SCHEMATIC DIAGRAMS AND PRINTED WIRING BOARDS

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.
• : nonflammable resistor.
• : fusible resistor.
• : internal component.
• : panel designation, and adjustment for repair.
• All variable and adjustable resistors have characteristic curve
B, unless otherwise noted.
• : earth-ground.
• : 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.
• : Names and values of parts depend on models.
*
• : Can not be measured.
*
• Circled numbers are waveform references.
• : B + bus.
• : B – bus.
• : Signal path.
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.
