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.

[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 (100%) is
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
. . . . . : B– line
. . . . . No mark : NTSC (3.58 MHz) 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.
