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.

CAUTION

Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

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

The following caution label is located inside the unit.

SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 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.

SERVICING NOTES

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT

The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic break-down 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 objectiv e lens.

LASER DIODE AND FOCUS SEARCH OPERATION CHECK

Carry out the “S curve check” in “CD section adjustment” and check that the S curve waveforms is output three times.

SECTION 4

TEST MODE

[MC Cold Reset]

• The cold reset clears all data including preset data stored in the

RAM to initial conditions. Execute this mode when returning the set to the customer.

Procedure:

1. Turn the power ON or set to the DEMO mode.

2. Press three buttons of [ /CLOCK SET], [ENTER/NEXT], and

?/1 simultaneously.

3. The set is reset, and displays “COLD RESET”, then becomes

DEMO mode.

[MC Hot Reset]

• This mode resets the set with the preset data kept stored in the

memory. The hot reset mode functions same as if the power cord is plugged in and out.

Procedure:

1. Turn the power ON or set to the DEMO mode.

2. Press three buttons of [ /CLOCK SET], [ENTER/NEXT],

and [DISC 1] simultaneously.

3. The set is reset, and becomes standby state.

[Change-over the AM Tuning Interval] (EXCEPT AEP, UK, and Saudi Arabia models)

• The AM tuning interval can be changed over 9 kHz or 10 kHz.

Procedure:

1. Press the ?/1 button to turn the power ON.

2. Select the function “TUNER”, and press the [TUNER/BAND]

button to select the BAND “AM”.

3. Press the ?/1 button to turn the power OFF.

4. Press the [ENTER/NEXT] and ?/1 buttons simultaneously,

and the display on the fluorescent indicator tube changes to “AM 9 K STEP” or “AM 10 K STEP”, and thus the tuning interval is changed over.

c

[CD Delivery Mode]

• This mode moves the optical pick-up to the position durable to vibration. Use this mode when returning the set to the customer after repair.

Procedure:

1. Press the ?/1 button to turn the power ON.

2. Press the [LOOP] and ?/1 buttons simultaneously.

3. A message “LOCK” is displayed on the fluorescent indicator

tube, and the CD delivery mode is set.

[LED and Fluorescent Indicator Tube All Lit, Key Check Mode]

Procedure:

1. Press three buttons of [ /CLOCK SET], [ENTER/NEXT],

and [DISC 2] simultaneously.

2. LEDs and fluorescent indicator tube are all turned on.

Press the [DISC 2] button, and the key check mode is activated.

3. In the key check mode, the fluorescent indicator tube displays

“K 0 J0 V0”. Each time a button is pressed, “K” value increases. However , once a button is pressed, it is no longer tak en into account. “J” value increases like 1, 2, 3 ... if turn the JOG dial clockwise, or it decreases like 0, 9, 8 ... if turn the JOG dial counterclockwise. “V” value increases like 1, 2, 3 ... if turn the [VOLUME] dial clockwise, or it decreases like 0, 9, 8 ... if turn the JOG dial counterclockwise.

4. To release from this mode, press three buttons in the same

manner as step 1, or disconnect the power cord.

[Aging Mode]

This mode can be used for operation check of tape deck section. Tape deck section work in parallel.

• If an error occurred: The aging operation stops and display then status.

• If no error occurs: The aging operation continues repeatedly.

Procedure:

1. Load the tapes into the decks A and B respectively.

2. Press the [FUNCTION] button to select the function “CD”.

3. Press the [PLAY MODE] button to set the “ ALL DISCS” mode,

and press the [REPEAT] button to “REPEAT” off.

4. Press three buttons of [ /CLOCK SET], [ENTER/NEXT],

c

and [DISC 4] simultaneously.

5. The aging mode is activ a ted, if the indicator of disc tray num-

ber on the fluorescent indicator tube is blinking.

6. To release from the aging mode, press the ?/1 button to turn

the power OFF and operate the cold reset. (Refer to the “MC Cold Reset”)

1. Display at the Aging Mode

• Display operating state of tape deck section alternately.

• If an error occurred, stop display.

2. Tape Deck Section

• The sequence during the aging mode is following as below.

• If an error occurred, stop display that step.

Precaution

1. Clean the following parts with a denatured alcohol-moistened swab:

record/playback heads pinch rollers erase head rubber belts capstan idlers

2. Demagnetize the record/playback head with a head demagnetizer.

3. Do not use a magnetized screwdriver for the adjustments.

4. After the adjustments, apply suitable locking compound to the parts adjusted.

5. The adjustments should be performed with the rated power supply voltage unless otherwise noted.

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 MΩ 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

Procedure:

1. Connect oscilloscope to TP (FE) and TP (VC).

2. Connect between TP (FE1) and TP (VC) by lead wire.

3. Connect between TP (A GCCON) and TP (GND) by lead wire.

4. Turn the power ON.

5. Load a disc (YEDS-18) and actuate the focus search. (In con-

sequence of open and close the disc tray, actuate the focus search)

6. Cofirm that the oscilloscope w aveform (S-curve) is symmetri-

cal between A and B. And confirm peak to peak level within 4 ± 1 Vp-p.

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.

4. Load a disc (YEDS-18) and press the H X button to play.

5. Confirm that the oscilloscope w aveform is clear and chec k RF signal level is correct or not.

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

Note: Clear RF signal waveform means that the shape “◊” can be clearly

distinguished at the center of the waveform.

Note on Printed Wiring Board:

• X : parts extracted from the component side.

• Y : parts extracted from the conductor side.

• : Pattern from the side which enables seeing. (The other layers' patterns are not indicated.)

Caution: Pattern face side: Parts on the pattern face side seen from (Side B) the pattern face are indicated. Parts face side: Parts on the parts face side seen from (Side A) the parts face are indicated.

• Indication of transistor.

Note on Schematic Diagram:

• All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or less are not indicated except for electrolytics and tantalums.

• All resistors are in Ω and 1/ specified.

• 2 : nonflammable resistor.

• 5 : fusible resistor.

• C : panel designation.

Note: The components identified by mark 0 or dotted line

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

• A : B+ Line.

• B : B– Line.

• H : adjustment for repair.

• Voltages are taken with a VOM (Input impedance 10 MΩ).

Voltage variations may be noted due to normal production tolerances.

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

• Circled numbers refer to waveforms.

• Signal path.
