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 specified.
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 :
/ W in resistance, / W and

4 10
: nonflammable 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 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.

Circled numbers are waveform references.
The components identified 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 identified by Y, make the necessary
��
adjustments as indicated. If the results do not meet the specified value,
change the component identified by X and repeat the adjustment until
the specified 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.
