SCHEMATIC DIAGRAMS INFORMATION
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.
