SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK!OR DOTTED LINEWITH
MARK !ONTHE SCHEMATIC DIAGRAMS AND INTHE 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 PAR UNE MARQUE !SUR LES
DIAGRAMMES SCHÉMATIQUES 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.
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer:
Checkthe antenna terminals, metal trim, “metallized”knobs, screws,
and all other exposed metal parts forAC leakage. Check leakage as
described below.
LEAKAGE
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. Acommercial 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-operatedAC 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 2VAC range are suitable. (See
Fig. A)

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 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
Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type recommended by
the manufacturer.
Discard used batteries according to the manufacturer’s instructions.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.

SERVICING NOTE
[About Switches on POWER Board]
•Backup Power ON/OFF Switch (S1351 B. UP ON)
Be sure to turn this switch to OFF when removing and inserting connectors to and from the circuit boards.
This switch protects semiconductors from breakdown due to static electricity.
Set this switch to ON during normal operation. The DPA-300 does not work unless this switch is set to ON.
•Reset Switch (S1352 RESET)
This switch resets forcibly system of DPA-300. Press the reset switch when microprocessor runs away, or when DPA-300 does not
operate normally, or when the main power is desired to turn ON, OFF and back ON momentarily during test mode, etc.

5. PRECAUTIONS FOR USE OFTEST MODE
1. As loading related operations will be performed regardless of
the test mode operations being performed, be sure to check that
the disc is stopped before setting and removing it. Even if the
6button is pressed while the disc is rotating during continuous
playback, continuous recording, etc., the disc will not stop
rotating. Therefore, it will be ejected while rotating. Be sure to
pressthe 6button after pressing the Nbuttonand the rotation
of disc is stopped.
2. The erasing-protection tab is not detected in the test mode.
Therefore, operating in the recording laser emission modes
suchas continuous resord mode, traverse adjustment mode, etc.,
the recorded contents will be erased regardless of the position
of the tab. When using a disc that is not to be erased in the test
mode, be careful not to enter the continuous recording mode
and traverse adjustment mode.

SECTION 5
ELECTRICAL ADJUSTMENTS
Precautions for Adjustments
1) When replacing the following parts, perform the adjustments
and checks with ®in the order shown in the following table.
2) Set the test mode when performing adjustments.
After completing the adjustments, exit the test mode.
3) Perform the adjustments in the order shown.
4) Use the following tools and measuring devices.
• Check Disc (CD) TGYS-1 (Parts No. 4-963-646-01)
• Laser power meter LPM-8001 (Parts No. J-2501-046-A)
• Oscilloscope
• Digital voltmeter
• Thermometer
5) When observing several signals on the oscilloscope, etc.,
make sure that VC and ground do not connect inside the
oscilloscope.
(VC and ground will become short-circuited.)
Creating Continuously Recorded Disc
* This disc is used in focus bias adjustment and error rate check.
The following describes how to create a continuous recording
disc.
1. Insert a MO disc (blank disc) commercially available.
2. Press the , buttons and display “CREC MODE”.
3. Press the nbutton and display “CREC IN”.
4. Press the nbutton again to display “CREC MID”.
“CREC (0300” is displayed for a moment and recording starts.
5. Complete recording within 5 minutes.
6. Press the Nbutton and stop recording .
7. Press the §button and remove the MO disc.
The above has been how to create a continuous recording data for
the focus bias adjustment and error rate check.
Note :
• Be careful not to apply vibration during continuous recording.

All of the messages described as “displayed” appears on monitor
screen during adjustment.
Precautions for Checking Laser Diode Emission
To check the emission of the laser diode during adjustments, never
view directly from the top as this may lose your eye-sight.
Precautions for Use of optical pick-up (KMS-210A)
As the laser diode in the optical pick-up is easily damaged by static
electricity, solder the laser tap of the flexible board when using it.
Beforedisconnectingtheconnector,desolderfirst.Beforeconnecting
theconnector,becarefulnot to remove thesolder.Also takeadequate
measures to prevent damage by static electricity. Handle the flexible
board with care as it breaks easily.

– 0
Temperature Compensation Offset Adjustment
Save the temperature data at that time in the non-volatile memory
as 25 ˚C reference data.
Note :
1. Usually, do not perform this adjustment.
2. Perform this adjustment in an ambient temperature of 22 ˚C to
28 ˚C. Perform it immediately after the power is turned on
when the internal temperature of the unit is the same as the
ambient temperature.
3. When D101 has been replaced, perform this adjustment after
the temperature of this part has become the ambient
temperature.
Adjusting Method :
1. Press the , buttons and display “TEMPADJUST”.
2. Press the nbutton and select the “TEMPADJUST” mode.
3. “TEMP = ” and the current temperature data will be
displayed.
4. To save the data, press the nbutton.
When not saving the data, press the Nbutton.
5. When the nbutton is pressed, “TEMP= SAVE” will be
displayed for some time, followed by “TEMPADJUST”.
When the Nbutton is pressed, “TEMP ADJUST” will be
displayed.
Specifications :
The “TEMP = ” should be within “E0 - EF”, “F0 - FF”, “00 -
0F”, “10 - 1F” and “20 - 2F”.
