Note:
• All capacitors are in µF unless otherwise noted. pF: µµF 50
WV or less are not indicated except for electrolytic.
• Indication of resistance, which does not have one for rating
electrical power, is as follows.
Pitch: 5 mm
Rating electrical power 1/4 W (CHIP: 1/10 W)
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 otherwise noted.
: earth-ground
: earth-chassis.
• The components identified by
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 required, replace only with the value
originally used.
• When replacing components identified by
necessary adjustments by using RV501 ( ) as indicated.
(See page 14)
Note: The components identified by shading and
mark
are critical for safety. Replace only with
part number specified.
Note: Les composants identifies per un trame et une
marque
sont critiques pour la securite. Ne les
remplacer que par une piece portant le numero specifie.
