NOTE:
The circuit indicated as left contains high voltage of over
600 Vp-p. Care must be paid to prevent an electric shock in
inspection or repairing.

Note: The components identified by shading and mark

are critical for safety. Replace only with part

number specified.

• 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.

•

: B + bus.

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.

•

: 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

]

, make the

necessary adjustments indicated. (See page 3-1)

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

related adjustment.
