9-2. SCHEMATIC DIAGRAMS/PRINTED WIRING BOARDS
Note:
All capacitors are in µF unless otherwise noted.
•
50WV or less are not indicated except for electrolytics.
pF: µµF
• Indication of resistance, which does not have one for rating
electrical power, is as follows.
Pitch: 5 mm
Rating electrical power 1/4W
• Chip resister are 1/10W unless otherwise noted.
• All resistors are in ohms. (MΩ = 1000KΩ, KΩ = 1000Ω)
• : nonfiammable resistor.
• : fusible resistor.
• ¢ : internal component.
• : panel designation and adjustment for repair.
• All variable and adjustable resistors have characteristic curve B,
unless otherwise noted.
• METAL FILM (: RN) resister in 0.5% or 1%, 1/4W unless otherwise
specified.
• All voltages are in V.
• Voltage variations may be noted due to normal production tolerance.
• Reading are taken with Composite Video and Component (R.G.B.
HD, VD) color-bar signal input from color-bar pattern generator.
• Voltage are dc with respect to ground unless otherwise noted.
• no mark: Composite Video signal and comon
( ) : Component (R.G.B. HD, VD) signal (QA Board)
• : B+/B– line.
V
• : signal path.
• Circled numbers are waveforms reference.
• # : not use.
