SCHEMATIC DIAGRAMS
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 :

: 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
Ω
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 identified by shading and
!
symbol are critical for safety.
Replace only with part number specified.
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.
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 (Refer
to Safety Related Adjustments on page 33).
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.
