STANDARD CIRCUI T 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 recommend e d parts.

2.SPECIFIED VOLTAGE AND WAVEFORM VALUES

The voltage and waveform values have been measured under the fo llowin g conditions.

(1)Input signal : Colour bar signal (2)Setting positions of

each knob/button and variable resistor

(3)Internal resistance of tester

:DC 20k

(4)Oscil los cope sweepi ng time

5mS/div

:Others

Sweeping time is specified

(5)Voltage values

:All DC voltage values

Sin ce th e vo l tage val ue s of si gn a l cir cuit va ry to s ome exte n t according to adjustments, use them as reference values.

4.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 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 sid e 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 standa rd one, the ci rcuit and circuit constants may be subject to change for i mpro vement without any notice.

NOTE Due improvement in performance, some part numbers show in the circuit diagram may not agree with those i ndi cate d in

the part list. When ordering part s, plea se us e the numbers that appear in the Parts List.
