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.

HCD-XGV6/XGV8/XGV10AV

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 .

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.

TEST MODE

[MC 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.Turn the power ON or set to the DEMO mode.

2.Press three buttons of c/CLOCK SET , TUNER ENTER , and
\/1 simultaneously.

3. The set is reset, and displays “COLD RESET”, then becomes
DEMO mode.

[Change-over the AM Tuning Interval]

• The AM tuning interval can be changed over 9 kHz or 10 kHz.

Procedure:

1.Press the \/1 button to turn the power ON.

2.Select the function “TUNER”, and press the TUNER/BAND
button to select the BAND “AM”.

3. Press the \/1 button to turn the power OFF.

4. Press the ENTER/NEXT and \/1 buttons simultaneously,
and the display on the fluorescent indicator tube changes to
“AM 9 K STEP” or “AM 10 K STEP”, and thus the tuning
interval is changed over.

[CD Ship Mode] (No memory clear)

• This mode moves the optical pick-up to the position durable to
vibration. Use this mode when returning the set to the customer
after repair.

Procedure:

1.Press the \/1 button to turn the power ON.

about 5dB mute is applied to the input gain.

Procedure:

1. Press \/1 button to turn the power OFF.

2. Press
several seconds, and the power is turned on, the display of
fluorescent indicator tube changes to “MD” or “VIDEO”
instantaneously, and thus the FUNCTION is changed over.

[Aging Mode]

This mode can be used for operation check of tape deck section.

The aging operation stops and display then status.

• If no error occurs:
The aging operation continues repeatedly.

Procedure:

1.Load the tapes into the decks A and B respectively.

2.Press the FUNCTION button to select the function “CD”.

3.Press the PLAY MODE button to set the “ALL DISCS” mode,
and press the REPEAT button to “REPEAT” off.

4. Press three buttons of c/CLOCK SET , TUNER ENTER ,
and DISC 4 simultaneously.

5. The aging mode is activated, if the indicator of disc tray num­ber on the fluorescent indicator tube is blinking.

6. To release from the aging mode, press the \/1 button to turn
the power OFF and operate the cold reset. (Refer to the “MC
Cold Reset”)
