6-2. Schematic Diagrams and
Board Layouts
Note:
. . . . . The parts marked " # " on schematic diagrams are not mounted.
. . . . . 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
. . . . . : 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, be-
cause 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 RGB 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.
. . . . .
: Signal path.
