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.
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.
Notes on the power source
Disconnect all power sources when the CD player is not used for a
long time.
On AC power adaptor
• Use only the AC power adaptor supplied.
If your CD player is not supplied with the one, use the A C-E30HG
AC power adaptor. Do not use any other AC power adaptor. It
may cause a malfunction.

UNLEADED SOLDER
Boards 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 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 f low)
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.
• Do not touch the AC power adaptor with wet hands.
• Connect the A C po wer adaptor to an easily accessible AC outlet.
Should you notice an abnormality in the AC power adaptor,
disconnect it from the AC outlet immediately.

SECTION 1
SERVICE NOTE
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic breakdown because of the potential difference generated by
the charged electrostatic load, etc. on clothing and the human body .
During repair, pay attention to electrostatic breakdown 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.
Precautions for Checking Emission of Laser Diode
Laser light of the equipment is focused by the object lens in the
optical pick-up so that the light focuses on the reflection surface
of the disc. Therefore, be sure to keep your eyes more then 30 cm
apart from the object lens when you check the emission of laser
diode.
Before Replacing the Optical Pick-Up Block
Please be sure to check throughly the parameters as par the “Optical Pick-Up Block Checking Procedures” (Part No.: 9-960-027-
11) issued separately before replacing the optical pick-up block.
Note and specifications required to check are given below.
• FOK output : IC601 yg pin (or TP624 (FOK))
When checking FOK, remove the lead wire to disc motor.
• RF signal P-to-P value : 0.45 ± 0.1 Vp-p
• The repairing grating holder is impossible.
Laser Diode Checking Methods
During normal operation of the equipment, emission of the laser
diode is prohibited unless the upper lid is closed while turning ON
the S803. (push switch type)
The following two checking methods for the laser diode are
operable.

• Method:
Emission of the laser diode is visually checked.
1. Open the upper lid.
2. With a disc not set, turn on the S803 with a screwdriv er having a
thin tip.
Note: Do not push the detection lever strongly , or it may be bent
or damaged.
3. Press the N X button.
4. Obser ving the objective lens, check that the laser diode emits
light.
When the laser diode does not emit light, automatic power
control circuit or optical pick-up is faulty.
In this operation, the objective lens will move up and down 5
times along with inward motion for the focus search.

FOCUS BIAS CHECK
1. Connect the oscilloscope between TP610 (RF) and GND on
main board.
2. Insert the disc (YEDS-18). (Part No. : 3-702-101-01)
3. Press the N X button.
4. Confirm that the oscilloscope waveform is as shown in the
figure below. (eye pattern)
A good eye pattern means that the diamond shape ( ) in the
center of the waveform can be clearly distinguished.
• RF signal reference waveform (eye pattern)
VOLT/DIV : 20 mV (10 : 1 probe in use)
TIME/DIV : 500 nS
RF level :
0.45
±
0.1 Vp-p
When observing the eye pattern, set the oscilloscope for AC range
and raise vertical sensitivity.
