Fasten Screw A so that the interval (a) will be about 5.2mmand the interval (b) will be about 2.6mm. (The interval (a)can be measured using a pair of vernier calipers or similartools.)2. Turn B so that Position (c) will come at about the center ofinterval (d).3. Then, play the test disc and fine tune A or B so that the jittervalue would be minimized.NOTES ON ASSEMBLING THE MECHANISM2.6mm5.2mmAabBcdKVT-817DVD/827DVD/827DVDYKVT-837DVD/847DVD/867DVD3BLOCK DIAGRAMSRAMSH-3u-COMGRAPHICCHROMAGAMMA ICSDRAMSYSCON SDRAMRGB SWFLASHSDRAMMOTORDRIVERMPEGDECODERGENERATORCLOCKVIDEOENCODERSWCOMPOSITEFLASHCPLDAUDIODACSPDIFCIRCUITINVERTERTIMINGCONTROLLERTOUCHCONTROLLCDTOUCHSMALLREMOTEKEYCONTROLDISPLAYDVDMECHAMECHASLIDEDSP DIR8ch DAC ADCSWCOMPOSITERGBSWCOMPOSITESWAUDIOINPUT SELECTORBOXu-COMAM/FMTUNERSELECTOROUTPUTAUDIOPOWERAMPPREOUTSPOUTI/FAV OUTAV-INI/FLX-BUSI/FNAVII/FTVI/FRECEIVER(X16- )(X89- )(X34- )(X14- )(X35- ) Complete view4KVT-817DVD/827DVD/827DVDYKVT-837DVD/847DVD/867DVD X14-955/956to MECHA2DIN ONLY 1DIN ONLYfrom SYSCOMDRIVERMOTORIC107MOTORDRIVERIC1061DIN ONLYSDRAMIC852 IC850FROMIC800SH-31DIN ONLYGRAPHICIC700IC851SRAMSYSCOMGENERATORCLOCKIC64027MHzX'TALCHROMA GAMMA ICIC237IC2391H DELAYto X16to SH3DELAYD-FFto SYSCOM1DINONLYONLY2DINfrom SYSCOMto SUB PANEL2DIN ONLYIC101E2PROMIC104SYSCOMRESET ICIC105to ROM WRITERto BOX MCUSYNC SEPAIC830RGB SWIC2402DIN ONLYMPEGIC601 IC652ENCODERVIDEOIC650+DRIVER+MUTELPF+6dB AMPVIDEO SWIC654DECODERMECHAto DVDSDRAMIC560SYSCOMIC520FLASHCPLDIC470BUFFER2DIN ONLY2ch AUDIO DACIC402LPFIC400MUTEOPT DRIVER1DIN ONLYOPTOUTPOWER SUPPLYCONNECTORDC/DCTRANCEREG MPUSRAMDC/DCREGREGREGDC/DCREGREGREGto SYSCOM1DIN ONLYto X35to X34POWER SUPPLYSDRAMIC750SDRAMIC751DIVIDINGFREQUENCY1.52 FREQUENCYDIVIDINGLCD CSLCD CONTROLLCD DATALCD CLKSRCRESETKEY CONTROLKEY2EJECTREMOLED R,G,BTMOTOR MTMOTOR PSMOTOR MSMOTOR PRL M+RL M- EX M-EX M+D(15:0) A(19:1) A(22:1) D(15:0)A(24:1)D(31:0)A(12:4) D(31:0)SH CLKSH MREQSH SREQSH MDATASH SDATASH RESETSH CONSH STBYSH INISH DACKGR INTGR REQTOUCHTOUCH EN13.5MHz 36.864MHzPLL CLKPLL ONDCLK 9.6MHzRGBVCOMPOLSGRAPHIC RGBR-Y B-Y4.43MHz3.58MHzBLKT/C HD T/C