SECTION 1
SERVICING NOTE
• When repairing this device with the power on, if you remove
the MAIN board or open the upper panel assy, this device stops
working.
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electro-
static break-down because of the potential difference generated
by the charged electrostatic load, etc. on clothing and the human
body.
In this case, you can work without the device stopping by fas-
tening the hook of the open/close detect switch (S801) with tape.
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
Never look into the laser diode emission from right avove when
checking it for adustment. It is feared that you will lose your sight.
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
(LCX-2R)
Tape
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.
MAIN board
S801
• This set is designed to perform automatic adjustment for each
adjustment and write its value to EEPROM. Therefore, when
EEPROM (IC802) has been replaced in service, be sure to per-
form automatic adjustment and write resultant values to the new
EEPROM.
(Refer to page 20.)
laser-tap
• Replacement of CXD2660R (IC502) and CXR701081 (IC801)
used in this set requires a special tool. Therefore, they cannot be
replaced.

4-1. OUTLINE
pressing the x key on the set, press the following remote
control keys in the following order:
• This set provides the Overall adjustment mode (Assy mode) that
allows CD and MO disc to be automatically adjusted when in
the test mode. In this overall adjustment mode, the protect switch
is detected to judge the disc, CD or MO, and each adjustment is
automatically executed in order. If a fault is found, the system
displays its location. Also, the manual mode allows each indi-
vidual adjustment to be automatically adjusted.
• The keys in the description refer to the keys on both set and
remote commander unless otherwise specified. Though LCD
display shows the LCD of the remote commander, same con-
tents are also displayed on the LCD of the set.

4-2-2. Operation in Setting the Test Mode
• When the test mode becomes active, first the display check mode
is selected. (Press x key once, when the display check mode
is not active.)
• Other mode can be selected from the display check mode.
• When the test mode is set, the LCD repeats the following dis-
play.
4-2. TEST MODE
4-2-1. Setting Method of Test Mode
There are two different methods to set the test mode:
1 Short BP801 (TEST) on the MAIN board with a solder bridge
(connect pin y; of IC801 to the ground). Then, turn on the
power.

• When the X key is pressed and hold down, the display at that
time is held so that display can be checked.
4-2-3. Releasing the Test Mode
For test mode set with the method 1:
Turn off the power and open the solder bridge on BP801 (TEST)
on the MAIN board.
Note: Remove the solders completely. Remaining could be shorted with
the chassis, etc.
For test mode set with the method 2:
Turn off the power.
Note: If electrical adjustment (see page 20) has not been finished com-
pletely, always start in the test mode. (The set cannot start in nor-
mal mode.)

4-6. SELF-DIAGNOSIS DISPLAY MODE
• This set uses the self-diagnosis system in which if an error oc-
curs in recording/playback mode, the error is detected by the
model control and power control blocks of the microprocessor
and information on the cause is stored as history in EEPROM.
By viewing this history in test mode, it helps you to analyze a
fault and determine its location.
Total recording time has been recorded as optical pick-up using
time, and it is compared with the total recording time in the
self-diagnosis display mode to find when an error occurred.
Clear both total recording time and the time in self-diagnosis
display mode, when the optical pick-up was replaced.
1. Setting the test mode. (See page 13)
2. Press the MENU . key on the set or press the [DISPLAY]
key on the remote commander activates the self-diagnosis dis-
play mode where the LCD display as shown below.

2. Move up the jog key on the set or press the [DISPLAY] key on the remote commander activates the self-diagnosis display mode.
3. Press the X key or [REC] key on the set during display of self-diagnosis data when clearing the self-diagnosis data, or during display of
total recording time when clearing the total recording time. Thus, “ClrOK?” will be displayed on the LCD, and press the same key again,
and when self-diagnosis data is cleared “ErrCLR” is displayed and the data is cleared. Also when total recording time is cleared, “ RecT
O” is displayed and it is cleared.
