All capacitors are in µF unless otherwise noted. pF : µµF 50WV or
less are not indicated except for electrolytics and tantalums.
All electrolytics are in 50V unless otherwise specifi ed.

: nonfl ammable 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 identifi ed by shading and
!
symbol are critical for safety. Replace
only with part number specifi ed.
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.
Les composants identifi es per un trame et une marque

sont critiques pour la
securite. Ne les remplacer que par une piece portant le numero specifi e.
Le symbole
indique une fusible a action rapide. Doit etre remplace par une
fusible de meme yaleur, comme maque.
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.
When replacing the parts listed in the table below, it is important to
perform the related adjustments.
