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

•
: 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-chassis.
• When replacing the part in below table, be sure to perform the
related adjustment.
• Readings are taken with a color-bar signal input.
No mark: PAL
<
>: SECAM
(
): NTSC 3.58
• 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.
•
: B+ line
•
: B– line
(Actual measured value may be different)
•
: signal path
• Circled numbers are waveform references.
