10-2. SCHEMATIC DIAGRAMS/PRINTED WIRING BOARDS
Note:
. All capacitors are in µF unless otherwise noted.
PF: 50 WV or less are not indicated except for electorlytics.
. All electrolytics are in 50 V unless otherwise specified.
. All resistors are in ohms, 1/4 W in resistance, 1/10 W in chip
resistance.
kZ = 100, MZ = 1000 kZ
. : nonflammable resistor.
. ¢ : internal component.
. : panel designation, or adjustment for repair.
. All variable and adjustable resistors have characteristic curve B,
unless otherwise noted.
. The “4-1. +B Voltage Check” and “4-2. Protection Circuit (Hold-down
circuit) Check” should always be performed when replacing the
following components (marked on the schematic diagram).
. Readings are taken with a color-bar signal input.
no mark : With PAL color-ber signal receved or common voltage.
( ) : With SECAM color-ber signal receved.
< > : With NTSC (3.58, 4.43) color-ber signal receved.
. Readings are taken with a 10 MZ digital multimeter.
. Voltage are dc with respect to ground unless otherwise noted.
. Voltage variations may be noted due to normal production
tolerances.
. All voltages are in V.
. Circled numbers are waveform reference.
. :B+ bus.
. :B_ bus.
. : signal path.
