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
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 fl exible board is easily damaged and should be handled with 
care.
NOTES  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 the optical 
pickup 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)
IMPORTANT  NOTE  FOR  REPAIRING (XAV-72BT)
This unit contain individual information that the customer regis-
tered because it installs the Bluetooth function.
When repairing, the data that the customer registered might disap-
pear. Have the approval of the customer beforehand.
If any of the following parts was replaced, that data disappears.
•  Complete LCD board
•  IC1102 on the LCD board
• Initialize
Note: Exchanged old complete LCD board and old IC1102 are destroyed 
with the hammer, and throw away.
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  THE  IC1201  ON  THE  LCD  BOARD  REPLACING
IC1201 on the LCD board cannot exchange with single. When this 
part is damaged, exchange the entire mounted board.
NOTE  FOR  REPLACEMENT  OF  THE  KEY  BOARD
When repairing, the complete KEY board should be replaced since 
any parts in the KEY board cannot be repaired.
 : 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.
