SCHEMATIC DIAGRAMS INFORMATION
All capacitors are in µF unless otherwise noted. pF : µµF 50WV or less
are not indicated except for electrolytics and tantalums.
All electrolytics are in 50V unless otherwise speci

All variable and adjustable resistors have characteristic curve B, unless
otherwise noted.
Readings are taken with a color-bar signal input.
Readings are taken with a 10M
Ω
digital multimeter.
Voltages are DC with respect to ground unless otherwise noted.
Voltage variations may be noted due to normal production tolerances.
All voltages are in V.
S : Measurement impossibility.

The components identi
fi
ed by shading and

symbol are critical for safety. Replace
only with part number speci
fi
ed.
The symbol
indicates a fast operating fuse and is displayed on the component
side of the board. Replace only with fuse of the same rating as marked.

e.
Le symbole
indique une fusible a action rapide. Doit etre remplace par une
fusible de meme yaleur, comme maque.
The components identi
fi
ed by
X
in this basic schematic diagram have
been carefully factory-selected for each set in order to satisfy regulations
regarding X-ray radiation. Should replacement be necessary, replace
only with the value originally used.
When replacing components identi
fi
ed by
Y
, make the necessary
adjustments as indicated. If the results do not meet the speci
fi
ed value,
change the component identi
fi
ed by
X
and repeat the adjustment until
the speci
fi
ed value is achieved.
(Refer to R530 and R531 adjustment on page 16.)
When replacing the parts listed in the table below, it is important to
perform the related adjustments.