VDHSYVSYVMUTEYDATAX0X1Y0XDATAG-VDG-HDCKNAVILKEY3SRCKEY4EJECTREMOAUTO DIMMERPH DETR SENSSW A,B,CKEY1OPEN/CLOSESW D MODE1,2,3LCD PONNTSC PALPWMMIRRORHPOSI1,2,3,4,LED GLED RSDASCLM CLKFROM VPPS DATAM DATARESETM DATAS REQM REQM CLKS DATASYS ONVDHDCPNTSC PALTV/NAVI RGCOMPOSITERGBCCIR601(7:0)VCLOCKVSYNCHSYNCDVDRGBDVDCOMP V DVDCOMP VMUTERGB SW VIDEO27MHz27MHzATAPI I/FD(15:0)A(11:1)BE RSTBE CLKBE MREQBE SREQBE MDATABE SDATAA(21:0) D(7:0)LD(3:0)LA(1:0)LA17SPDIFDATA1BCLKLRCLKMCLKAUDIODOWNMIXADACMLADACMCADACMDADACRST+14.4VPON+8.5V-7V+7V+14.4VBU3.3VPON+14.4V+7.5VSW5VV5VMECHA5V+14.4VPON SW3.3VSW2V1.8V1.9VGCDACC+BPRK DETREMOILLUMIREV DETACC DETDVDRGB27MHzCDEACCGCD+BMD(15:0)MA(13:0)MA(13:0)MD(31:16)/956)(X14-955BLOCK DIAGRAMKVT-817DVD/827DVD/827DVDYKVT-837DVD/847DVD/867DVD5BLOCK DIAGRAMX34-355/381LX I/FNV I/Fto TV TUNto X14ISO AMPIC500ISO AMPIC405IC413AUDIOIC414SELSELAUDIOR SWIC400-402G SWB SWSELVIDEOIC416VIDEOSELIC406IC415SELVIDEO6dB AMPVIDEO SELIC40875 DRIVERDRIVER6dB AMPVIDEO SEL75IC407SELVIDEOIC404FM AM F/EFSTBUFFRDSIC251DECODERADJUSTLEVELMUTEMUTEADJUSTLEVELMUTEADJUSTLEVELIC151ADJUSTLEVELTONEEQADC(2ch)IC7MUTEDIR SELIC10DSPIC9S/P DIFDAC(8ch)IC6BASSMANAGEMENTIC12LPFIC2-4REGREGREG REGPOWERAMPIC100DCMUTE AMPIC200-202 PRE OUTAV OUTMUTEAV IN1ISO AMPIC204AV IN2ISO AMPIC203R-CAMSEPIC403SYNCMCUIC303 SW REGREGREGREG REGREG SWLX CONLX CLKLX DATA MLX DATA SLX REQ SLX MUTELX RSTLX REQ MAUD LchAUD RchA GNDREMOSYNCGA GNDRAUD LchAUD RchTXRXBTV DATA MTV DATA STV REQ STV REQ MCOMP VBM RSTRGTV CLKTV CONTV RchA GNDTV LchCOMP VDVD RchDVD LchA GNDBGRM REQ SM REQ MM DATA SM DATA MM RSTM CLKM CONREMO8MCU322MCU3336MCU36MCU3DVD COMP3MCU2MCU2MCU1MCU2MCUMCU2MCU1MCU2MCU2RDDARDCLQUALMPX for RDSMCUS-METERIF COUNTSDASCLRDS MUTEQUALITY4MCUPON AMA OUT3MCUACIN0(FRONT)ACIN1(REAR)FRONTHPF(FRONT) (FRONT)MUTE VOL(FRONT)(SUB-W)ACIN2RACIN2L(CENTER)MUTE(REAR)REAR(REAR)HPF VOL(REAR)SUBMAIN2ZONE2ZONE(CENMUTE/NF L(NF)LPFVOLCENTERSUB-W SUB) SUB)(CEN(FRONT)PAOUT0(REAR)PAOUT1LDOUT1(REAR)LDOUT0(FRONT)(CEN/NF)LDOUT2L(SUB/NF)LDOUT2ROUTPUT SELTUNEAUXCDCHCDMDMAININPUT SELSUBAUXVOL INSCLSDAS-MUTEDCERRMCU45VDSPA8VDSPD5V3.3V1.25V3.3V4MCUSVRBEEPMUTESTBYRR+ -RL+ -FR+ -FL+ -IC2VIP.
