This appliance is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT MARKING is located on the rear exterior.
This caution label is located inside the unit.
CAUTION
Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.
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.
SAFETY-RELATED COMPONENT WARNING !!
COMPONENTS IDENTIFIED BY MARK !OR DOTTED LINE WITH MARK !ON THE SCHEMATIC DIAGRAMS AND IN
THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.

SECTION 1
SERVICING NOTE
HOW TO OPEN THE DISC TRAY WHEN POWER SWITCH TURNS OFF
Insert a tapering driver into the aperture of the unit bottom, and turn in the direction of arrow.
* To close the disc table, turn the driver in the reverse direction.
CD-TEXTTEST DISC
This unit is able to display the text data (character information) written in the CD on its fluorescent indicator tube.
The CD-TEXT TEST DISC (TGCS-313: J-2501-126-A) is used for checking the display.
To check, perform the following procedure.
Procedure:
1.Turn ON the power and set the test disc.
2.Press the ” button and play back the disc.
3.The following will be displayed on the fluorescent indicator tube. Display : 1kHz/0 dB/ L&R
4.Rotate the AMS ± knob to switch the track. The text data of each track will be displayed.
Restrictions in CD-TEXT Contents and Display
The micro processor’s RAM has limit of capacity in this unit, The display may not show all the track titles in a disc when you play the CD TEXT TEST DISC, but it is not unusual. In that case, “NOT DISPLAY” appears in the display.
Pull out disc table
NOTES ON HANDLINGTHE OPTICAL PICK-UP BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic breakdown because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic breakdown and also use the procedure in the printed matter which is included in the repair parts.
The flexible board is easily damaged and should be handled with care.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused on the 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 OPERATION CHECK
Carry out the “S curve check” in “CD section adjustment” and check that the S curve waveform is output two times.

ELECTRICAL BLOCK CHECKING
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 the following checks.
S Curve Check
oscilloscope
BD board
TP (FE)
TP (VC)
Procedure :
1.Connect oscilloscope to test point TP (FE) on BD board.
2.Connect between test point TP (FEI) and TP (VC) by lead wire.
3.Turn Power switch on.
4.Put disc (YEDS-18) in and turn Power switch on again and actuate the focus search. (actuate the focus search when disc table is moving in and out.)
5.Check the oscilloscope waveform (S-curve) is symmetrical between A and B. And confirm peak to peak level within 3±1 Vp-p.

6. After check, remove the lead wire connected in step 2.
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.
