2-4. SCHEMATIC DIAGRAMS AND PRINTED WIRING BOARDS
Note:
•
Schematic diagrams and printed wiring boards of the specified boards for
board replacement service are not included in this section.
See Appendix of this manual if you need them.
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 MΩ 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: The components identified by mark
contain
confidential information.
Strictly follow the instructions whenever the
components are repaired and/or replaced.
