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.

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.

SAFETY CHECK-OUT

After correcting the original service problem, perform the following safety check 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 as described below.

LEAKAGE TEST

The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return 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 RCA WT-540A. Follow the manufacturers’ instructions to use these instruments.

2. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job.

3. Measuring the voltage drop across a resistor by means of a V OM or battery-operated A C voltmeter . The “limit” indica tion is 0.75 V, so analog meters must have an accurate low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive V OM that is suitable. Nearly all battery operated digital multimeters that have a 2 V A C range are suitable. (See Fig. A)

Laser component in this product is capable of emitting radiation exceeding the limit for Class 1.

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 .

ATTENTION AU COMPOSANT AYANT RAPPORT

À LA SÉCURITÉ! LES COMPOSANTS IDENTIFÉS P AR UNE MARQUE 0 SUR LES DIAGRAMMES SCHÉMA TIQUES ET LA LISTE DES PIÈCES SONT CRITIQUES POUR LA SÉCURITÉ DE FONCTIONNEMENT. NE REMPLACER CES COMPOSANTS QUE PAR DES PIÈSES SONY DONT LES NUMÉROS SONT DONNÉS DANS CE MANUEL OU DANS LES SUPPÉMENTS PUBLIÉS PAR 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 pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.

[CD Ship 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 set ON.

2. Press three buttons x (TAPE A), x (CD), and Z (CD1)

simultaneously.

3. After the “STANDBY” display blinks six times, a message

“LOCK” is displayed on the liquid crystal display, and the CD ship mode is set.

[GC Test Mode]

•This mode is used to check the software version, liquid crystal display and keyboard.

Procedure:

1. Press three buttons x (TAPE A), x (CD) and ?/1 simul-

taneously.

2. Segments of the liquid crystal display are all turned on.

3. When you want to enter the software version display mode,

press the CD 1 button . The model number and destination are displayed.

4. Each time the CD 1 button is pressed, the display changes

starting from MC version, GC version, CD version, CDD version, CDMA version, CDMB version, BDA version, BDB version , ST version, TA version, TM version, TC version and MD version in this order.

5. Press the CD 2 button, and the key check mode is activated.

6. In the key check mode, “K 0 J 0 V 0” is displayed. Each time

a button is pressed, “K 0” value increases. However, once a button is pressed, it is no longer taken into account. “V 0” value increases like 1, 2, 3 ... if rotating the VOLUME knob clockwise, or it decreases like 0, 9, 8 ... if rotating counterclockwise. “J0” value increases if rotating the FUNCTION , BASS or TREBLE knob clockwise, or it decreases if rotating counterclockwise.

7. T o e xit from this mode, press three b uttons in the same manner

as step 1, or disconnect the power cord.

[CD Ship (Memory Clear) Mode]

• Set the CD ship mode and set the default setup when shipped from the factory at the next AC power on.

Procedure:

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

2. Select the function “CD ”.

3. Press three buttons x (TAPE A), x (CD), and Z (CD1)

simultaneously.

4. After the “STANDBY” display blinks six times, a message

“LOCK” is displayed on the liquid crystal display, and the CD ship mode is set.

Note: Confirm each contents of this section first of all. If the results are

not satisfied, do the adjustment.

0 dB=0.775 V

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

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 circuit adjustment should be completed before performing recording circuit adjustment.)

6. The adjustments should be performed for both L-CH and RCH.

7. Switches and controls should be set as follows unless otherwise specified.
