7-3. CIRCUIT BOARDS LOCATION
Note:
• The parts marked “#” on schematic diagrams are not mounted.
• 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.
• 5 : 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.
• 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.
•
F
: Signal path.
• The components identified by
[
in this basic schematic diagram
have been carefully factory-selected for each set in order to
satisfy regulations regarding X-ray radiation.
Should replacement be required, replace only with the value
originally used.
• When replacing components identified by
]
, make the
necessary adjustments indicated. (See page 51)
• When replacing the part in below table, be sure to perform the
related adjustment.

Divided schematic diagram
Schematic diagrams of A, AD, B, D, G and K boards are divided
into several pieces. Information to where the line is to be connected
is printed at the end of each line.
For example, [ TO A1/3,A2/3_1 ] means the line is connected to
Ref. No. 1 of A (1/3) and A (2/3) schematic diagrams.
TO A1/3,A2/3_1
Ref. No.
