SCHEMATIC DIAGRAMS INFORMATION
All capacitors are in µF unless otherwise noted. pF : µµF 50WV or less
are not indicated except for electrolytics and tantalums.
All electrolytics are in 50V unless otherwise specifi ed.
All resistors are in ohms. kΩ=1000Ω, MΩ=1000kΩ
Indication of resistance, which does not have one for rating
electrical power, is as follows:
Rating electrical power :
1 1
/ W in resistance, / W and
4 10
: nonfl ammable resistor
: fusible resistor
: internal component
: panel designation and adjustment for repair
: earth ground
: earth-chassis
All variable and adjustable resistors have characteristic curve B,
unless otherwise noted.
Readings are taken with a color-bar signal input.
Readings are taken with a 10MΩ digital multimeter.
Voltages are DC with respect to ground unless otherwise noted.
Voltage variations may be noted due to normal production
tolerances.
All voltages are in V.
S : Measurement impossibility.
: B+line.
: B-line. (Actual measured value may be different).
: signal path. (RF)
Circled numbers are waveform references.

The components identifi ed by X in this basic schematic
diagram have been carefully factory-selected for each set
in order to satisfy regulations regarding X-ray radiation.
Should replacement be necessary, replace only with the

value originally used.
When replacing components identifi ed by Y, make the
necessary adjustments as indicated. If the results do not
meet the specifi ed value, change the component identifi ed
by X and repeat the adjustment until the specifi ed value is
achieved.
When replacing the parts listed in the table below, it is important to
perform the related adjustments.
