Note : During the EEPROM initialization the keys may not be operated.Press the “POWER“ key to initiate the STAND-BY mode and the test mode will then be cancelled.Adjustment and confirmation matter1.The oscilloscope is connected between “1“(RFOP) ofCN104 and “2“(GND).2.Reproduction of the test disc (VT-501)made by JVC.3.It is confirmed that RF LEVEL is 350mVp-p 150mVp-p.4.When there is disorder in the waveform road cuts etc,test disk is exchanged and measured.1. The CD jitter meter is connected between “11“(GND)of CN104 and “12“(FLTOUT).The RF level is observed at the same time.2.The first test disk(CTS-1000) made of JVC is reproduced.3.It is confirmed that RF LEVEL is 360 100mVp-p.5. When there is disorder in the waveform road cutsetc, test disk is exchanged and measured.FRONT SIDEP12andGNDP1andGNDMain AdjustmentDVD SERVO CONTROL PWBTH-A10R/TH-A101-22Measurement Adjustment point Refer to Fig.2ModeReproduction partDiscMeasurement machine No need “Flap adjustment“ of the Pick-up guide shaft adjusts“Tangential adjustment machine screw“ A and“Tilt adjustment machine screw“ B from the DVD Mechanism A'ssy bottom. 1.

After the tray open/close procedure has completed, unplug it again and then perform the initialization procedure again.3) Press the “OPEN/CLOSE“ key of the main unit to draw the tray out.*Place the test disk (VT-501) on the tray and then press the “OPEN/CLOSE“ key.(Note: Pushing the tray to close it is not possible.)4) Press the “PLAY“ key of the main unit.5) The “JIT 0000“ is displayed on the FL indicator. Set the FL indicator figure value to its minimum by adjusting the pickup guide shaft flap.* The test mode is cancelled when the power is turned off.TH-A10R/TH-A101-23Confirmation after adjustment.Confirm to reproduce video CD and CD afterthe DVD test disc is adjusted and to find abnormality. (5) About keeping the disc As for the DVD test disc, plane accuracy is demanded.Please note the keeping place on the disc. 1. Please do not put the disc directly on the work desk etc. after uses . 2. To keep the planarity of the disc, politely handle ,and please put in a special case and keepthe disc vertically after uses . Please keep keeping the disc in a cool place where direct sunshine and the air-conditioning wind do not drive. 3. When the disc curves,an accurate adjustment cannot be done. Please exchange for a new test disc and adjust optics. 4. Other discs might not be able to be reproduced when adjusting on a curved disc. AABFig.2Point of adjustment * Please execute the static electricity protection measures before starting the adjustment.* When the following parts are exchanged,optical adjustment “Adjust the flap of the disc motor“ is necessary.1.The disc motor was exchanged.2.The laser pick up was exchanged.3.The traverse motor unit was exchanged. NoteAdditionally, please adjust the flap of the disc motor when the picture quality deterioration is seen .The basic adjustment though, is unnecessary for part exchange in the traverse.An optical adjustment in the laser pick up cannot be done.Please adjust the flap of the disc motor after exchanging the laser pick up.* When the traverse unit is exchanged, the adjustment is basically unnecessary. 2-1TH-A10R/TH-A10LOADINGMOTORFEP(Front End Processor)IC101AN8706FHQSPINDLE DRIVERIC251AN8485SB4CH DRIVERIC271BA5983FMCRYSTALX40113.5MHzODC(Optical Disc Controller)IC301MN103007BGADSC(Digital ServoController)IC201MN67705EAOSC X37133.86MHzIC371,IC372 TC7SH04FUUNIT CPUIC401MN102L25GCX16M ROMIC402MSM531622F67GIC374TC7WH74FU-XVIDEO ENCODERIC554MC44724AVFU+2.5 REG.IC555MC33269D2M FRAMIC552UPD42280GU-30(MN4777AS-XE)GRAPHIC CONTROLLERIC551JCE80118M ROMIC553MSM531622F69GAVDECODERIC501ZIVA3-PA116M SDRAMIC504D4516161AG5-A10(KM416S1020CTG10)(MN4SV17160BT-10)16M SDRAMIC505D4516161AG5-A10(KM416S1020CTG10)(MN4SV17160BT-10)OPEN/CLOSE SW.OSC.27MHZIC502NAXO265-001XIC507TC7WH74FULDLDTE14, FE1, 2TRVSW H1+/-, H2+/-,H3+/-STMA, BSTMNA, BSDM13T+, T-F+, F-91, 92 9496T+/-F+/-TRVSWSWOPEN / SWCLOSE47502713, 2820, 21 22, 26,2825, 27 11, 12 13, 1411151812,13 35, 38 35, 38 59, 6016233610, 11163,172,17381124,695100 15,271 8177 178 206159581551313925FWD 07 FRD 07CA 019 CD 072, 3, 6, 7412, 1414, 99 3946 51, 525071, 7611891, 93 111 18,1970,729,10231179, 209, 104,10523, 2668161084510027CLK169 43151149ERRORSIGNALSCONTROLSTATESCPSCK SDOUTFGST/SPFCFMA +/- FMB +/-M +/-CONTROLSIGNALSTOPENTCLOSEW A ITDECW A IT ODCSTREAM D A T AS .
