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.

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 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-operated AC 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 2 V AC range are suitable. (See
Fig. A)

SERVICING NOTES

HCD-GTZ4/GTZ4i/GTZ5

Ver. 1.1

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 fl exible 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 refl ective 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.

UNLEADED SOLDER

Boards requiring use of unleaded solder are printed with the lead­free 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.

TEST MODE

PANEL TEST MODE

This mode is used to check the fl uorescent indicator tube, LEDs,
keys, [MASTER VOLUME] jog, [OPERATION DIAL] jog, mod­el, destination and software version.

Procedure:

1. Press [x], [METER MODE] and [DISC 2] buttons simultane­ously.

2. All LEDs and segments in fl uorescent indicator tube are light-
ed up.

3. When you want to enter to the software version display mode,
press [DISC 1] button. The model information appears on the
fl uorescent indicator tube. “GTL 2S” or “GTL 2SI” is shown
for HCD-GTZ4/GTZ4i, “GTL 3S” is shown for HCD-GTZ5.
Press [DISC 1] button again to view the destination informa­tion.

4. During the destination information display, press [DISC 1]
button. Each time [DISC 1] button is pressed, the fl uorescent
indicator tube shows the version of each category software
in the following sequence: SC, MTK (DMB board fi rmware
version), GC, SYS, CD, CDMA, CDMB, ST, TA, TM, MTR
(METER) and return back to model information 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 appears. When [DISC 3] button is
pressed again, the display returns to the software 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 fl uorescent indicator tube displays
“K 0 J0 V0”.

Each time a button is pressed, “K” value increases. However,

once a button has been pressed, it is no longer taken into ac­count.

“V” value increases in the manner of 0,1, 2, 3 ... if [MASTER

VOLUME] knob is turned clockwise, or it decreases in the
manner of 0, 9, 8,7 ... if [MASTER VOLUME] knob is turned
counterclockwise.

“J” value increases in the manner of 0,1, 2, 3 ... if [OPERA TION

DIAL] knob is turned clockwise, or it decreases in the manner
of 0, 9, 8, 7 ... if [OPERATION DIAL] knob is turned
counterclockwise.

8. When [DISC SKIP/EX-CHANGE] button is pressed after all
LEDs and segments in fl uorescent indicator tube light up, al-
ternate segments in fl uorescent indicator tube and LEDs would
light up. If you press [DISC SKIP/EX-CHANGE] button
again, another half of alternate segments in fl uorescent indi-
cator tube and LEDs would light up. Pressing [DISC SKIP/
EX-CHANGE] button again would cause all segments in fl uo-
rescent indicator tube and LEDs light up.

9. To release from this mode, press three buttons in the same
manner as step 1, or disconnect the power cord.

COMMON TEST MODE

This mode is used to check operations of the respective amplifi er
section.

To enter common test mode
Procedure:

1. Press [x], [METER MODE] and [DISC 3] buttons simultane­ously.

2. The CD ring indicators fl ash on the fl uorescent indicator tube.
The function is changed to PC and the volume is changed to
VOLUME MIN.

Check of amplifi er
Procedure:

Procedure:

1. Turn on the set.

2. Input the following signal from signal generator to FM antenna
input directly.

Carrier frequency : A = 87.5 MHz, B = 98 MHz, C = 108 MHz
Deviation : 75 kHz
Modulation : 1 kHz
ANT input : 35 dBu (EMF)

Note: Use 75 ohm coaxial cable to connect signal generator and the set.

You cannot use video cable for checking.

Use signal generator 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.

When the selected station signal is received in good condition,
