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

Note: In this set, the SERVO board has been changed 

in the midway of production.

 

Printed wiring boards, schematic diagrams and 
electrical parts list of the SERVO board that 
have been described to this service manual 
are information before it is changed.

 

Refer to supplement-1 for the SERVO board 
after it changes.

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.

The laser diode in the optical pick-up block may suffer electrostat-
ic 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.

EXTENSION  CABLE  AND  SERVICE  POSITION
When repairing or servicing this set, connect the jig (extension cable) as shown below.

•  Connect the MAIN board (CN101) and the SERVO board (CN3) with the extension cable (Part No. J-2502-062-1). 

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  THE  IC4  ON  THE  SERVO  BOARD  
REPLACING
IC4 on the SERVO board cannot exchange with single. When this 
part is damaged, exchange the entire mounted board.

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 1: In this set, the SERVO board of two types exists. Repair after 

distinguishing which type set of the repair referring to supple-
ment-1.

Note 2: When soldering the short lands, solder within 5 seconds at the 

temperature 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  THE  MOUNTED  MAIN  
BOARD
If the mounted MAIN board was replaced, be sure to refer to Tech-
nical News published separately.
