5.NOTE FOR REPAIRING SERVICEThis model's power circuit is partly different in the GND. Thedifference of the GND is shown by the LIVE : ( ) side GND and theISOLATED(NEUTRAL) : ( ) side GND. Therefore, care must betaken for the following points.(1)Do not touch the LIVE side GND or the LIVE side GND and theISOLATED(NEUTRAL) side GND simultaneously. if the abovecaution is not respected, an electric shock may be caused.Therefore, make sure that the power cord is surely removed fromthe 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 measurewith a measuring apparatus ( oscilloscope, etc.) the LIVE side GNDand 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 andcircuit constants may be subject to change for improvementwithout any notice.NOTEDue improvement in performance, some part numbers showin the circuit diagram may not agree with those indicated inthe part list.When ordering parts, please use the numbers that appearin the Parts List.STANDARD CIRCUIT DIAGRAMNOTE ON USING CIRCUIT DIAGRAMS(7)Ground symbol: LIVE side ground: ISOLATED(NEUTRAL) side ground: EARTH ground: DIGITAL ground(6)Connecting method: Connector : Wrapping or soldering: Receptacle(5)Test point: Test point : Only test point displayRespective voltage values are indicated: B1: 9V : 5V: B2 (12V)(4)Power SupplyTypeMM : Metalized mylar capacitorPP : Polypropylene capacitorMPP : Metalized polypropylene capacitorMF : Metalized film capacitorTF : Thin film capacitorBP : Bipolar electrolytic capacitorTAN : Tantalum capacitor(3)CoilsNo unitOthers: [μH]: As specifiedNo indication : Ceramic capacitor(2)CapacitorsCapacitance value1 or higher : [pF]less than 1 : [μF]Withstand voltageNo indication : DC50[V]Others : DC withstand voltage [V]AC indicated : AC withstand voltage [V]Electrolytic Capacitors47/50[Example]: Capacitance value [μF]/withstand voltage[V]Composition resistor 1/2 [W] is specified as 1/2S or Comp.TypeNo indication : Carbon resistorOMR : Oxide metal film resistorMFR : Metal film resistorMPR : Metal plate resistorUNFR : Uninflammable resistorFR : Fusible resistor4.INDICATIONS ON THE CIRCUIT DIAGRAM(1)ResistorsResistance valueNo unit : [Ω]K : [kΩ]MRated allowable powerNo indication : 1/16 [W]Others : As specified: [MΩ]3.INDICATION OF PARTS SYMBOL [EXAMPLE]In the PW board : R1209 R2091.SAFETYThe components identified by the symbol and shading arecritical for safety. For continued safety replace safety ciriticalcomponents only with manufactures recommended parts.Since the voltage values of signal circuit vary to some extentaccording to adjustments, use them as reference values.2.SPECIFIED VOLTAGE AND WAVEFORM VALUESThe voltage and waveform values have been measured under thefollowing conditions.(1)Input signal : Colour bar signal(2)Setting positions ofeach knob/button andvariable resistor(3)Internal resistance of tester : DC 20kΩ/V(4)Oscilloscope sweeping time : H 20μs / div: V 5ms / div: Othters Sweeping time isspecified(5)Voltage values : All DC voltage values: Original setting positionwhen shippedDT-V100CG/E, DT-V100CG/U(No.YA322)2-1Preliminary
