Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270 ˚C dur-
ing 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 dam-
aged by heat.
This appliance is classified as a CLASS 1 LASER product.
The CLASS 1 LASER PRODUCT MARKING is located on
the rear exterior.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.
On AC power adaptor
• Use only the AC power adaptor supplied or
recommended in “Accessories (supplied/
optional).” Do not use any other AC power
adaptor.  It may cause a malfunction.

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.
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 objective lens.

 CD SECTION
Note:
1. CD Block is basically designed to operate without adjustment.
There-fore, check each item in order given.
2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated.
Use a disc copied from YEDS-18 for CD-RW test.
3. Use an oscilloscope with more than 10M
Ω 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.
OP FE Offset Adjustment
Procedure:
1.
Connect a digital multimeter to test point TP704 (FE,Y F X)
and TP703 (VREF) with DC range.
2.
Turn on the power, while pressing two buttons  u  and
 PLAY MODE  simultaneously. “
88” is displayed.
3.
Press the  x  button,then press the  PLAY  MODE  button.
Adjust the RV701 after the message “
82” is displayed.
4.
Press the  PLAY MODE  twice. Adjust the RV702 after the
message “
82” is displayed and “REP” blinks.

OP TE Offset Adjustment
Procedure:

and TP703 (REF) with DC range.
2.
Put the disc (YEDS-18)  in.
3.
Press the  u  button.
4.
Adjust the RV703 after TOC reading.
TE Specified value: VREF – (100

RF Waveform Check
Procedure:
1.
Connect an oscilloscope to test point TP702 (RF) and TP703
(VREF) on the CD board.
2.
Put the Disc (YEDS-18 or copied from YEDS-18) in.
3.
Press the  u  button.
4.
Confirm that oscilloscope waveform is clear.
Note:
A clear RF signal waveform means that the shape “
