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 manufac tures recommended parts.
2.SPECIFIED VOLTAGE AND WAVEFORM VALUES
The voltage and waveform values have been measured under the
following condit ions.
(1)Input signal : Colour bar signal
(2)Setting positions of
each knob/button and
variable resistor
(3)Internal resistance of tester
(4)Oscil loscope sweeping time
(5)Volt age values
Since the v oltage values of si gnal circuit vary to some extent
according to adjustments, use them as reference values.

5.NOTE FOR REPAIRING SERVICE
This mode l's p ower circu it is p artly diff erent 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 point s.
(1)Do not touch the LIVE side GND or the LIVE side GN D an d 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 circuit and
circ ui t constant s may be subject to c hange for impro vem ent
without any notice.
NOTE
Due improvement in performance, some part numbers show
in the circuit diagram may not agree with those i ndicate d in
the part list.
When ordering parts, please use the numbers that appear
in th e Parts List .
