50WV or less are not indicated except for electrolytics and
tantalums.
All electrolytics are in 50V unless otherwise specified.
All variable and adjustable resistors have characteristic
curve B. unless otherwise noted.
-m-:
nonflammable resistor.
• ~ : fusible resistor.
c=J:
panel designation and adjustment for repair.
/::,.
: internal component.
The components identified by
B
in this basic schematic
diagram· have been carefully factory-selected for each set
in order to satisfy regarding X-ray radiation.
Should replacement be required. replace only with the
value originally used.
• When replacing components identified by
~
• make the
necessary adjustments indicated. If results do not meet
the specified value. change the component identified by
B
and repeat the adjustment until the specified value is
achieved. (Refer to RV402 adjustments on page 17.)
When replacing the part in below table. be sure to
perform the related adjustment.

Circled numbers refer to waveforms.
All voltages are in V.
Voltages are dc with respect to ground unless otherwise
noted.
Reading are taken with a color·bar signal input.
(DIGITAL VIDEO GENERATOR H: 31.47kHz. V : 70.1 Hz)
Readings are taken with a 10M 0 digital multi meter.
Voltage variations may be noted due to normal produc·
tion tolerances.
Can not be measured .
