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 specified.

: 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 color-bar signal input.
Readings are taken with a 10M
Ω
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.
: B+line
: B-line (Actual measured value may be different).
: signal path (RF)
Circled numbers are waveform references.

The components identified by shading and
!
symbol are critical for safety. Replace
only with part number specified.
The symbol
indicates a fast operating fuse and is displayed on the component
side of the board. Replace only with fuse of the same rating as marked.

sont critiques pour la
securite. Ne les remplacer que par une piece portant le numero specifie.
Le symbole
indique une fusible a action rapide. Doit etre remplace par une
fusible de meme yaleur, comme maque.
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 3: Safety Related
Adjustments on Page 16.)
When replacing the parts listed in the table below, it is important to
perform the related adjustments.
