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.

f

: nonflammable resistor.

F

: 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.

• 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.

• 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.

Note: The components identified by shading and mark

!

are critical for safety. Replace only with part

number specified.

Divided circuit diagram

One sheet of D board circuit diagram is divided into four

sheets, each having the code D-

d

. For example, the

destination ab1 on the D-

a

sheet is connected to ab1 on the

D-
