STANDARD CIRCUIT DIAGRAM

NOTE ON USING CIRCUIT DIAGRAMS

1.SAFETY

The components identified by the symbol and shading arecritical 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

following conditions.

(1)Input signal : Colour bar signal

(2)Setting positions ofeach knob/button andvariable resistor

(3)Internal resistance of tester :DC 20k /V

(4)Oscilloscope sweeping time :H 20µs/div

:V 5ms/div

:Others Sweeping time isspecified

(5)Voltage values :All DC voltage values

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

3.INDICATION OF PARTS SYMBOL [EXAMPLE]

In the PW board :R1209 R209

4.INDICATIONS ON THE CIRCUIT DIAGRAM(1)Resistors

5.NOTE FOR REPAIRING SERVICE

This model's power circuit is partly different in the GND. Thedifference of the GND is shown by the LIVE : ( ) side GND and theISOLATED(NEUTRAL) : ( ) side GND.Therefore, care must betaken for the following points.

(1)Do not touch the LIVE side GND or the LIVE side GND and theISOLATED(NEUTRAL) side GND simultaneously. If the abovecaution is not respected, an electric shock may be caused.Therefore, make sure that the power cord is surely removed fromthe 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 measurewith a measuring apparatus ( oscilloscope, etc.) the LIVE side GNDand 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 andcircuit constants may be subject to change for improvementwithout any notice.

NOTE

Due improvement in performance, some part numbers showin the circuit diagram may not agree with those indicated inthe part list.When ordering parts, please use the numbers that appearin the Parts List.
