SERVICING NOTES

SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITHMARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTSLIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESECOMPONENTS WITH SONY PARTS WHOSE PART NUMBERSAPPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTSPUBLISHED BY SONY.

CAUTIONUse of controls or adjustments or performance of proceduresother than those specified herein may result in hazardousradiation exposure.

This appliance is classified as a CLASS 1 LASER product.The CLASS 1 LASER PRODUCT MARKING is located onthe exterior.

Laser component in this product is capable of emitting radiationexceeding the limit for Class 1.

The laser diode in the optical pick-up block may suffer electrostaticbreak-down because of the potential difference generated by thecharged electrostatic load, etc. on clothing and the human body.During repair, pay attention to electrostatic break-down and alsouse the procedure in the printed matter which is included in therepair parts.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-up block. Therefore, when checking the laser diode emission,observe from more than 30 cm away from the objective lens.

LASER DIODE AND FOCUS SEARCH OPERATIONCHECKCarry out the “S curve check” in “CD section adjustment” and checkthat the S curve waveforms is output three times.

NOTES ON HANDLING THE OPTICAL PICK-UPBLOCK OR BASE UNIT

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.

Flexible Circuit Board Repairing• Keep the temperature of the soldering iron around 270 ˚C during

repairing.• Do not touch the soldering iron on the same conductor of the

circuit board (within 3 times).• Be careful not to apply force on the conductor when soldering or

unsoldering.

Unleaded solderBoards requiring use of unleaded solder are printed with the lead-free mark (LF) indicating the solder contains no lead.(Caution: Some printed circuit boards may not come printed withthe lead free mark due to their particular size.)

: LEAD FREE MARKUnleaded solder has the following characteristics.• Unleaded solder melts at a temperature about 40°C higher than

ordinary solder.Ordinary soldering irons can be used but the iron tip has to beapplied to the solder joint for a slightly longer time.Soldering irons using a temperature regulator should be set toabout 350°C.Caution: The printed pattern (copper foil) may peel away if theheated tip is applied for too long, so be careful!

• Strong viscosityUnleaded solder is more viscous (sticky, less prone to flow) thanordinary solder so use caution not to let solder bridges occur suchas on IC pins, etc.

• Usable with ordinary solderIt is best to use only unleaded solder but unleaded solder mayalso be added to ordinary solder.

back, the tracking servo is switched on or off for checkingtracking balance. (see page 17)

6. To exit from this mode, press the [POWER] button or discon-nect the power cord.

[TC Test Mode]Procedure:1. Extract an AC plug.2. While depressing the TAPE Y button, insert an AC plug.3. The message “TC TEST” is displayed and TC test mode is

activated.* Zero Return1. Press the + > M or – .m button.2. The tape is rewound to the counter zero position.* Automatic record/playback test1. Press the REC START/REC PAUSE button.2. The message “AUX” is displayed and AUX input is selected.3. The tape is rewound to the counter zero position and record-

ing is started automatically.4. When the x button is pressed, the tape is rewound to the

recording stated point and the set starts playback.5. To exit from this mode, press the [POWER] button or discon-

nect the power cord.

exiting from this mode. Otherwise, a disc will not be unloaded.• Do not run the sled motor excessively, otherwise the gear can

be chipped.

E-F Balance AdjustmentConnection:

Procedure:1. Connect an oscilloscpe to test point TP4 (TE) and TP7 (VC)

on the BD board.2. While depressing the CD u button, insert an AC plug to

enter the CD test mode.3. Put the disc (YEDS-18) in to playback the number five track.4. Press the button. If it plays, press the CD u

again. (The tracking servo and the sledding servo areturned OFF)

5. Check the level B of the oscilliscope's waveform and the A(DC voltage) of the center of the Traverse waveform.Confirm the following :A/B x 100 = less than ± 10%

THIS NOTE IS COMMON FOR PRINTED WIRINGBOARDS AND SCHEMATIC DIAGRAMS.(In addition to this, the necessary note is printedin each block.)

For schematic diagrams.Note:• All capacitors are in µF unless otherwise noted. pF: µµF

50 WV or less are not indicated except for electrolyticsand tantalums.

• All resistors are in Ω and 1/4 W or less unless otherwise

specified.• f : internal component.• 2 : nonflammable resistor.• 1 : fusible resistor.• C : panel designation.

For printed wiring boards.Note:• X : parts extracted from the component side.• Y : parts extracted from the conductor side.• f : internal component.• : Pattern from the side which enables seeing.

• A : B+ Line.• B : B– Line.• Voltages are taken with a VOM (Input impedance 10 MΩ).

Voltage variations may be noted due to normal produc-tion tolerances.

• Waveforms are taken with a oscilloscope.Voltage variations may be noted due to normal produc-tion tolerances.

• Circled numbers refer to waveforms.• Signal path.

F : TUNERJ : CDd : AUXE : PB (TAPE)a : REC (TAPE)

Note: The components identified by mark 0 or dotted linewith mark 0 are critical for safety.Replace only with part number specified.

NOTE:• Due to standardization, replacements in the

parts list may be different from the partsspecified in the diagrams or the componentsused on the set.

• -XX, -X mean standardized parts, so they mayhave some difference from the original one.

• Items marked “*” are not stocked since theyare seldom required for routine service. Somedelay should be anticipated when ordering theseitems.

• CAPACITORS:uF: µF

• RESISTORSAll resistors are in ohms.METAL: metal-film resistorMETAL OXIDE: Metal Oxide-film resistorF: nonflammable

• COILSuH: µH The components identified by mark 0 or

dotted line with mark 0 are critical for safety.Replace only with part number specified.

• SEMICONDUCTORSIn each case, u: µ, for example:uA...: µA... , uPA... , µPA... ,uPB... , µPB... , uPC... , µPC... ,uPD..., µPD...

When indicating parts by reference number,please include the board name.
