STANDARD CIRCUIT DIAGRAMNOTE ON USING CIRCUIT DIAGRAMS
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 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 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.
(7)Ground symbol

4.INDICATIONS ON THE CIRCUIT DIAGRAM(1)Resistors
Resistance value
No unit : [Ω]
K : [kΩ]M
Rated allowable powerNo indication : 1/16 [W]
Others : As specified
: [MΩ]
3.INDICATION OF PARTS SYMBOL [EXAMPLE]
In the PW board : R209 R209
1.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 of each knob/button and variable 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 position when shipped
