(KV-32S66/32V42/35S66/35V42 ONLY)
6-4. PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS
• 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 specified.
• All resistors are in ohms.

: nonflammable resistor.
•
: fusible resistor.
•
: internal component.
•
: panel designation and adjustment for repair.
• All variable and adjustable resistors have characteristic curve B, unless oth-
erwise noted.
• The components identified by
in this basic schematic diagram have been
carefully factory-selected for each set in order to satisfy regulations regard-
ing X-ray radiation.
Should replacement be required, replace only with the value originally used.
• When replacing components identified by
, make the necessary adjust-
ments indicated. If results do not meet the specified value, change the com-
ponent identified by
and repeat the adjustment until the specified value is
achieved. (Refer to R530 and R531 adjustment on Page 15.)
• When replacing the part in below table, be sure to perform the related adjust-
ment.
• 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 impossibillity.

: B-line.
(Actual measured value may be different).
•
: signal path. (RF)
• Circled numbers are waveform references.

Les composants identifiés per un tramé et une marque sont
critiques pour la sécurité. Ne les remplacer que par une piéce
portant le numéro spécifié.
Le symbole
indique une fusible a action rapide. Doit etre
remplacee par une fusible de meme yaleur, comme maque.
The symbol
display is on the component side. The
components identified by shading and mark are critical for
safety. Replace only with part number specified.
The symbol
indicate fast operating fuse. Replace only
with fuse of same rating as marked.
