Note:
. . . . . Parts marked " * " differ according to the model/destination. Refer
to the mount table for each function.
. . . . . The parts marked " # " on schematic diagrams are not mounted.
. . . . . All capacitors are in µF unless otherwise noted. pF: µµF 50WV or
less are not indicated except for electrolytics.
. . . . . All electrolytics are in 50 V unless otherwise specified.
. . . . .
: fusible resistor
. . . . .
: nonflammable resistor
. . . . .
: internal component
. . . . .
: panel designation and adjustment for repair
. . . . . Caution when replacing chip parts
New parts must be attached after removal of the chip.
Be careful not to heat the minus side of a tantalum capacitor,
because it is easily damaged by the heat.

• The components marked
in this schematic diagram have been
carefully factory-selected for each set in order to satisfy regulations
regarding X-ray radiation.
• When replacing components marked
, make the necessary
adjustments indicated. If results do not meet the specified value,
change the component marked
and repeat the adjustment until
the specified value is achieved.
• When replacing a part shown in the table below, be sure to perform
the related adjustment.

[Measuring conditions, voltage and waveform]
. . . . . A voltage value is the reference value between the measurement
point and the earth, when the NTSC color bar signal and RGB
color bar signal are received from the HD color bar generator (digital
multi-meter used: 10 M ohms/V DC).
. . . . . Unit of voltage is V (volt).
. . . . .
: B+line
. . . . .
: B– line
. . . . . Voltage variations may occur due to normal production tolerances.
. . . . . RGB color bar signal.
. . . . .
: Measurement disabled.
• Circled numbers indicate the reference waveform.
: Signal path.
The components identified marked ! are
critical for safety.
Replace only with the part number specified.
Les composants identifiés par la marque !
sont critiques pour la sécurité.
Ne les remplacer que par une pièce portant
le numéro spécifié.
NOTE:
The circuit indicated as shown on the left contains
high voltages of over 600 Vp-p. Take care to avoid
electric shock during inspection or repair work.
