5-2. PRINTED WIRING BOARDS AND
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 speciÞ 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
Rating electrical power :
/ W in resistance, / W and

: nonß ammable resistor.
: fusible resistor.
: internal component.
: panel designation and adjustment for repair.
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.
V
: B-line. (Actual measured value may be different).
: signal path. (RF)
Circled numbers are waveform references.

The components identiÞ ed by shading and
only with part number speciÞ 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 identiÞ es per un trame et une marque
securite. Ne les remplacer que par une piece portant le numero speciÞ e.
Le symbole indique une fusible a action rapide. Doit etre remplace par une
fusible de meme yaleur, comme maque.
The components identiÞ 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 identiÞ ed by Y, make the necessary
adjustments as indicated. If the results do not meet the speciÞ ed value,
change the component identiÞ ed by X and repeat the adjustment until
the speciÞ ed value is achieved.
(Refer to R564 Adjustment on page 15.)
When replacing the parts listed in the table below, it is important to
perform the related adjustments.
