The components identied by shading and ! symbol are critical for safety. Replace
only with part number speci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 identies per un trame et une marque ! sont critiques pour la
securite. Ne les remplacer que par une piece portant le numero specie.
Le symbole indique une fusible a action rapide. Doit etre remplace par une
fusible de meme yaleur, comme maque.

SCHEMATIC DIAGRAM 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 specied.
All resistors are in ohms. kΩ=1000Ω, MΩ=1000kΩ
Indication of resistance, which does not have one for rating electrical
power, is as follows: Pitch : 5mm

: non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 10MΩ 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 impossibillity.
: B+line.
: B-line (Actual measured value may be different).
: signal path (RF).
Circled numbers are waveform references.
The components identi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 identied by Y , make the necessary
adjustments as indicated. If the results do not meet the specied value,
change the component identied by X and repeat the adjustment until
the specied value is achieved.
(Refer to Section 2: Safety Releated Adjustments.)
When replacing the parts listed in the table below, it is important to
perform the related adjustments.
