*

• 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

cifié.

5-3. SCHEMATIC  DIAGRAMS  AND

PRINTED  WIRING  BOARDS

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.

•

¢

: 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 3-1)

• When replacing the part in below table, be sure to perform the

related adjustment.
