STANDARD CIRCUIT DIAGRAM

NOTE ON USING CIRCUIT DIAGRAMS1.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 VALUESThe 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 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.

3.INDICATION OF PARTS SYMBOL [EXAMPLE]

In the PW board :R1209 R209

4.INDICATIONS ON THE CIRCUIT DIAGRAM(1)Resistors

Resistance value

No unit :[ ]

K :[K ]M

Rated allowable powerNo indication :1/ 16 [W]

Others :As specified

Type

No indication :Carbon resistorOMR :Oxide metal film resistorMFR :Metal film resistorMPR :Metal plate resistorUNFR :Uninflammable resistorFR :Fusible resistor

Composition resistor 1/2 [W] is specified as 1/2S or Comp.

(2)Capacitors

: Original setting position when shipped

5.NOTE FOR REPAIRING SERVICEThis 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 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 circuit constants may be subject to change for improvement without any notice.

NOTEDue improvement in performance, some part numbers show 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.

Type

MM :Metalized mylar capacitorPP :Polypropylene capacitorMPP :Metalized polypropylene capacitorMF :Metalized film capacitorTF :Thin film capacitorBP :Bipolar electrolytic capacitorTAN :Tantalum capacitor
