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 solderingor unsoldering.
CAUTIONUse of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation

SERVICING NOTES
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 therepair parts.
The flexible board is easily damaged and should be handled with
care.
NOTES ON LASER DIODE EMISSION CHECKThe 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 objective lens.
UNLEADED SOLDERBoards 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 MARKUnleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40 ˚C higherthan 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 viscosityUnleaded 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 solderIt is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.
ANTITHEFT UNLOCK MODEProcedure:

CD POWER MANAGEThis mode is used to changed over CD power on/off for decreasing
of reception noise in the tuner mode.
Procedure:
1. Press the I/ 1 button to turn the power on.
2. Press the [FUNCTION] button to select “CD” (BX5BT/CBX1).
Press the [CD] button on the remote commander to select “CD”
(CBX3).
3. Press the I/ 1 button again to turn the power off.
4. Press two buttons of [/CANCEL] and I/ 1 simultaneously.
5. The message “CD POWER ON” or “CD POWER OFF”is
displayed on the liquid crystal display, and CD power on/off
is changed over in the tuner mode.
CD SERVICE MODEThis mode can run the CD sled motor freely. Use this mode, for
instance, when cleaning the optical pick-up.
Procedure:
1. Press the I/ 1 button to turn the power on.
2. Press the [FUNCTION] button to select “CD” (BX5BT/CBX1).
Press the [CD] button on the remote commander to select “CD”(CBX3).
3. Press three buttons of [/CANCEL], [CD] and Z simul-
taneously, the message “SERVICE M” is displayed on the liq-
uid crystal display.
4. Press the [TUNE---] button to move the optical pick-up to inside
track and the message “SLED IN” is displayed on the liquid
crystal display, or press the [TUNE+] button to outside track
and the message “SLED OUT” is displayed on the liquid
crystal display.
5. Press the [CD] button, “LD ON” or “LD OFF” is dis-
played on the liquid crystal display. Each time [CD]
button is pressed, laser diode on/off is changed over.
6. To release this mode, press the I/ 1 button.
BT TEST MODE(BX5BT)This mode is used to check the firmware version and address of
bluetooth module.
Procedure:
1. Press the I/ 1 button to turn the power on.
2. Press the [FUNCTION] button to select “BLUETOOTH”.
3. Press three buttons of [DSGX], [BLUTOOTH] and [BLU-
TOOTHOPR] simultaneously, the message “BT Test” is dis-
played on the liquid crystal display. Then, the display is au-
tomatically changed to the firmware version of bluetooth
module.
4. Press the [DISPLAY] button, address of bluetooth module is
displayed on the liquid crystal display.5. To release this mode, press the I/ 1 button.

ELECTRICAL CHECKS
CD SECTION
Note:1. CD Block is basically constructed to operate without adjustment.
2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated.
3. Use an oscilloscope with more than 10 MΩ 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.5. Check the focus bias check when optical pick-up block is replaced.
FOCUS BIAS CHECK
Procedure :
1. Connect oscilloscope to TP121 (RFI) and TP124 (VC) on the
CD board.
2. Press the I/ 1 button to turn the power ON.3. Set disc (YEDS-18) on the tray and press the CD u button
to playback.
4. Confirm that oscilloscope waveform is as shown in the figure
below. (eye pattern)
A good eye pattern means that the diamond shape (◊) in thecenter of the waveform can be clearly distinguished.

TUNER SECTION
FM TUNE LEVEL CHECK
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. Confirm “TUNED” is lit on the display for A, B and C signals.
When the selected station signal is received in good condition,
“TUNED” is displayed.
