SECTION 1
SERVICING NOTES
When repairing this device with the power on, if you remove the
main board, this device stops working.
In this case, you work without the device stopping by fastening the
hook of the Open/Close detection switch (S809).
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.
Open/Close detection switch (S809)
The flexible board is easily damaged and should be handled with
care.
NOTES ON LASER DIODE EMISSION CHECK
Never look into the laser diode emission from right above when
checking it for adjustment. It is feared that you will lose your sight.
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
(LCX-4E)
The laser diode in the optical pick-up block may suffer electrostatic
break-down easily. When handling it, perform soldering bridge to
the laser-tap on the flexible board. Also perform measures against
electrostatic break-down sufficiently before the operation. The
flexible board is easily damaged and should be handled with care.
* Replacement of CXD2671-205GA (IC601) used in this set
requires a special tool.

4-1. GENERAL
• When entered in the TEST MODE, this set provides the Overall
Adjustment mode which allows CD and MO discs to be auto-
matically 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.

main board.
Note : The solder should be removed clean. The remaining solder
may make a short with the chassis and other part.
When method 2 was used:
Turn off the power.
Note : If electrical adjustment (see page 12) has not been finished
completely, always start in the test mode. (The set cannot

• Power voltage is dc 1.5V and fed with regulated dc power
supply from battery terminal.
• Voltages and waveforms are dc with respect to ground
under no-signal conditions.
no mark : PLAY
• Voltages are taken with aVOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-

• The voltage and waveform of CSP (chip size package)
cannot be measured, because its lead layout is different

• Voltages are taken with a VOM (Input imped-
ance 10 MΩ).
• All capacitors are in µF unless otherwise noted.
pF: µµF 50 WV or less are not indicated except
for electrolytics and tantalums.
* Replacement of IC601 used in this set requires
a special tool.
• The voltage and waveform of CSP (chip size
package) cannot be measured, because its lead
layout is different from that of conventional IC.
Voltage variations may be noted due to normal
production tolerances.
