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.
This appliance is classified as a CLASS 1 LASER product. TheCLASS 1 LASER PRODUCT MARKING is located on the rearexterior.
CAUTIONUse of controls or adjustments or performance of proceduresother than those specified herein may result in hazardous radiationexposure.
Laser component in this product is capable of emitting radiationexceeding the limit for Class 1.
SAFETY CHECK-OUT(US model only)
After correcting the original service problem, perform thefollowing safety 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.
LEAKAGE
The 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 microampers).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 examples ofa passive VOM that is suitable. Nearly all battery operateddigital multimeters that have a 2V AC range are suitable. (SeeFig. A)

SERVICING NOTES
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 OPERATIONCHECK
Carry out the “S curve check” in “CD section adjustment” and checkthat the S curve waveform is output repeatedly.
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 damaged
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.

When a general remote commander is used:1. Press the @/1 button to turn ON the power.2. Open the front cover, and press the CD PLUS ONE button.3. Set the disc (YEDS-18) into the “PLUS ONE” slit.4. Close the front cover, and chuck the disc.5. Press the @/1 button to turn OFF the power.6. Connect the oscilloscope to TP (TE) of the BD board.7. Connect TP (ADJ) of the MAIN board and connect TP (GND)
with a lead wire.8. Press the @/1 button to turn ON the power.9. Playback the fifth track of the disc.10. Press the 3 button on the remote commander. (The tracking
servo and the sledding servo are turned OFF.)11. Check the level B of the oscilloscope's waveform and the A
(DC voltage) of the center of the Traverse waveform.Confirm the following :A/B x 100 = less than ± 10%
10. Confirm that oscilloscope waveform is clear and check RF sig-nal level is correct or not.
11. Turn OFF the power, and remove the lead wire connected atstep 7.
Note : A clear RF signal waveform means that the shape “◊” can beclearly distinguished at the center of the waveform.
E-F Balance (Traverse) CheckThe procedure for this checking method differs for when a generalremote control unit is used and not used.
12. Press the 8 button on the remote control unit. (The trackingservo and sledding servo are turned ON.) Confirm the C (DCvoltage) is almost equal to the A (DC voltage) is step 11.
13. Turn OFF the power, and remove the lead wire connected atstep 7.
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 10 MW 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 CheckProcedure :1. Press the @/1 button to turn ON the power .2. Open the front cover, and press the CD PLUS ONE button.3. Set the disc (YEDS-18) into the “PLUS ONE” slit.4. Close the front cover, and chuck the disc.5. Press the @/1 button to turn OFF the power.6. Connect the oscilloscope to TP (FE) of the BD board.7. Connect TP (ADJ) of the MAIN board and connect TP (GND)
with a lead wire.8. Press the @/1 button to turn ON the power.9. The first track will be played back automatically. When the
CHECK button is pressed, “S JI” will be displayed on thefluorescent indicator tube, and focus search will be repeated.
10. Check the oscilloscope waveform (S-curve) is symmetricalbetween A and B. And confirm peak to peak level within 1.8 ±0.6 Vp-p.
11. Turn OFF the power, and remove the lead wire connected atstep 7.
Note : • Try to measure several times to make sure than the ratioof A : B or B : A is more than 10 : 7.
• Take sweep time as long as possible and light up thebrightness to obtain best waveform.
