No. 52075 Nov. 2002 AV-21W33 AV-21W33B AV-21W33/T AV-21W33B/T STANDARD CIRCUIT DIAGRAM q NOTE ON USING CIRCUIT DIAGRAMS • Type : Ceramic capacitor : Mylar capacitor 1. SAFETY No indication : Metalized mylar capacitor MY : Polypropylene capacitor The components identified by the symbol and shading are MM : Metalized polypropylene capacitor critical for safety. For continued safety replace safety critical PP : Metalized film capacitor components only with manufactures recommended parts. MPP : Thin film capacitor MF : Bipolar electrolytic capacitor 2. SPECIFIED VOLTAGE AND WAVEFORM VALUES TF : Tantalum capacitor BP The voltage and waveform values have been measured under the TAN following conditions. (1) Input signal : Color bar signal (2) Setting positions of each knob/button and variable resistor (3) Coils No unit : Original setting position when Others : [µH] : As specified shipped (3) Internal resistance of tester : DC 20kØ/V (4) Oscilloscope sweeping time : H ⇒ 20µS/div (4) Power Supply :V ⇒ 5mS/div : B1 : B2(12V) : Others ⇒ Sweeping time is : 9V specified. (5) Voltage values : All DC voltage values : 5V 9Since the voltage values of signal circuit vary to some extent ac- 9Respective voltage values are indicated cording to adjustments, use them as reference values. (5) Test point 3. INDICATION OF PARTS SYMBOL [EXAMPLE] : Test point • In the PW board : R1209 → R209 : Only test point display 4. INDICATIONS ON THE CIRCUIT DIAGRAM (6) Connecting method : Connector (1) Resistors : Wrapping or soldering • Resistance value : Receptacle No unit : [Ø] (7) Ground symbol k : [kØ] : LIVE side ground : ISOLATED(NEUTRAL) side ground M : [MØ] : EARTH ground : DIGITAL ground • Rated allowable power 5. NOTE FOR REPAIRING SERVICE No indication : 1/16 [W] This model’s power circuit is partly different in the GND. The difference Others : As specified of the GND is shown by the LIVE : ( ) side GND and the : Carbon resistor ISOLATED(NEUTRAL) : ( ) side GND. Therefore, care must be taken • Type for the following points. (1) Do not touch the LIVE side GND or the LIVE side GND and the No indication ISOLATED(NEUTRAL) side GND simultaneously. If the above cau- OMR : Oxide metal film resistor tion is not respected, an electric shock may be caused. Therefore, make sure that the power cord is surely removed from the recepta- MFR : Metal film resistor cle when, for example, the chassis is pulled out. (2) Do not short between the LIVE side GND and ISOLATED(NEUTRAL) MPR : Metal plate resistor side GND or never measure the LIVE side GND and ISOLATED(NEUTRAL) side GND at the same time with a measur- UNFR : Non-Flammable resistor ing apparatus ( oscilloscope, etc.). If the above precaution is not respected , a fuse or any parts will be broken. FR : Fusible resistor 9Composition resistor 1/2 [W] is specified as 1/2S or Comp. (2) Capacitors • Capacitance value 1 or higher : [pF] less than 1 : [µF] • Withstand voltage No indication : DC50[V] AC indicated : AC withstand voltage [V] Others : DC withstand voltage [V] 9 Electrolytic Capacitors 47/50[Example] : Capacitance value [µF]/withstand voltage[V] • Since the circuit diagram is a standard one, the circuit and cir- cuit constants may be subject to change for improvement with- out any notice.
