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 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 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 Section 2: Safety Releated Adjustments.)
When replacing the parts listed in the table below, it is important to
