2 CDS-9036zt 1. safety information this service manual is intended for qualified service technicians; it is not meant for the casual do-it-yourselfer. qualified technicians have the necessary test equipment and tools, and have been trained to properly and safely repair complex products such as those covered by this manual. improperly performed repairs can adversely affect the safety and reliability of the product and may void the warranty. if you are not qualified to perform the repair of this product properly and safely; you should not risk trying to do so and refer the repair to a qualified service technician. - cd player service precautions 1. for pickup unit(cxx1231) handling, please refer to"disassembly"(cx-597 service manual crt1829). during replacement, handling precautions shall be taken to prevent an electrostatic discharge(protection by a short pin). 2. during disassembly, be sure to turn the power off since an internal ic might be destroyed when a con- nector is plugged or unplugged. 3. please checking the grating after changing the ser- vice pickup unit(see page 31). 3 CDS-9036zt 7 5 3 2 6 10 9 4 8 1 2. exploded views and parts list 2.1 packing

------------------------- c 29 CDS-9036zt 1)precautions this unit uses a single power supply (+5v) for the reg- ulator. the signal reference potential, therefore, is connected to refo(approx. 2.5v) instead of gnd. if refo and gnd are connected to each other by mis- take during adjustments, not only will it be impossi- ble to measure the potential correctly, but the servo will malfunction and a severe shock will be applied to the pick-up. to avoid this, take special note of the fol- lowing. do not connect the negative probe of the measuring equipment to refo and gnd together. it is especially important not to connect the channel 1 negative probe of the oscilloscope to refo with the channel 2 negative probe connected to gnd. since the frame of the measuring instrument is usual- ly at the same potential as the negative probe, change the frame of the measuring instrument to floating sta- tus. if by accident refo comes in contact with gnd, immediately switch the regulator or power off. always make sure the regulator is off when connect- ing and disconnecting the various filters and wiring required for measurements. before proceeding to further adjustments and mea- surements after switching regulator on, let the player run for about one minute to allow the circuits to stabi- lize. since the protective systems in the unit's software are rendered inoperative in test mode, be very careful to avoid mechanical and /or electrical shocks to the sys- tem when making adjustment. disc detection during loading and eject operations is performed by means of a photo transistor in this unit.consequently, if the inside of the unit is exposed to a strong light source when the outer casing is removed for repairs or adjustment, the following mal- functions may occur. *during play, even if the eject button is pressed,the disc will not be ejected and the unit will remain in the play mode. *the unit will not load a disc. when the unit malfunctions this way, either re-posi- tion the light source, move the unit or cover the photo transistor. when loading and unloading discs during adjustment procedures, always wait for the disc to be properly clamped or ejected before pressing another key. otherwise, there is a risk of the actuator being destroyed. turn power off when pressing the button /ff or the button rev key for focus search in the test mode. (or else lens may stick and the actuator may be dam- aged.) 2)test mode the CDS-9036zt/es is used together with a cd con- trol unit(keh-m8276zt/x1n/es) to make adjustment. for adjustment, keys of the cd control unit are used. for your reference, how to enter test mode and oper- ate keys when using a cd control unit are shown be- low. the keys mentioned in the explanation of adjust- ment are of a cd control unit(keh-m8276zt/x1n/es). entering test mode short-circuit the probes indicated as "cd test" on the substrate of the CDS-9036zt/es, then set acc or back up to on. cancelling test mode set acc or back up to off. single/4trk/10trk/32trk will continue to operate even after the key is released.tracking is closed the moment c-move is released. jump mode resets to single as soon as power is switched off. 6. adjustment 6.1 cd cd test control unit(side a) short-circuit these two probes. 30 CDS-9036zt - flow chart rand cd carriage move or t. jump carriage move or t. jump scan scan track+ c rand track+ track- rpt rpt rpt rpt rpt track+ rand scan track+ track- track- track+ track- scan track+ rand track- track- 1- cd 1-99 cd 1-00 cd 1-91 cd 1-01 cd cd test acc, back-up on regulator off display cd player select regulator on display power on regulator on display during regulator off, press the scan key and the system will be put into the new test mode. *1 *1 display tracking close crg+ crg power off power off focus close *1 focus mode select power off tracking close tracking close auto adjustment display *4 display crg+ crg tracking balance adjustment tracking open agc *2 agc display select power off (in the case of continuous jumping) tracking open single 91(81) 10trk 93(83) 32trk 94(84) c.move 96(86) 4trk 92(82) 100trk 95(85) t.jump mode select display normal focus close 100 trk jump and carriage move normal display *1 s curve check focus eq check *2 focus gain track gain *3 00 01 02 tracking close in a little while the keys are released focus bias normal display *4 focus cancel tracking offset tracking balance spindle close : rough display (99) *3 test point short 31 CDS-9036zt ? note : unlike previous cd mechanism modules the grating angle of the pickup unit cannot be adjusted after the pickup unit is changed. the pickup unit in the cd mechanism module is adjusted on the production line to match the cd mechanism module and is thus the best adjusted pickup unit for the cd mechanism module. changing the pickup unit is thus best considered as a last resort. however, if the pickup unit must be changed, the grating should be checked using the procedure below. ? purpose : to check that the grating is within an acceptable range. ? symptoms of mal-adjustment : if the grating is off by a large amount symptoms such as being unable to close tracking, being unable to perform track search operations, or track searching taking a long time, may appear. ? method : ?measuring equipment ?oscilloscope, two l.p.f. ?measuring points ?e, f, refout ?disc ?abex tcd-784 ?mode ?test mode ? checking procedure 1. in test mode, load the disc and switch the 5v regulator on. 2. using the track+ and track- buttons, move the pickup unit to the innermost track. 3. press key rand to close focus, the display should read "91". press key track- to implement the tracking bal- ance adjustment the display should now read "8x". press key rand 4 times. the display will change, returning to "8x" on the fourth press. 4. as shown in the diagram above, monitor the lpf outputs using the oscilloscope and check that the phase differ- ence is within 75 . refer to the photographs supplied to determine the phase angle. 5. if the phase difference is determined to be greater than 75 try changing the pu unit to see if there is any improvement. if, after trying this a number of times, the grating angle does not become less than 75 then the mechanism should be judged to be at fault. ? note because of eccentricity in the disc and a slight misalignment of the clamping center the grating waveform may be seen to "wobble" ( the phase difference changes as the disc rotates). the angle specified above indicates the aver- age angle. ? hint reloading the disc changes the clamp position and may decrease the "wobble". 100k w 390pf 100k w 390pf e refout f refout xch ych oscilloscope l.p.f. l.p.f. control unit(s7) 6.2 checking the grating after changing the pickup unit 32 CDS-9036zt grating waveform ech ?
