Note:
• Capacitors without voltage indication are all 50V.
• All resistors are in ohms.
kΩ=1000Ω, MΩ=1000kΩ
• Indication of resistance, which dose not have one for rating electrical power, is
as follows.
Pitch : 5mm
Rating electrical power : 1 /
•
: nonflammable resistor.
• : fusible resistor.
• : internal component.
• : panel designation and adjustment for repair.
• All variable and adjustable resistors have characteristic curve B, unless otherwise
noted.

• The components identified by
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
indicated. If results do not meet the specified value, change the component
identified by and repeat the adjustment until the specified value is achieved.
(Refer to R514,R561 and C514 adjustment on Page xx – xx.)
• When replacing the part in below table, be sure to perform the related adjustment.

• As to the voltage volue shown by the semiconductors on the Shematic Diagram,
see the another list
• Readings are taken with a color-bar signal input.
• Readings are taken with a 10MΩ digital multimeter.
• Voltages are dc with respect to ground unless otherwise noted.
• Voltage variations may be noted due to normal production tolerances.
• All voltages are in V.
* : Measurement impossibillity.
• Circled numbers are waveform references.
• : B+ bus.
