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.

SERVICE NOTE

CAUTION

Use of controls or adjustments or performance of proce-

dures other than those specified herein may result in haz-

ardous radiation exposure.

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.

NOTES ON HANDLING THE 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, ob-

serve from more than 30 cm away from the objective lens.

NOTES ON PICK-UP FLEXIBLE BOARD

The pick-up flexible board in this set is secured to the optical pick-

up with an adhesive tape. Once the tape is removed, an adhering

force becomes weak, and it cannot be reused.

Therefore, if the optical pick-up is replaced, replace also the pick-

up flexible board with a new one.

– main board (side B) –

NOTEFOR REPLACEMENT OF COMPLETE MAIN BOARD

The complete MAIN board (A-3294-762-A) of this set can be set to

address the specification for each destination by shorting or open-

ing one solder bridge of the MAIN board on theAEP and UK mod-

els and German models :

AEP and UK models : short

German model : open

The solder bridge below shold be opened when replacing the com-

plete MAIN board on the German model.

Display

FM Auto Scan/Stop Level Adjustment

Setting :

D-BASS switch : OFF

SOURCE button : FM

3. Push the preset 3 button.

Display

TUNER SECTION 0 dB = 1 µV

Cautions during repair

When the tuner unit is defective, replace it by a new one

because its internal block is difficult to repair.

TEST MODE

This set have the test mode function. In the test mode, FM Auto

Scan/Stop Level and MW Auto Scan/Stop Level adjustments can

be performed easier than it in ordinary procedure.

1. Set the “OFF” mode.

2. Push the preset 4 button.

3. Push the preset 5 button.

4. Press the preset 1 button for more than two seconds.

5. Then the display indicates all lights, the test mode is set.

1. Push the OFF button.

Note on Adjustment

The adjustments of tuner section, should be performed according

to the following sequence.

1. FM Auto Scan/Stop Level Adjustment

2. FM Stereo Separation Adjustment

3. FM RDS S-Meter Adjustment

4. MW Auto Scan/Stop Level Adjustment

4. Adjust with the volume RV2 on TU601 so that the “FM”

indication turns to “FM0” indication on the display window.

But, in case of already indicated “FM0”, turn the RV2 so that

put out light “0” indication and adjustment.

CD SECTION

Note:

1. CD Block basically constructed to operate without adjustment.

Therefore, check each item in order given.

2. UseYEDS-18 disc (3-702-101-01) unless otherwise indicated.

3. Use the oscilloscope with more than 10 MΩimpedance.

4. Clean an objective lens by an applicator with neutral detergent

when the signal level is low than specified valuewiththefollowing

checks.

Focus Bias Adjustment

Setting: This adjustment is performed with the set placed

horizontally.

Focus Gain Adjustment (Coarse adjustment)

Thisadjustment isnot requiredunlessthe followingparts arereplaced:

• Optical pick-up

•RV4

Procedure:

1. Set RV4 to the standard position. (mechanical center)

2. Check whether operation noise (while noise type) caused by

the 2-axis device (lens section of the optical pick-up) is

abnormally loud.

If the operation noise is too loud, turn RV4 slightly counter-

clockwise.

• If the gain is too low:

Focus does not function and no music is selected.

• If the gain is too high:

Noise caused by scratches and dust is heard and the operation

becomes unstable.

Adjustment Location: servo board

Adjustment Location: servo board (component side)

Procedure:

1. Connect an oscilloscope between TP (RF) and TP (RF. GND)

on the SERVO board.

2. Connect the power supply.

3. Push the RESET button (S900) on the MAIN board.

4. Insert the disc (YEDS-18) and playback.

5. Adjust RV1 so thatthe oscilloscope waveformis clear andcheck

RF signal level is correct or not.

Note: Clear RF signal waveform means that the sharp “≈” can be

clearly distinguished at the center of the waveform.

• When observing the eye pattern, set the oscilloscope toAC range

and raise the vertical sensitivity so that it may be easily seen.
