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 dur-

ing 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
VOM or battery-operated AC voltmeter. The “limit” indication
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 VOM that is suitable. Nearly all battery operated digital
multimeters that have a 2 V AC range are suitable. (See Fig. A)

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

The following caution label is located inside the unit.

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.

TEST MODE

[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 ?/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 fluorescent indicator tube, and the
CD ship mode is set.

[GC Test Mode]

• This mode is used to check the software version, FL tube, LED,
keyboard and VACS.

Procedure:

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

taneously.

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

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

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

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

MC version, GC version, CD version, CDD version, CDM
version, BD version, ST version, TA version, TM version, TC
version and MD version in this order.

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

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

“K 0 J 0 V 0”. 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 VOLUME knob
in “+” direction, or it decreases like 0, 9, 8 ... if rotating in
“–” direction.

7. To exit from this mode, press three buttons in the same manner

as step 1, or disconnect the power cord.

[CD Service Mode]

• This mode can run the CD sled motor freely. Use this mode , for
instance, when cleaning the optical pick-up.

Procedure:

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

2. Select the function “CD”.

3. Press three buttons x (TAPE A), x (CD), and CD 2 simulta-

neously.

4. The CD service mode is selected.

5. With the CD in stop status, turn the shuttle knob clockwise to

move the optical pick-up to outside track, or turn the shuttle
knob counter-clockwise to inside track.

6. To exit from this mode, perform as follows:

1) Move the optical pick-up to the most inside track.

2) Press three buttons in the same manner as step 2.

Note: • Always move the optical pick-up to most inside track when exit-

ing from this mode. Otherwise, a disc will not be unloaded.

• Do not run the sled motor excessively , otherwise the gear can be
chipped.

[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 ?/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 fluorescent indicator tube, 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.

CD SECTION

Note:

1. CD Block is basically constructed to operate without
adjustment.

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.

5. Check the focus bias check when optical block is replaced.

Procedure :

1. Connect oscilloscope to TP (RF) and TP (VC) on the CD board.

2. Press the I/1 button to turn the power on, and press the Z
(CD) button to open the CD disc tray.

3. Put disc (YEDS-18) in and press the u (CD) b utton to play­back.

4. Confirm that oscilloscope waveform is as shown in the figure
below. (eye pattern)
A good eye pattern means that the diamond shape ( ) in the
center of the waveform can be clearly distinguished.
