CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.
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.
Precautions for Laser Diode Emission Check
When checking the emission of the laser diode during adjustments, never view directly downwards as this may lead to
blindness.
Precautions for Using Optical Pick-up (LCX-2E)
As the laser diode inside the optical pick-up damages by static
electricity easily, solder the laser tap of the Optical pick-up
flexible board when handling. Also take the necessary measures
to prevent damages by static electricity. Handle the Optical pickup flexible board with care as it breaks easily.
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.

SECTION 1
SERVICING NOTE
1) When repairing this device with the power on, if you remove
the main board or open the upper panel assy, this device stops
working.
In this case, you can work without the device stopping by
fastening the hook of the OPEN/CLOSE switch (MAIN board
S809) with tape.
MAIN board S809
2) This set is designed to perform automatic adjustment for each
adjustment and write its value to EEPROM. Therefore, when
EEPROM (MAIN board IC802) has been replaced in service,
be sure to perform automatic adjustment and write resultant
values to the new EEPROM.
Refer to section 4 Test Mode (page 10) for details.

• When entered in the TEST MODE, this set provides the Overall
Adjustment mode which allows CD and MO discs to be automatically adjusted. In the Overall Adjustment mode , the system
discriminates between CD and MO discs, performs adjustments
in sequence automatically, and displays the faulty location if any
fault is found. In the Manual mode, selected adjustments can be
performed automatically.
• The attached remote control is used to operate the TEST MODE.
Unless otherwise specified in the text, the key means that on the
remote control.

Note:
• All capacitors are in µF unless otherwise noted. pF: µµF
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ω and 1/4 W or less unless otherwise
specified.
• A : B+ Line.
• Waveform
• Power voltage is dc 1.5V and fed with regulated dc power
supply from battery terminal.
• Voltage and waveforms are dc with respect to ground
under no-signal conditions.
no mark : PB

• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production tolerances.
• Circled numbers refer to waveforms.
