Notes on chip component replacement

• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be dam-

aged 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
circuit board (within 3 times).

• Be careful not to apply force on the conductor when soldering
or unsoldering.

SAFETY CHECK-OUT

After correcting the original service problem, perform the follow­ing 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 leaka ge tester, such as the Simpson 229 or RCA

WT -540A. Follo w 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-operated AC voltmeter. The “limit” indica­tion is 0.75 V, so analog meters must have an accurate low­voltage 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)

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.
The CLASS 1 LASER
PRODUCT MARKING is
located on the rear exterior.

The following caution label is located inside the unit.

SERVICING NOTES

HCD-XG60/XG500

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
pick-up block. Therefore, when checking the laser diode emis­sion, observe from more than 30 cm away from the objecti ve 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

HCD-XG60/XG500

[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 [ /CLOCK SET], [ENTER/NEXT], and

?/1 simultaneously.

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

DEMO mode.

[MC Hot Reset]

• This mode resets the set with the preset data kept stored in the

memory. The hot reset mode functions same as if the power
cord is plugged in and out.

Procedure:

1. Turn the power ON or set to the DEMO mode.

2. Press three buttons of [ /CLOCK SET], [ENTER/NEXT],

and [DISC 1] simultaneously.

3. The set is reset, and becomes standby state.

[Change-over the AM Tuning Interval]
(EXCEPT AEP, UK, and Saudi Arabia models)

• 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 Delivery Mode]

• 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.

2. Press the [LOOP] and ?/1 buttons simultaneously.

3. A message “LOCK” is displayed on the fluorescent indicator

tube, and the CD delivery mode is set.

[LED and Fluorescent Indicator Tube All Lit, Key Check
Mode]

Procedure:

1. Press three buttons of [ /CLOCK SET], [ENTER/NEXT],

and [DISC 2] simultaneously.

2. LEDs and fluorescent indicator tube are all turned on.

Press the [DISC 2] button, and the key check mode is acti­vated.

3. In the key check mode, the fluorescent indicator tube displays

“K 0 J0 V0”. Each time a button is pressed, “K” value in­creases. However , once a button is pressed, it is no longer taken
into account.
“J” value increases like 1, 2, 3 ... if turn the JOG dial clock­wise, or it decreases like 0, 9, 8 ... if turn the JOG dial counter­clockwise.
“V” value increases like 1, 2, 3 ... if turn the [VOLUME] dial
clockwise, or it decreases like 0, 9, 8 ... if turn the JOG dial
counterclockwise.

4. To release from this mode, press three buttons in the same

manner as step 1, or disconnect the power cord.

[Aging Mode]

This mode can be used for operation check of tape deck section.
Tape deck section work in parallel.

• If an error occurred:
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] b utton to set the “ ALL DISCS” mode,

and press the [REPEAT] button to “REPEAT” off.

4. Press three buttons of [ /CLOCK SET], [ENTER/NEXT],

c

and [DISC 4] simultaneously.

5. The aging mode is activated, if the indicator of disc tray num-

ber 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”)

1. Display at the Aging Mode

• Display operating state of tape deck section alternately.

• If an error occurred, stop display.

2. Tape Deck Section

• The sequence during the aging mode is following as below.

• If an error occurred, stop display that step.

Precaution

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

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 specified.

8. Set to the DOLBY NR OFF.

Note on Schematic Diagram:

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

• All resistors are in Ω and 1/
specified.

• 2 : nonflammable resistor .

• 5 : fusible resistor.

• C : panel designation.

Note:

The components identi­fied by mark 0 or dotted
line with mark 0 are criti­cal for safety.
Replace only with part
number specified.

• A : B+ Line.

• B : B– Line.

• H : adjustment for repair.

• 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.

• Signal path.
