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.
SECTION 5: DIAGRAMS
The components identifi ed by shading and
!
symbol are critical for safety. Replace only with
part number specifi ed.
The symbol
indicates a fast operating fuse
and is displayed on the component side of the
board. Replace only with fuse of the same rating
as marked.
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.
: 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 10M digital multimeter.
Voltages are DC with respect to ground unless otherwise noted.
Voltage variations may be noted due to normal production tolerances.
