TEL

• 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

• 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. This marking is located

SAFETY CHECK-OUT

Q

TEL [phone] QQ 376315150 892498299

After correcting the original service problem, perform the following

Q

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

2. A battery-operated AC milliammeter. The Data Precision 245

3. Measuring the voltage drop across a resistor by means of a

instruments.

digital multimeter is suitable for this job.

VOM or battery-operated A C voltmeter . The “limit” indication
is 0.75 V, so analog meters must have 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)

Self-diagnosis Function

(When letters/numbers appear in the display)
When the self-diagnosis function is activated to prevent the system from

malfunctioning, a 5-character service number (e.g. C 13 50) with a
combination of a letter and 4 digits appears on the TV screen and the front
panel display. In this case, check the following table.

Cause and corrective action

• Clean the disc with a soft cloth.

• Restart the system, then re-insert the disc

correctly.

To prevent a malfunction, the system has
performed the self-diagnosis function.

• Contact your nearest Sony dealer or local

authorized Sony service facility and give
the 5-character service number.

NOTES ON HANDLING THE OPTICAL PICK-UP

Q

TEL [phone] QQ 376315150 892498299

BLOCK OR BASE UNIT

Q

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.

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

Unleaded solder has the following characteristics.

• Unleaded solder melts at a temperature about 40 °C higher

• Strong viscosity

• Usable with ordinary solder

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

13942296513

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.

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

FM TUNE LEVEL CHECK

Procedure:

TEL [phone] QQ 376315150 892498299

When the selected station signal is received in good condition,
“TUNED” is displayed.

Q

generator

1. Turn on the set.

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

Carrier frequency: A = 87.5 MHz, B = 98 MHz, C = 108 MHz

Deviation : 75 kHz
Modulation : 1 kHz
ANT input : 35 dBu (EMF)

Note: Use 75 ohm coaxial cable to connect signal generator and the set.

You cannot use video cable for checking.
Use signal generator whose output impedance is 75 ohm.

3. Set to FM tuner function and tune A, B and C signals.

4. Confirm “TUNED” is lit on the display for A, B and C signals.

RFMON LEVEL CHECK

Connection :

CN105 pin

Procedure :

1. Connect an oscilloscope to CN105 pin 6 (RFMON) and
CN105 pin 3 (GND) on the DMB15 board.

2. Press the I/1 button to turn on the system.

3. Insert the test disc (refer to “TEST DISC LIST”) and press
the DVD N button to playback.

4. Confirm that oscilloscope waveform is clear and check
RFMON signal level is correct or not.

Note: A clear RFMON signal wa veform means that the shape “◊” can be
