Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be
damaged by heat.
Flexible Circuit Board Repairing
• Keep the temperature of the 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.

Notes on the AC power adaptor
• Use only the AC power adaptor and the 
USB adaptor supplied with the player. Do 
not use any other AC power adaptor since 
this may cause the player to malfunction.
• The player is not disconnected from the 
AC power source (mains) as long as it is 
connected to the wall outlet, even if the 
player itself has been turned off.
• If you are not going to use the player for a 
long time, be sure to disconnect the power 
supply. To remove the AC power adaptor 
from the wall outlet, grasp the adaptor plug 
itself; never pull the cord.

SECTION  1
SERVICING  NOTES
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 flow)
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.
Replacement of CXR704060-201GA (IC1003),
S1R72003BOOA100 (IC2001), CXR710160-211GH
(IC3001), CXD1616GH (IC7001), EDL1216CASA-10L-E
(IC7002) and SC901584EPR2 (IC9002) used in this set
requires a special tool.
When IC1101 and IC1102 (IC1102 is mounted only E, Hong
Kong, Taiwan, Korean, Chinese and Tourist models) are
damaged, exchange the new MAIN board for the MAIN board
which IC damaged.
