5-2. PRINTED WIRING BOARD AND
SCHEMATIC DIAGRAM 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. k=1000, M=1000k
Indication of resistance, which does not have one for rating electrical
power, is as follows: Pitch : 5mm Rating electrical power :
1
/
4
W in resistance,
1
/
10
W and
1
/
8
W in chip resistance.
: nonfl ammable resistor.
: fusible resistor.
: internal component.
: panel designation and adjustment for repair.
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 10M 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 impossibillity.
: 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. (Refer to Safety Related Adjustments
on Page 15.)
When replacing the parts listed in the table below, it is important to
perform the related adjustments.
