Accessories are given in the last of the electrical parts list.

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 fl exible 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.

If the optical pick-up block is defective, please replace the whole 
optical pick-up block.
Never turn the semi-fi xed resistor located at the side of optical 
pick-up block.

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)

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 fl ow) 
than ordinary solder so use caution not to let solder bridges 
occur such as on IC pins, etc.

• 

Usable with ordinary solder

 

It is best to use only unleaded solder but unleaded solder may 
also be added to ordinary solder.

NOTE  FOR  REPLACEMENT  OF  THE  USB  CONNEC-
TOR (CN971)  AND  THE  AUX  JACK (J901)
To replace the USB connector and the AUX jack requires align-
ment.
1.  Insert the USB connector and the AUX jack into the front pan-

el.

2.  Place the KEY board on the front panel and align the terminals 

of the USB connector and the AUX jack with the holes in the 
KEY board.

3.  Solder four terminals of the connector and three terminals of 

the jack.

TEST  DISCS
Use following TEST DISC when this set confi rms the operation 
and checks it.

Part No.

NOTE  FOR  THE  20-PIN  CONNECTOR (CN901)
Do not use alcohol to clean the 20-pin connector (CN901) connect-
ing the front panel with the main body.
Do not touch the connector directly with your bare hand. Poor con-
tact may be caused.

NOTE  FOR  REPLACEMENT  OF  THE  SERVO  BOARD
When repairing, the complete SERVO board should be replaced 
since any parts in the SERVO board cannot be repaired.

NOTE  FOR  REPLACEMENT  OF  THE  SENSOR  BOARD
When SENSOR board is defective, exchange the MECHANICAL 
BLOCK ASSY (P).

EXTENSION  CABLE  AND  SERVICE  POSITION
When repairing or servicing this set, connect the jig cable (exten-
sion cable (CD mecha)) as shown below.

•  Connect the MAIN board (CN701) and the SERVO board 

(CN401) with the jig cable.
