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.
•
T
: 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

Divided circuit diagram
Schematic diagrams of A, MS, P, TU and U boards are divided into
serveral pieces. Information to where the line is to be connected is printed
at the end of wach line.
For example, [ TO A1/12, A2/12_1 ] means the line is connected to
Ref. No. 1 of A (1/12) and A (2/12) schematic diagrams.
Ref. No.
