SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE
WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE
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.

HCD-GTX777/GTX787/GTX888

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.

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.

• 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 fl ow) 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.

NOTES ON LASER DIODE EMISSION CHECK

The laser beam on this model is concentrated so as to be focused on
the disc refl ective 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 component in this product is capable
of emitting radiation exceeding the limit for
Class 1.

This appliance is
claassifi ed as a CLASS 1
LASER product. This
label is located on the
rear exterior.

CAUTION

Use of controls or adjustments or performance of procedures
other than those specifi ed herein may result in hazardous
radiation exposure.

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
OR BASE UNIT

The laser diode in the optical pick-up block may suffer electrostatic
breakdown 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 fl exible board is easily damaged and should be handled with
care.

ELECTRICAL ADJUSTMENTS

SECTION 5

TUNER SECTION 0 dB = 1 µV

[FM Tune Level Check]

FM signal generator

SET

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
ANT input : 35 dBu (EMF)

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 tune A, B and C signals.

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

The mark of “TUNED” means “The selected station signal is re­ceived in good condition.”

OUT (75 7)

DECK SECTION 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
specifi ed.

CD SECTION

[TEST DISC LIST]

Use the following test disc on test mode.

• CD: YEDS-18 (PART No. 3-702-101-01)
or
PATD-012 (PART No. 4-225-203-01)

Note:

1. CD Block is basically designed to operate without adjustment.
Therefore, check each item in order given.

2. Use YEDS-18 (3-702-101-01) unless otherwise indicated.

3. Use an oscilloscope with more than 10MW impedance.

4. Clean the object lens by an applicator with neutral detergent
when the signal level is low than specifi ed value with the
following checks.

[S-CURVE CHECK]

BD93 board

TP106(FE)

Procedure :

1. Connect an oscilloscope to TP106 (FE) and TP124 (VC).

2. Turn the power on.

3. Load a disc (YEDS-18) and actuate the focus search. (In
consequence of open and close the disc tray, actuate the focus
search)

4. Confi rm that the oscilloscope waveform (S-curve) is symmetrical
between A and B and confi rm peak to peak level within 3 ± 0.5
Vp-p.

• Take sweep time as long as possible and light up the

brightness to obtain best waveform.

Procedure :

1. Connect an oscilloscope to TP123 (RFO) and TP124 (VC).

2. Turn the power on.

3. Load a disc (YEDS-18) and playback.

4. Confi rm that oscilloscope waveform is clear and check if RF
signal level is correct or not.

Note: Clear RF signal waveform means that the shape “ ◊ ” can

be clearly distinguished at the center of the waveform.

Note on Printed Wiring Board:

• X : parts extracted from the component side.

• Y : parts extracted from the conductor side.

• : Pattern from the side which enables seeing.

(The other layer’s patterns are not indicated.)

Caution:
Pattern face side: Parts on the pattern face side seen from
(Conductor Side) the pattern face are indicated.

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.

• 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 viscous (sticky, less prone to fl ow) 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.

Note on Schematic Diagram:

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

• All resistors are in Ω and 1/
specifi ed.

• 2 : nonfl ammable resistor.

• C : panel designation.

Note: The components identifi ed by mark 0 or dotted line

with mark 0 are critical for safety.

Replace only with part number specifi ed.

• A : B+ Line.

• B : B– Line.

• Voltage and waveforms are dc with respect to ground

under no-signal (detuned) conditions.

• BD93 and Driver sections.

no mark : CD PLAY

• Except BD93 and Driver sections.

no mark : FM
( ) : CD PLAY
< > : TAPE PLAY
[ ] : TAPE REC
∗ : Impossible to measure

• 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.

• Circled numbers refer to waveforms.

Note:

• Due to standardization, replacements in
the parts list may be different from the
parts specifi ed in the diagrams or the com-
ponents used on the set.

• -XX and -X mean standardized parts, so
they may have some difference from the
original one.

• Items marked “*” are not stocked since
they are seldom required for routine ser­vice.

Some delay should be anticipated when

ordering these items.
