CAUTION
Use of controls or adjustments or performance of procedures

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. 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-63T rd 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)

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 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.

SERVICING NOTES
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 objectiv e 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.
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 viscou-s (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.

TEST MODE
CX-JN5
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. In the standby status, while pressing the x button, press the
[POWER] button.
2. The set is reset, then becomes standby status.
GC TEST MODE
Procedure:
1. Press the [POWER] button to turn the power on.
2. While pressing the x button, press the [POWER] button for
5 seconds.
3. It change displays in order of model type, version and suffix at
2 seconds interval, then the display is back to normal status.
AMP TEST MODE
Procedure:
1. In the status where AC plug is disconnected, while pressing
the [VIDEO/AUX] button, connect the AC plug to turn the
power on. Then enter the AMP test mode and display “AMP
TEST”.
2. If turn the [VOLUME] knob clockwise, it displays “V OLUME
MAX”, and if turn the knob counterclockwise, it displays
“VOLUME 0”.
3. If the [TREBLE] and [BASS] knobs are turned clockwise or
counterclockwise, it change displays in order of “EQ MAX”,
“EQ MIN” and “EQ FLAT”.
4. To release from this mode, disconnect the AC plug and turn
the power off.
CHANGE-OVER OF AM TUNER STEP BETWEEN
9 kHz AND 10 kHz
(Except AEP, UK and CIS models)
•A step of AM channels can be changed o ver between 9 kHz and
10 kHz.
Procedure:
1. Press the [POWER] button to turn the power on.
2. While pressing the [TUNER] button, press the [POWER] but-
ton to the display on fluorescent indicator tube changes to “AM
530 kHz” (10 kHz step) or “AM 531 kHz” (9 kHz step), and
thus the channel step is changed over.
FUNCTION CHANGE MODE
• Select either TV, VIDEO or AUX (MD) of the external function
input.
Procedure:
1. Press the [POWER] button to turn the power on.
2. While pressing the [VIDEO/AUX] button, press the [POWER]
button.
3. Each time this operation is operated, it change displays in or-
der of “TV”, “VIDEO” and “AUX”.
DISC TRAY LOCK
Procedure:
1. Press the
2. While pressing the x button, press the [ OPEN/CLOSE]
button for 5 seconds.
3. The message “LOCKED” is displayed and the tray is locked.
(Even if exiting from this mode, the tray is still locked)
4. To release this lock, while pressing the x button, press the
[ OPEN/CLOSE] button for 5 again.

5. The message “UNLOCKED” is displayed and the tray is unlocked.
CD REPEAT 5 LIMIT CANCEL MODE
• Number of repeat for CD playback is 5 times when the repeat
mode is “REPEAT”. This mode enables CD to repeat playback
for limitless times.
Procedure:
1. Press the [POWER] button to turn the power on.
2. In the repeat on status, while pressing the x button, press the
[POWER] button to turn the power on.

CD TEST MODE
•This mode can run the CD sled motor freely. Use this mode, for
instance, when cleaning the pickup.
Procedure:
1. In the status where AC plug is disconnected, while pressing
the [CD] button, connect the AC plug to turn the power on.
2. When enter this mode, it displays “CD TEST” and few sec-
onds later, all segments turn on of the fluorescent indicator
tube.
3. To release from this mode, disconnect the AC plug and turn
the power off.
In this mode, it operates as following table.

ELECTRICAL ADJUSTMENTS
CX-JN5
Ver 1.1
CD SECTION
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 10MΩ impedance.
4. Clean the object lens by an applicator with neutral detergent when the
signal level is low than specified value with the following checks.
S-CURVE CHECK
Oscilloscope
BD board
TP(FE)
TP(VC)
Procedure :
1. Connect an oscilloscope to TP (FE) and TP (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. Confirm that the oscilloscope waveform (S-curve) is
symmetrical between A and B. And confirm peak to peak level
within 3 ± 0.5 Vp-p.
Note: Clear RF signal waveform means that the shape “ ◊ ” can be clearly
distinguished at the center of the waveform.

6-4. NOTE FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
Note on Printed Wiring Board:
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
• x : parts mounted on the conductor side.
• : Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
Caution:
Pattern face side: Parts on the pattern face side seen from
(Conductor Side) the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(Component Side) the parts face are indicated.

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.
•Voltages and waveforms are dc with respect to ground
•Voltages are taken with a V OM (Input impedance 10 MΩ).
•Waveforms are taken with a oscilloscope.
• Circled numbers refer to waveforms.
• Signal path.
