1. SAFETY

AV-21LS2 AV-21LX2 AV-2168TEE

STANDARD CIRCUIT DIAGRAM
Type
No indication MY MM PP MPP MF TF BP TAN (3) Coils No unit Others (4) Power Supply : B1 : B2(12V) : 9V : 5V : Ceramic capacitor : Mylar capacitor : Metalized mylar capacitor : Polypropylene capacitor : Metalized polypropylene capacitor : Metalized film capacitor : Thin film capacitor : Bipolar electrolytic capacitor : Tantalum capacitor : [H] : As specified

q NOTE ON USING CIRCUIT DIAGRAMS
The components identified by the symbol and shading are critical 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 : Color bar signal (2) Setting positions of each knob/button and variable resistor : Original setting position when shipped (3) Internal resistance of tester : DC 20k/V (4) Oscilloscope sweeping time : H 20S/div :V 5mS/div : Others Sweeping time is specified (5) Voltage values : All DC voltage values

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

9Respective voltage values are indicated
(5) Test point : Test point : Only test point display (6) Connecting method : Connector : Wrapping or soldering : Receptacle (7) Ground symbol : LIVE side ground : ISOLATED(NEUTRAL) side ground : EARTH ground : DIGITAL ground

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 : [M] 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

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 the LIVE side GND and ISOLATED(NEUTRAL) side GND at the same time with a measuring apparatus ( oscilloscope, etc.). If the above precaution is not respected , a fuse or any parts will be broken.

9Composition resistor 1/2 [W] is specified as 1/2S or Comp.
(2) Capacitors Capacitance value 1 or higher less than 1 Withstand voltage No indication AC indicated Others

: [pF] : [F] : DC50[V] : AC withstand voltage [V] : DC withstand voltage [V]

9 Electrolytic Capacitors
47/50[Example] : Capacitance value [F]/withstand voltage[V]

Since the circuit diagram is a standard one, the circuit and circuit constants may be subject to change for improvement without any notice.
