ELECTRICAL PARTS LIST. 30This appliance is classifiedas a CLASS 1 LASERproduct.The CLASS 1 LASERPRODUCT MARKING islocated on the rear exterior.CAUTIONUse of controls or adjustments or performance of proce-dures other than those specified herein may result in haz-ardous radiation exposure.Notes on Chip Component Replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be dam-aged by heat.NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK ORBASE UNITThe laser diode in the optical pick-up block may suffer electrostaticbreakdown because of the potential difference generated by thecharged electrostatic load, etc. on clothing and the human body.During repair, pay attention to electrostatic breakdown and also usethe procedure in the printed matter which is included in the repairparts.The flexible board is easily damaged and should be handled withcare.NOTES ON LASER DIODE EMISSION CHECKThe laser beam on this model is concentrated so as to be focused onthe disc reflective surface by the objective lens in the optical pick-upblock. Therefore, when checking the laser diode emission, observefrom more than 30 cm away from the objective lens.RadioFans.CN 收音机爱 好者资料库 3 FL tube/ KEY check modeAfter to enter the power on, when p button, TIME button and) button are pressed at the same time, you will be check FLtube.Whenever press the above mentioned three buttons at the sametime, change to check mode of FL tube.Under check mode of FL tube when any pressing button or turn= AMS + button, change to KEY check mode.To finish KEY check mode, press the above mentioned threebuttons at the same time.All FL tube indicator light onA segment pattern mode 1A segment pattern mode 2Finish the test modeNote 1)All FL tube light on mode is kept when three buttons which ispressed to enter all FL tube light on mode, release at the same time.If you will be release failure them, it is moved to KEY check modeafter all FL tube light on mode.Note 2)Under KEY check mode, every time and button pressed or = AMS + button turned on, figure on “ KEY= ” of FL tubeis increased. How to operate with a single unitNormally this set does not operate with a single unit.When you must be mending, connect to other unit.If the SYSTEM POWER switch of the amplifire is set to ON, thepower supply of the set is turned on.In case of other unit is nothing, the service box (PFJ-1) andexclusive jig (J-2501-078-A) are necessary to operate the set witha single unit.In case of above mentioned, press the p button and TIME buttonat the same time, to enter the power on.SECTION 1SERVICE NOTEnnn(Press three buttons at the same time)(Press three buttons at the same time)(Press three buttons at the same time)KEY check mode(Any pressing button or turn = AMS + button.9(Press three buttons at the same time)SERVICE BOX (PFJ-1)POWER SWFH-E939, 838, 737CDP/TCCN90417PCN9027PCORD WITH CONNECTOR 17P(attached to PFJ-1)JIG(J-2501-078-A)CORD WITH CONNECTOR 7P(attached to set)SETCN301 7PSYSTEM CONTROL 4 SECTION 2GENERALFront PanelDisplay WindowSECTION 3DISASSEMBLYNote : Follow the disassembly procedure in the numerical order given.3-1.

Therefore, checkeach item in order given.2.Use YEDS-18 disc (3-702-101-01) unless otherwise indicated.3.Use an oscilloscope with more than 10M impedance.4.Clean the objective lens by an applicator with neutral detergentwhen the signal level is low than specified value with the followingchecks.5.Adjust the focus bias adjustment when optical block is replaced.Focus Bias AdjustmentSECTION 4ELECTRICAL ADJUSTMENTSProcedure:1.Connect oscilloscope to test point TP (RF). (GND terminal : VC)2.Turn Power switch on.3.Put disc (YEDS-18) in and playback.4.Adjust RV101 so that the waveform is clear.(Clear RF signal waveform means that the shape “ ” can beclearly distinguished at the center of the waveform.)5.After adjustment, check the RF signal level. RF signalVOLT/DIV : 200 mVTIME/DIV : 500 nSS Curve CheckProcedure:1.Connect oscilloscope to test point TP(FEO).2.Connect between test point TP(FOK)and GND by lead wire.3.Turn Power switch on.4.Put disc (YEDS-18) in and turnd Power switch on again andactuate the focus search. (In case of using SERVICE BOX actuatethe focus search when disc table is moving in and out.)5.Check the oscillosope waveform (S-curve) is symmetrical betweenA and B. And confirm peak to peak level within 2.40.7 Vp-p.S-curve waveform6.After check, remove the lead wire connected in step 2.Note : Try to measure several times to make sure than the ratio ofA:B or B:A is more than 10:7. Take sweep time as long as possible and light up thebrightness to obtain best waveform.RF Level CheckProcedure:1.Connect oscilloscope to test point TP (RF) on BD board.2.Turn Power switch on.3.Put disc (YEDS-18) in and playback.4.Confirm that oscilloscope waveform is clear and check RF signallevel is correct or not.Note :Clear RF signal waveform means that the shape “ ” can be clearlydistinguished at the center of the waveform.RF signal waveformBD boardoscilloscopeTP (FEO)TP (FOK)VOLT/DIV : 200mVTIME/DIV : 500nSlevel : 1.30.3 Vp-pBD boardTP (RF)TP (VC)oscilloscopeBD boardTP (RF)VCoscilloscope(DC range)level1.30.3 Vp-psymmetrywithin 2.40.7 Vp-pAB 7 E-F Balance CheckProcedure:1.Connect oscilloscpe to test point TP (TEO).2.Turn Power switch on.3.Connect pin of IC60I on the PANEL board to GND with a leadwire.4.Put disc (YEDS-18) in and playback.5.Push TIME button.6.Confirm that the oscilloscope waveform is symmetrical on the topand bottom in relation to 0Vdc, and check this level.
