5-2. PRINTED WIRING BOARDS AND 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. 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 / W in resistance, 1 / W and 1 /
4 10
: 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 NTSC 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 adjustments in Sections 3-1 and 3-2.)
When replacing the parts listed in the table below, it is important to
perform the related adjustments.
