3-3. 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.
• : nonfl ammable 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.
Note: The components identified by shading and
mark are critical for safety. Replace only
with part number specifi ed.
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 spécifi é.
