Note:
• All capacitors are in µF unless otherwise noted. (pF: µµF)
Capacitors without voltage indication are all 50 V.
• Indication of resistance, which does not have one for rating
electrical power, is as follows.
Pitch: 5 mm
Rating electrical power 1/4 W (CHIP : 1/10 W)
• All resistors are in ohms.
f
• : nonflammable resistor.
Ï
• : fusible resistor.
¢
• : internal component.
p
• : panel designation, and adjustment for repair.
• All variable and adjustable resistors have characteristic curve B,
unless otherwise noted.
e
• : earth-ground.
E
• : earth-chassis.
• The components identified by
have been carefully factory-selected for each set in order to
satisfy regulations regarding X-ray radiation.
Should replacement be required, replace only with the value
originally used.
• When replacing components identified by
necessary adjustments indicated. (See page 3-1)
• When replacing the part in below table, be sure to perform the
related adjustment.

• All voltages are in V.
• Readings are taken with a 10 M digital multimeter.
• Readings are taken with a color-bar signal input.
• Voltage variations may be noted due to normal production
tolerances.
*
• : Can not be measured.
• Circled numbers are waveform references.
s
• : B + bus.
S
• : B – bus.

Note: The components identified by shading and mark
¡
are critical for safety. Replace only with part
D
number specified.
Note: Les composants identifiés par un tramé et une
¡
marque sont critiques pour la sécurité. Ne les
remplacer que par une pièce portant le numéro
