Note:
•
All capacitors are in 
µ
F unless otherwise noted. (pF:  
µµ
F)
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.
•
: nonflammable resistor.
•
: fusible resistor.
•
 T
: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 
]
, 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
Ω
 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.
•
: B + bus.
•
: B – bus.
4-3. SCHEMATIC  DIAGRAMS  AND  PRINTED  WIRING  BOARDS
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 A, U boards circuit diagrams are divided into two
sheets, each having the code A-P1-
