Printed Wiring Boards And Schematic Diagrams; Ma10 (1/3) Board - Sony TRINITRON KV-VF21M40 Service Manual

5-3. PRINTED WIRING BOARDS AND
SCHEMATIC DIAGRAMS
Note:
All capacitors are in F unless otherwise noted. pF: F
Capacitors without voltage indication are all 50V.
All resistors are in ohms.
k = 1000 , M = 1000k
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 10M 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.
