STANDARD CIRCUIT DIAGRAM
NOTE ON USING CIRCUIT DIAGRAMS
1. SAFETY
The components identified by the
are critical for safety. For continued safety replace safety
critical components only with the manufacturer’s
recommended parts.
symbol and shading
2. SPECIFIED VOLTAGE AND WAVEFORM VALUES
The voltage and waveform values have been measured under the
following conditions.
(1) Input signal : Colour bar signal
(2)
Setting positions of each knob/button and
variable resistor
(3) Internal resistance of tester : DC 20kΩ/V
(4) Oscilloscope sweeping time : H ⇒ 20µs/div
(5) Voltage values : All DC voltage values
: Original setting position when
shipped
:V ⇒ 5ms/div
: Others ⇒ Sweeping time is
specified
∗Since the voltage values of signal circuit vary to some extent
according to adjustments, use them as reference values.

5. NOTE FOR REPAIRING SERVICE
This model’s power circuit is partly different 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 observed, 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 the LIVE side GND and
ISOLATED(NEUTRAL) side GND at the same time with a measuring
apparatus ( oscilloscope, etc.). If the above precaution is not
observed, a fuse or any parts will be broken.
♦
Since the circuit diagram is a standard one, the circuit and
circuit constants may be subject to change for
improvement without any notice.
NOTE
♦
As a result of later performance improvement, some part
numbers shown in the circuit diagram may not agree with
those indicated in the part list.
When ordering parts, please use the numbers that appear
in the Parts List.
