Note:
• All capacitors are in µF unless otherwise noted. pF: µµF 50WV or less are
not indicated except for electrolytics.
• All electrolytics are in 50V unless otherwise specified.
All resistors are in ohms, 1/4W in resistance, 1/10W in chip resistance.
k!l= 1 ooon. Mil= 1 0001<n
m. : nonflammable resistor.
•
~
: fusible resistor.
6 : internal component.
c=J : panel designation and adjustment for repair.
All variable and adjustable resistors have characteristic curve B, unless
otherwise noted.
The components identified by
R 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 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 H and repeat the adjustment until the
specified value is achieved. (Refer to R1535, R1536 adjust on Page 36 .)
When replacing the part in below table,
be sure to perform the related
adjustment.
