SECTION 1

SERVICING NOTES

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 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.

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 manuf acturers’ 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 v oltmeter. The “limit” indication
is 0.75 V, so analog meters must hav e an accurate low-v oltage
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 A C range are suitable. (See
Fig. A)

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

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

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.

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.

UNLEADED SOLDER

Boards requiring use of unleaded solder are printed with the lead­free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with

the lead free mark due to their particular size)

: LEAD FREE MARK

Unleaded solder has the following characteristics.

• Unleaded solder melts at a temperature about 40 °C higher
than ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350 °C.
Caution: The printed pattern (copper foil) may peel away if

the heated tip is applied for too long, so be careful!

• Strong viscosity
Unleaded solder is more viscou-s (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.

• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.

[CD SERVICE MODE]

This mode can move the SLED of the optical pick-up, and also can
turn the optical pick-up laser power on and off.

Procedure:

1. Press the @/1 button to turn the power on.

2. Press three buttons of CD u ,
simultaneously.

4. It enters the CD service mode and displays “SERVICE”.

5. To exit from this mode, press three buttons of CD u ,
and DISPLAY simultaneously.

Use these keys to move the SLED. When
TUNING+
SLED moves to outer circumference and the message
“SLED OUT” is displayed.
When

the SLED moves to inner circumference and the
message “SLED IN” is displayed.

Use this key to turn the optical pick-up laser power
on and off. When the laser power is turned on, the
message “LD ON” is displayed. When the laser
power is turned off, the message “LD OFF” is
displayed.

[CD ERROR CODE]

The past errors of the CD mechanism (CDM) are displayed as the
CDM Errors, and those of the optical pick-up system (= optical unit
+ BD board) are displayed as the BD Errors as shown below.

Procedure:

1. Press the @/1 button to turn the power on.

2. Press the FUNCTION button to select CD function.

3. Press three buttons of CD u , x and DISPLAY
simultaneously.

4. Then, the CDM error code is displayed as “M0xxxxxx” (x
means hexadecimal number) on the LCD screen as shown
below.

5. Every pressing of the TUNING+
increments the number after “M” starting from “M0” up to
“M9”, and then returns to “M0”. Every pressing of the

newer the error content is.

6. When the PLAY MODE/TUNING MODE b utton is pressed
then, the BD error code is displayed as “D0xxxxxx” (x means
hexadecimal number) on the LCD screen as shown below. In
the same way as the CDM error code, use of the
TUNING+
this mode enables tracing of the error history.

Procedure:

1. Turn the power on.

2. Input the following signal from Signal Generator to FM
antenna input directly.

* Carrier Freq: A = 87.5 MHz, B = 98 MHz, C = 108 MHz

Deviation : 75 kHz
Modulation : 1 kHz

Note: Please use 75 ohm “coaxial cable” to connect SG and the set. You

cannot use video cable for checking.
Please use SG whose output impedance is 75 ohm.

3. Set to FM tuner function and scan the input FM signal with
automatic scanning.

4. Confirm that input Frequency of A, B and C are detected and
automatic scanning stops.

The stop of automatic scanning means “The station signal is received

(In addition to this, the necessary note is printed in each block.)

Note on Schematic Diagram:

• All capacitors are in µF unless otherwise noted. (p: pF)
50 WV or less are not indicated except f or electrolytics and
tantalums.

• All resistors are in Ω and
specified.

• f : internal component.

• 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.

• H : adjustment for repair.

• A : B+ Line.

• B : B– Line.

•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.
