3-4. 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.
•
: 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.
