SERVICING NOTES
The laser diode in the optical pick-up block may suffer electrostatic
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.

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
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

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 viscou-s (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.

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

NOTE WHEN REPLACING IC1 AND R197 ON THE XA-123 BOARD
There are two types of IC1 on the XA-123 board. Because IC1 has the combination with R197, the type of IC1 is confirmed by following
FLASH/MASK Type Discrimination, and R197 is replaced at the same time if necessary. (Be sure to confirm the type of new IC1, because
the supplied type cannot be specified by situations of the service parts)
Also when replacing R197, it is replaced after the type of IC1 is confirmed.

Also when replacing R197, it is replaced after the type of IC1 is confirmed.
FLASH/MASK Type Discrimination
FLASH/MASK type can be discriminated by printing of IC1 on the XA-123 board.
