P4819(E) 4-6
Note:
• All capacitors are in µF unless otherwise noted. (pF: µµF)
Capacitors without voltage indication are all 50 V.
• 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.
•
f : nonflammable resistor.
•
Ï : fusible resistor.
• f : internal component.
•
p : panel designation, and adjustment for repair.
• All variable and adjustable resistors have characteristic curve B, unless otherwise noted.
•
e : earth-ground.
• E : 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
], make the necessary adjustments indicated. (See page 2-1)
• When replacing the part in below table, be sure to perform the related adjustment.
• All voltages are in V.
• Readings are taken with a 10 M digital multimeter.
• Readings are taken with a color-bar signal input.
• Voltage variations may be noted due to normal production tolerances.
•
*
: Can not be measured.
• Circled numbers are waveform references.
•
s : B + bus.
•
S :B – bus.

Note: The components identified by shading and
mark ! are critical for safety. Replace only
with part number specified.
Note: Les composants identifiés par un tramé et
une marque ! sont critiques pour la
sécurité. Ne les remplacer que par une pièce
portant le numéro spécifié.
• Divided circuit diagram
One sheet of D board circuit diagram is divided into three sheets,
each having the code D-a to D-c. For example, the destination
ab1 on the code D-a sheet is connected to ab1 on the D-b sheet.
