installation. Neverremove the solder on the flexible cable before connectingthe P200 connector on the MECHANISM PCB.6-2. Replacement of the SPINDLE MOTORBecause the SPINDLE MOTOR position is very critical, jitteradjustment should be performed after replacement.1) Disconnect the P300 connector on the MECHANISM PCB.2) Insert a Philips type screw driver into the hole on the TURNTABLE of the SPINDLE MOTOR and remove the twoscrews.6-3. Replacement of the PICK UP BLOCKReplacement of the PICK UP BLOCK itself is notrecommended because its azimuth adjustment is verycritical and requires a special jig. If PICK UP BLOCKreplacement is necessary, replace with an entireTRAVERSE MECHANISM only.P200P300P600P5001-87. SERVICE MODEFLD,
