q 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 : Color 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 : Uninflammable 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]

: 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.
