Note 1:
Refer to the servicing notes “MAIN BOARD
DISCRIMINATION” (page 5) for how to distinguish
SUFFIX-11 and SUFFIX-12.
Note 2:
A part of circuit composition of MAIN board (Suf
fi
x-12) has been changed in the
midway of production. MAIN board (Suf
fi
x-12) that has not been changed appears
as TYPE A, and the changed MAIN board (Suf
fi
x-12) appears as TYPE B.
Note 3:
IC103 and C242 (Combination: TYPE B) on the MAIN board (Suf
fi
x-12) cannot exchange
with single. When these parts on the MAIN board (Suf
fi
x-12) are damaged, remove IC103
and C242 (Combination: TYPE B) and replace with IC102 and C239 (Combination: TYPE A).
