SECTION 1  
SERVICING NOTE  
• 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 8)  
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.

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  
MAIN board  
• Replacement of CDX2671-204GA (IC801) used in this set  
requires a special tool.  
• 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 microcomputer version 1.000, change the  
adjusted values following the Change of Adjusted 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)

TEST MODE  
4-1. Outline  
4-3. 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.  
This set 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 set is shown.

4-2. 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 3 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.  
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).  
4-4. 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 the chassis, etc.  
For test mode set with the method 2:  
Turn off the power.  
Note: If electrical adjustment (see page 18) has not been finished  
completely, always start in the test mode. (The set cannot  
start in normal 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.

Memory was Replaced  
When the microcomputer in this set is replaced with a different  
version of microcomputer, it is needed to initialize the modified  
program data in the nonvolatile memory and write specific modi-  
fied data for the new version in the memory.  
If the microcomputer is replaced with a different version, the patch  
data should be rewritten as performed when the nonvolatile memory  
is replaced.  
For a version where the method to write patch data is not described,  
the modified data should be initialized as specified below:

number in the exploded views are not supplied.  
• Items marked “*” are not stocked since  
they are seldom required for routine service.  
Some delay should be anticipated

ELECTRICAL PARTS LIST  
NOTE:  
• Due to standardization, replacements in  
the parts list may be different from the  
parts specified in the diagrams or the  
components used on the set.  
• -XX and -X mean standardized parts, so  
they may have some difference from the  
original one.  
• Items marked “*” are not stocked since  
they are seldom required for routine service.  
Some delay should be anticipated  
when ordering these items.  
• SEMICONDUCTORS  
In each case, u : µ, for example:  
uA.. : µA.. uPA.. : µPA..
