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
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 label is located on the rear
exterior.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0OR DOTTED LINEWITH
MARK 0ON THE 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.
Unleaded solder
Boards requiring use of unleaded solder are printed with the lead
free 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.
•Unleadedsoldermeltsat a temperature about40°Chigherthan
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 viscous (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.
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer:
Checktheantenna terminals, metaltrim, “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. Abattery-operatedAC milliammeter. The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOMorbattery-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

SERVICING NOTES
NOTES ON HANDLINGTHE 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 pick-
up 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
Carryoutthe“S curve check”in“CD section adjustment” andcheck
that the S curve waveform is output several times.

[MC TEST MODE]
•Thismodeis usedtocheck operations oftherespective sections
of Amplifier and Tape.
Procedure:
* To enter MC Test Mode
1. Press xbutton, [ENTER] button and [DISC 3] button
simultaneously.
2. The CD ring indicators, TAPEAandTAPE B indicators flash
on the fluorescent indicator tube. The function is changed to
VIDEO.
* Check of Amplifier
1. Press [EQ BAND] button repeatedly until a message “GEQ
MAX” appears on the fluorescent indicator tube. GEQ
increases to its maximum.
2. Press [EQ BAND] button repeatedly until a message “GEQ
MIN”appearson thefluorescentindicator tube.GEQdecreases
to its minimum.
3. Press [EQ BAND] button repeatedly until a message “GEQ
FLAT” appears on the fluorescent indicator tube. GEQ set to
flat.
4. When the [MASTER VOLUME] knob is turned clockwise even
slightly, the sound volume increases to its maximum and a
message “VOLUME MAX” appears on the fluorescent
indicator tube.
5. Whenthe[MASTER VOLUME] knobisturned counter-clockwise
even slightly, the sound volume decreases to its minimum and
a message “VOLUME MIN” appears on the fluorescent
indicator tub.
* Tape function
1. When a tape is inserted in Deck B and recording is started, the
functionischanged toVIDEO automatically.When [CD SYNC]
buttonispressed duringrecordingin function,ALC(Automatic
Logic Control) is turned on.
2. During recording, turn
M
m
knob counter- clockwise
will stop the recording and the function is changed to TAPE B
and rewind the tape in deck B until the recording start position
and playback of the tape in deck B is started. If the [REC
PAUSE/ START] button is pressed for a pause and pressed
again to resume recording during recording time, when the
tape in deck B is rewind, the tape in deck B will be rewind
until the position where the pause is applied.
* To release MC Test mode.
1. To release this mode, press ?/1 button.
2. The cold reset is enforced at the same time.
[COLD RESET]
•The cold reset clears all data including preset data stored in
the RAM to initial conditions. Execute this mode when
returning the set to the customer.
Procedure:
1. Press xbutton, [ENTER] button, and ?/1 button
simultaneously.
2. The fluorescent indicator tube becomes blank for a while, and
the set is reset.
[GCTEST MODE]
•This mode is used to check the fluorescent indicator tube,
LEDs, keys, MASTER VOLUME jog, OPERATION
DIAL jog, AMS jog, destination, software version and
VACS level.
Procedure:
1. Press xbutton, [ENTER] button and [DISC 2] button
simultaneously.
2. AllLEDsand segments influorescent indicator tubearelighted
up.All LEDs are lighted up in red color. If the system is turned
on, the `/1 LED is lighted up in green color.
3. When you want to enter the software version display mode,
press[DISC 1] button.The model anddestination are displayed.
4. Each time [DISC 1] button is pressed, the display changes from
MC version, GC version, SYS version, CD version, CDDM
version, CDMAversion, CDMB version, BDAversion, BDB
version, ST version, TC version, TA version and TM version
in this order, and returns to the MC version display.
5. When [DISC 3] button is pressed while the version numbers
are being displayed except model and destination, the date of
the software creation appear. When [DISC 3] button is pressed
again,thedisplay returns tothesoftware version display.When
[DISC 1] button is pressed while the date of the software
creation is being displayed, the date of the software creation
is displayed in the same order of software version display.
6. Press [DISC 2] button, the key check mode is activated.
7. In the key check mode, the fluorescent indicator tube displays
“K 0 J0V0E0 X0”.
Each time a button is pressed, “K” value increases. However,
once a button has been pressed, it is no longer taken into
account.
