Design and specifications are subject to change without notice.
After correcting the original service problem, perform the followingsafety checks before releasing the set to the customer:Check the antenna terminals, metal trim, “metallized” knobs, screws,and all other exposed metal parts for AC leakage. Check leakage asdescribed below.
LEAKAGEThe AC leakage from any exposed metal part to earth ground andfrom all exposed metal parts to any exposed metal part having areturn to chassis, must not exceed 0.5 mA (500 microamperes).Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCAWT-540A. Follow the manufacturers’ instructions to use theseinstruments.
2. A battery-operated AC milliammeter. The Data Precision 245digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of aVOM or battery-operated AC voltmeter. The “limit” indicationis 0.75 V, so analog meters must have an accurate low-voltagescale. The Simpson 250 and Sanwa SH-63Trd are examplesof a passive VOM that is suitable. Nearly all battery operateddigital multimeters that have a 2V AC range are suitable. (SeeFig. A)

Notes on chip component replacement• Never reuse a disconnected chip component.• Notice that the minus side of a tantalum capacitor may be
damaged by heat.
Flexible Circuit Board Repairing• Keep the temperature of 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.
CAUTIONUse of controls or adjustments or performance of proceduresother than those specified herein may result in hazardousradiation exposure.
This appliance is classified asa CLASS 1 LASER product.This label is located on the rearexterior.
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.

SERVICING NOTES
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCKOR BASE UNIT
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 CHECK
The 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, observefrom more than 30 cm away from the objective lens.
LASER DIODE AND FOCUS SEARCH OPERATION CHECK
Carry out the “S curve check” in “CD section adjustment” and checkthat the S curve waveform is output several times.

1. Demagnetize the record/playback head with a headdemagnetizer.
2. Do not use a magnetized screwdriver for the adjustments.3. After the adjustments, apply suitable locking compound to the
parts adjust.4. The adjustments should be performed with the rated power
supply voltage unless otherwise noted.5. The adjustments should be performed in the order given in
this service manual. (As a general rule, playback circuitadjustment should be completed before performing recordingcircuit adjustment.)
6. The adjustments should be performed for both L-CH and R-CH.
7. Switches and controls should be set as follows unless otherwisespecified.

CD SECTION
Note:1. CD Block is basically designed to operate without adjustment.
Therefore, check each item in order given.2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated.3. Use an oscilloscope with more than 10MW impedance.4. Clean the object lens by an applicator with neutral detergent
when the signal level is low than specified value with thefollowing checks.
S-curve CheckConnection:
Procedure:1. Connect an oscilloscope to test point TPO102 (FE1) and TP
117(VC) on the CD board.2. Turn the power on.3. Put the disc (YEDS-18) in and turned power switch on again
and actuate the focus search. (actuate the focus search whendisc table is moving in and out)
4. Check the oscilloscope waveform (S-curve) is symmetricalbetween A and B. And confirm peak to peak level within 2.4± 1 Vp-p.
S-curve waveform
Note:• Try to measure several times to make sure than the ratio
of A : B or B : A is more than 10 : 7.• Take sweep time as long as possible and light up the
brightness to obtain best waveform.

Procedure:1. Connect an oscilloscope to test point TP124 (RFAC) and TP
117(VC) on the CD board.2. Turn the power on.3. Put the disc (YEDS-18) in to playback the number five track.4. Confirm that oscilloscope waveform is clear and check RFAC
signal level is correct or not.Note: A clear RFAC signal waveform means that the shape “◊” can be
clearly distinguished at the center of the waveform.

E-F Balance CheckConnection:
Procedure:1. Connect an oscilloscpe to test point TPO103 (TE1) and TP117
(VC) on the CD board.2. Turn the power on.3. Select the function “CD”.
4. Press three buttons of [ENTER], M , and[SURRUUND MODE] simultaneously to set the CD servicemode.
5. Put the disc (YEDS-18) in to playback the number five track. 6. Press the . button. The message “TRAVERSE” is
displayed. (The tracking servo and the sledding servo areturned OFF)
7. 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 ± 22%
Traverse Waveform
8. Press the . button. The message “TRAVERSE” isdisplayed. (The tracking servo and sledding servo are turnedON)Confirm the C (DC voltage) is almost equal to the A (DCvoltage) is step 5.
9. To exit from this mode, perform as follows.1) Move the optical pick-up to the most inside track.
2) Press three buttons of x , [CLEAR], and [DISPLAY]
simultaneously. (cold reset)Notes:
• Always move the optical pick-up to most inside trackwhen exiting from this mode. Otherwise, a disc will notbe unloaded.
• Do not run the sled motor excessively, otherwise the gearcan be chipped.
