Printed Wiring Boards
Note:
• All capacitors are in µF unless otherwise noted. pF: µµF 50WV or
less are not indicated except for electrolytics.
• All electrolytics are in 50 V unless otherwise specified.
• : fusible resistor
• : nonflammable resistor
• : internal component
• : panel designation and adjustment for repair
• Caution when replacing chip parts
New parts must be attached after removal of the chip.
Be careful not to heat the minus side of a tantalum capacitor,
because it is easily damaged by the heat.

[Measuring conditions, voltage and waveform]
• A voltage value is the reference value between the measurement
point and the earth, when the NTSC color bar signal is received
from the color bar generator (digital multi-meter used: 10 M ohms/
V DC).
• Unit of voltage is V (volt).
• : B+line
: B– line
• Voltage variations may occur due to normal production tolerances.
• : Measurement disabled.
• Circled numbers indicate the reference waveform.
• : Signal path.
