NOTE ON USING CIRCUIT DIAGRAMS

1. SAFETY

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 : Colour bar signal

(2)

Setting positions of each knob/button and variable resistor

:Original setting position when

shipped

(3) Internal resistance of tester : DC 20kØ/V

(4) Oscilloscope sweeping time : H ⇒20µS/div

:V ⇒5mS/div

:Others ⇒Sweeping time is

specified.

(5) Voltage values : All DC voltage values

9Since the voltage values of signal circuit vary to some extent ac-

cording to adjustments, use them as reference values.

3. INDICATION OF PARTS SYMBOL [EXAMPLE]

•In the PW board : R1209 → R209

4. INDICATIONS ON THE CIRCUIT DIAGRAM

(1) Resistors

•Resistance value

No unit : [Ø]

k:[kØ]

M:[MØ]

•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 : Non-Flammable resistor

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]

•Type

Others : As specified

(4) Power Supply

:B1

:B2(12V)

:9V

:5V

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

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 cau-

tion is not respected, an electric shock may be caused. Therefore,

make sure that the power cord is surely removed from the recepta-

cle 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 measur-

ing apparatus ( oscilloscope, etc.). 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 cir-

cuit constants may be subject to change for improvement with-

out any notice.
