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 soldering iron around 270 °C during 
repairing.
• 
Do not touch the soldering iron on the same conductor of the 
circuit board (within 3 times).
• 
Be careful not to apply force on the conductor when soldering 
or unsoldering.

SECTION  1
SERVICING  NOTES
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.
NOTE  ON  LASER  DIODE  EMISSION  CHECK
The laser beam on this model is concentrated so as to be focused 
on the disc refl ective surface by the objective lens in tha optical 
pick-up block. Therefore, when checking the laser diode emission, 
observe from more than 30 cm away from the objective lens.
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)
 : LEAD  FREE  MARK
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  THE  IC4,  IC11  AND  IC13  ON  THE  SERVO  
BOARD  REPLACING
IC4, IC11 and IC13 on the SERVO board cannot exchange with 
single. When these parts are damaged, exchange the entire mount-
ed board.
NOTE  FOR  REPLACING  THE  COMPLETE  MAIN  
BOARD
If the complete MAIN board was replaced, be sure to refer to Tech-
nical News published separately.
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  FLEXIBLE  BOARD  OF  THE  OPTICAL  
PICK-UP
When connecting or disconnecting the fl exible board of the opti-
cal pick-up to or from the CN2 of the SERVO board, follow the 
procedure given below.
Note: When soldering the short lands, solder within 5 seconds at the tem-
perature of soldering iron below 300°C.
Disconnection:
1.  Solder two shortland.
2. Disconnect the fl exible board from the CN2 of the SERVO 
board.
Connection:
1. Connect 
the 
fl exible board to the CN2 of the SERVO board.
2.  Unsolder two shortland.

NOTE  FOR  REPLACING  OF  THE  USB  CONNECTOR 
(CN902)
To replace the USB connector requires alignment.
1.  Insert the USB connector into the front panel.
2.  Place the KEY board on the front panel and align the terminals 
of the USB connector with the holes in the KEY board.
