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.

[Measuring conditions, voltage and waveform]
• A voltage value is the reference value between the measurement
point and the earth, when the RGB color bar signal is received
from the 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.
• 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.
