REGIONAL CODES1222554436Map of DVD RegionsWhat are regional codes?Motion picture studios want to control the home release of movies in different countries because theater releases arentsimultaneous (a movie may come out on DVD in the US when its just hitting screens in Europe). Therefore they haverequired that the DVD standard include codes which can be used to lock out the playback of certain discs in certain geo-graphical regions. Players sold in each region will have that regions 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 Canada 2. Europe and Japan 3. Far East (except Japan & China) 4. South America and Oceania 5. Africa and the Middle East 6. China (except Hong Kong)1-33. INFORMATIONSREGION CODETHE DISCS THAT THE DV-18 CAN HANDLEThe following discs can be played back with a DV-18.Note: The regional code of the discs must meet to the regionalcode of the DV-18.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).Title 1Title 2Chapter3Chapter1Chapter2Chapter3Chapter1Chapter2Subtitles: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 /SXX3SINGAPORE/HONGKONG /UXX1USA/CANADACodeDisc16D/V/C17D/V/C18D/V/C19D/V/C20V/C32D/V/C33D/V/C34D/V/C35D/V/C36D/V/C37D/V/C38D/V/CNo focus ON.Error DescriptionNo access with the Read channel (IC200).Access to CD-DSP(IC490) is not available.No access to the servo DSC (IC300).Sledge motor is not working.No tracking ON.D:DVD, V:VideoCD, C:CDNo access with the flash ROM (IC602).Sub code of CD,VCD is not readable.No access with the EEPROM (IC603).No access with the A/V Encoder (IC850).No access with the DEM/ECC (IC500).No access with A/V decoder (IC700).Error Code Table1-44.

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, LED TEST1.
