SECTION 1

SERVICING NOTES

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.

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.

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
exterior.

Laser component in this product is capable of emitting radiation
exceeding the limit for Class 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 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

CX-LDB30/LDB50

[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. Press the ?/1 button to turn off the main power.

2. Press two buttons of [AUDIO IN] and ?/1 simultaneously for

more than two seconds.

3. The fluorescent indicator tube does not display any message
and the set is reset.

[COMMON TEST]

*This mode is used to check the function of the amplifier.

Procedure:

1. Press the ?/1 button to turn the set on.

2. Press two buttons of x and [DISPLAY] simultaneously for
more than two seconds.

3. The message “Volume MAX” is displayed, when the
[VOLUME] knob is rotated clockwise. The message “Volume
MIN” is displayed, when the [VOLUME] knob is rotated
counterclockwise.

4. Each time the [BASS] or [TREBLE] knob is turned or Press the
[EQ] button (RM), the message “TONE MAX”, “TONE MIN”
