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.
•
f
: 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.
• 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 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 spécifié.
