Note:
. . . . . Parts marked " * " differ according to the model/destination. Refer
to the mount table for each function.
. . . . . 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, be-
cause 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 regula-
tions regarding X-ray radiation.
• When replacing components marked , make the necessary ad-
justments 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 per-
form the related adjustment.

[Measuring conditions, voltage and waveform]
. . . . . A voltage value is the reference value between the measurement
point and the earth, when the SECAM color bar signal and RGB
color bar signal are received from the color bar generator (digital
multi-meter used: 10 M ohms/V DC).
. . . . . Unit of voltage is V (volt).
(Voltage variations may occur due to normal production tolerances.)
. . . . .
: B line
. . . . . No mark : SECAM (3.58 MHz) color bar signal.
. . . . .
: Measurement disabled.
. . . . . : 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.
