SECTION 1  
SERVICING NOTES  
• In performing the repair with the power supplied to the set,  
removing the MAIN board causes the set to be disabled.  
In such a case, fix a convex part of the open/close detect switch  
(S806 on MAIN board) with a tape in advance.  
Handle the FLEXIBLE board (overwrite head) with care, as it  
has been soldered directly to the MAIN board.  
In repairing the component side of MAIN board, connect the  
FLEXIBLE board (overwrite head) and the MAIN board with  
the lead wires in advance. (See page 7)  
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.  
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.  
FLEXIBLE board  
(Over write head)  
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-4R)  
The laser diode in the optical pick-up block may suffer electro-  
static break-down easily. When handling it, perform soldering  
bridge to the laser-tap on the flexible board. Also perform mea-  
sures against electrostatic break-down sufficiently before the op-  
eration. The flexible board is easily damaged and should be handled  
with care.  
Tape

S806  
• Replacement of CXD2671-206GA (IC801) used in this set re-  
quires a special tool.  
• The shipment data will be cleared when the NV is reset. There-  
fore, change the adjusted values following the Change of Ad-  
justed Values immediately after the NV was reset. (See page  
18)  
laser-tap  
OPTICAL PICK-UP FLEXIBLE BOARD  
• If the nonvolatile memory was replaced on the set, the modified  
program data must be written to the nonvolatile memory. In such  
a case, write the modified data that meets the microcomputer  
version following the patch data rewriting procedure at the  
replacement of nonvolatile memory. (See page 23)  
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)  
CAUTION  
: LEAD FREE MARK  
Use of controls or adjustments or performance of procedures  
other than those specified herein may result in hazardous ra-  
diation exposure.  
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 flow) than  
ordinary solder so use caution not to let solder bridges occur  
such as on IC pins, etc.  
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.  
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).  
• Usable with ordinary solder  
• Be careful not to apply force on the conductor when soldering  
or unsoldering.  
It is best to use only unleaded solder but unleaded solder may  
also be added to ordinary solder.

TEST MODE  
Outline  
Operation in Setting the Test Mode  
• When the test mode becomes active, first the display check mode  
is selected.  
• Other mode can be selected from the display check mode.  
• When the test mode is set, the LCD repeats the following dis-  
play.  
• This set provides the Overall adjustment mode that allows CD  
and MO discs to be automatically adjusted when in the test mode.  
In this overall adjustment mode, the disc is discriminate between  
CD and 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 individual adjustment to be auto-  
matically adjusted.  
Remote commander LCD display  
• Operation in the test mode is performed with the set. A key  
having no particular description in the text, indicates a set key.  
• For the LCD display, the LCD on the remote commander is  
shown, but the contents of LCD display on the set are same.

Setting Method of Test Mode  
There are two different methods to set the test mode:  
1 Short SL801 (TEST) on the MAIN board with a solder bridge  
(connect pin 3of IC801 to the ground) and turn on the [HOLD]  
switch. Then, turn on the power.  
All off

003 : US, Canadian models  
• When the X key is pressed and hold down, the display at that  
time is held so that display can be checked.  
Caution: On the set having the microcomputer version 1.000,  
some adjusted values were set in the manual mode at  
the shipment, but these data will be cleared when the  
NV is reset. Therefore, on the set having the micro-  
computer version 1.000, change the adjusted values  
following the Change of Adjusted Values immediately  
after the NV was reset (see page 18).  
Releasing the Test Mode  
For test mode set with the method 1:  
Turn off the power and open the solder bridge on SL801 (TEST)  
on the MAIN board.  
Note: Remove the solders completely. Remaining could be shorted with  
S801 [HOLD] switch

Self-Diagnosis Result Display Mode  
This set uses the self-diagnostic function system in which if an  
error occurred during the recording or playing, the mechanism  
control block and the power supply control block in the  
microcomputer detect it and record its cause as history in the  
nonvolatile memory.  
• Address & Adjusted Value Display  
By checking this history in the test mode, you can analyze a fault  
and determine its location.  
Remote commander LCD display  
Total recording time is recorded as a guideline of how long the  
optical pickup has been used, and by comparing it with the total  
recording time at the time when an error occurred in the self-  
diagnosis result display mode, you can determine when the error  
occurred.

Caution:  
• C : panel designation.  
Pattern face side: Parts on the pattern face side seen from

Note: The components identified by mark 0 or dotted line  
with mark 0 are critical for safety.

• MAIN board is four-layer printed board.  
However, the patterns of layers 2 and 3 have not been  
included in this diagrams.  
• A : B+ Line.  
• Total current is measured with MD installed.  
• Power voltage is dc 3 V and fed with regulated dc power  
supply from external power voltage jack.  
• Voltages and waveforms are dc with respect to ground in  
playback mode.
