Printed Wiring Boards And Schematic Diagrams; Ma10 (1/3) Board - Sony TRINITRON KV-VF14M70 Service Manual

5-3. PRINTED WIRING BOARDS AND
SCHEMATIC DIAGRAMS
Note:
• All capacitors are in µF unless otherwise noted. pF: µµF
Capacitors without voltage indication are all 50V.
• All resistors are in ohms.
kΩ = 1000Ω, MΩ = 1000kΩ
• Indication of resistance, which does not have one for rating electrical
power, is as follows.
Pitch: 5 mm
Rating electrical power: 1/4W(CHIP:1/10W)
•
: nonflammable resistor.
•
: fusible resistor.
• f
: internal component.
•
: panel designation and adjustment for repair.
• All variable and adjustable resistors have characteristic curve B, unless
otherwise noted.
•
: earth-chassis.
• Readings are taken with a color-bar signal input.
• Readings are taken with a 10MΩ digital multimeter.
• Voltage variations may be noted due to normal production tolerances.
• All voltages are in V.
no mark : REC/PB
( ) : REC
< > : PB
• Circled numbers are waveform reference.
•
: B + line
V
•
V : B – line.
÷
•
: signal path.
