SCHEMATIC DIAGRAMS FLAT COLOUR TELEVISION AV-21C314/V CD-ROM No.SML200410 BASIC CHASSIS CW COPYRIGHT © 2004 Victor Company of Japan, Limited No.YA159 2004/9 AV-21C314/V 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 ciritical 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 of each knob/button and variable resistor : Original setting position when shipped (3)Internal resistance of tester : DC 20kΩ/V (4)Oscilloscope sweeping time :H 20µs / div :V 5ms / div : Othters (5)Voltage values Sweeping time is specified : All DC voltage values Since the voltage values of signal circuit vary to some extent according to adjustments, use them as reference values Type No indication MM PP MPP MF TF BP TAN : Ceramic capacitor : Metalized mylar capacitor : Polypropylene capacitor : Metalized polypropylene capacitor : Metalized film capacitor : Thin film capacitor : Bipolar electrolytic capacitor : Tantalum capacitor (3)Coils No unit : [µH] Others : As specified (4)Power Supply : B1 : B2 (12V) : 9V : 5V Respective voltage values are indicated (5)Test point : Test point : Only test point display (6)Connecting method : Connector : Wrapping or soldering 3.INDICATION OF PARTS SYMBOL [EXAMPLE] In the PW board : R209 4.INDICATIONS ON THE CIRCUIT DIAGRAM Resistance value K M : [Ω] : [kΩ] : [MΩ] Rated allowable power No indication : 1/16 [W] Others : As specified Type No indication : Carbon resistor OMR : Oxide metal film resistor MFR : Metal film resistor MPR : Metal plate resistor UNFR : Uninflammable resistor FR : Fusible resistor Composition resistor 1/2 [W] is specified as 1/2S or Comp (2)Capacitors Capacitance value or higher less than (7)Ground symbol : LIVE side ground : ISOLATED(NEUTRAL) side ground (1)Resistors No unit : Receptacle R209 : [pF] : [µF] Withstand voltage No indication : DC50[V] Others : DC withstand voltage [V] AC indicated : AC withstand voltage [V] Electrolytic Capacitors 47/50[Example]: Capacitance value [µF]/withstand voltage[V] : EARTH ground : DIGITAL ground 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 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 NOTE Due 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 (No.YA159)2-1 CONTENTS SEMICONDUCTOR
