SCHEMATIC NOTES
1. Resistors are carbon 1/4W unless noted
otherwise.
2. Capacitors are ceramic 50V unless noted
otherwise.
3. Coil value notes is inductance in
µ
H.
4. Test point indicated by
; Test point but no
pin .
5. Components indicated with
are critical
parts and replacement should be made
with manufacture specified replacement
parts only.
6.
(BOLD LINE) indicates the route
of B+ supply.
7. The schematic diagrams are current at
the time of printing and are subject to
change without notice.
8. Ground
symbol
indicates
HOT
GROUND
CONNECTION;
indicates COLD GROUND.
NOTE: All other component symbols are
used
for
engineering
design
purposes.
WAVEFORM MEASUREMENTS
1.
indicates
waveform
measurement.
(Measurement can be taken at the best
accessible location in common to the
indicated point.)
2. Taken
with an NTSC
signal generator
connected
to
the
antenna
terminal.
(NTSC color bar pattern of 8 bars of EIA
colors, 100 IRE white and 7.5 IRE black.)
3. Customer Controls (Picture/Audio Menu) are
set to Normalize. Volume is set to “MIN”.
4. All video and color waveforms are taken
with a wideband scope and a probe
with low capacitance (10 to 1). Shape
and
peak
altitudes
may
vary
depending on the type of Oscilloscope
used and its settings.
5. Ground symbol
shown on waveform
number indicates (Hot) ground lead
connection of the Oscilloscope.
CAUTION: Incorrect ground connection of
the test equipment will result in erroneous
readings.

VOLTAGE MEASUREMENTS
1. Voltage measurement:
-
AC input to the Receiver is 120V.
NTSC (HD, 1125i & 525P when
applicable)
signal
generator
is
connected to the antenna of the
Receiver. (Color bar pattern of 100
IRE white and 7.5 IRE black.)
-
All Picture and Audio adjustments are
set to Normalize.
TV ANT/CABLE - (Set-Up Menu) in
TV/ANT Mode
Volume - Min.
TV/Video SW - TV position
Audio Mode - Stereo
-
Voltage readings are nominal and
may vary ±10% on active devices.
Some voltage reading will vary
with signal strength and picture
content.
-
Supply voltages are nominal.
2. Ground symbol
indicates ground lead
connection of meter.
Incorrect ground connection will result
in erroneous readings.
CAUTION: Incorrect ground connection
of the test equipment will result in
erroneous readings.
