NOTE ON USING CIRCUIT DIAGRAMS
/A
STANDARD CIRCUIT DIAGRAM
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
Type
•
No indication : Ceramic capacitor
MY : Mylar capacitor
MM : Metalized mylar capacitor
PP : Polypropylene capacitor
MPP : Metalized polypropylene capacitor
MF : Metalized film capacitor
TF : Thin film capacitor
BP : Bipolar electrolytic capacitor
TA N:Tantalum capacitor
(3) Coils
No unit : [µH]

Others : DC withstand voltage [V]
9 Electrolytic Capacitors
47/50[Example] : Capacitance value [µF]/withstand voltage[V]
(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 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.
Since the circuit diagram is a standard one, the circuit and cir-
•
cuit constants may be subject to change for improvement without any notice.
