STANDARD CIRCUIT DIAGRAM

NOTE ON USING CIRCUIT DIAGRAMS

1.SAFETY

The components identified by the symbol and shading are
critical for safety. For continued safety replace safety critical
components only with manufactures recommended parts.

2.SPECIFIED VOLTAGE AND WAVEFORM VALUES

The voltage and waveform values have been measured under the
follo win g c onditions.

(1)Input signal : Colour bar signal

(2)Setting positions of
each knob/button and
variable resistor

(3)Internal resistance of test er

:DC 20k

/V

(4)Oscilloscope sweeping time

:H

20µS/div

:V

5mS/div

:Others

Sweeping time is
specified

(5)Voltage values

:All DC voltage values

Since the voltage values of signal circuit vary to some extent
according to adjustments, use them as reference values.

5.N OT E FOR RE PAIRIN G SERVICE

This mod el's power cir cuit is pa rtly diffe rent in the GND. The
difference of the GND is shown by the LIVE : ( ) side GND and the
ISOLATED(NEUTRAL) : ( ) side GND.Therefore, care must be
taken for the following points.

(1)Do not touch the LIVE side GND or the LIVE side GND and the
ISOLATED(NEUTRAL) side GND simultaneously. If the above
caution is not respected, an electric shock may be caused.
Therefore, make sure that the power cord is surely removed from
the receptacle when, for example, the chassis is pulled out.

(2)Do not short between the LIVE side GND and ISOLATED(NEUTRAL)
side GND or never measure with a measuring apparatus measure
with a measuring apparatus ( oscilloscope, etc.) the LIVE side GND
and ISOLATED(NEUTRAL) side GND at the same time.
If the above precaution is not respected , a fuse or any parts will be broken.

Since the circuit diagram is a standard one, the ci rcuit and
circuit constants may be subject to change for i mprovement
without any not ic e.

NOTE
Due improvement in performance, some part numbers show
in th e ci rcui t diag ram may not agre e wi th tho se i ndic ate d i n
the part list.
When ordering parts, pl ease use t he numbers t hat appear
in the Parts List.
