SCHEMATIC DIAGRAMS INFORMATION
All capacitors are in µF unless otherwise noted. pF : µµF 50V or less are
not indicated except for electrolytics and tantalums.
All electrolytics are in 50V unless otherwise speciﬁ ed.
All resistors are in ohms. kΩ=1000Ω, MΩ=1000kΩ
Indication of resistance, which does not have one for rating electrical
power, is as follows:
Pitch : 5mm
Rating electrical power :
W in resistance,
: nonﬂ ammable resistor
: fusible resistor
: internal component
: panel designation and adjustment for repair
: earth ground
All variable and adjustable resistors have characteristic curve B, unless
Readings are taken with a color-bar signal input.
Readings are taken with a 10MΩ 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 impossibility.

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 R562 adjustment on page 15.)
When replacing the parts listed in the table below, it is important to
perform the related adjustments.
