Schematic Diagrams Note
NOTE
1. RESISTOR
All resistors are carbon ¼W resistor, unless marked otherwise.
Unit of resistance is OHM (
) (k=1,000, M=1,000,000)
2. CAPACITORS
All capacitors are ceramic 50V unless marked otherwise.
Unit of capacitance is
F unless otherwise stated.
3. COIL
Unit of inductance is
H, unless otherwise stated.
4. TEST POINT
Test Point Position
5. EARTH SYMBOL
Chassis Earth (Cold)
Line Earth (Hot)
6. VOLTAGE MEASUREMENT
Voltage is measured by a D.C. voltmeter.
Measurement conditions are as follows:
Power source 220V-240V AC, 50/60 Hz
Receiving Signal Colour Bar signal (RF)
All customer controls Maximum position
7.
Indicates the Video signal path
Indicates the Audio signal path
These schematic diagrams are the latest at time of printing and are subject to change without notice.
REMARKS
a. Do not touch the hot part, or the hot and cold parts at the same time, as you are liable to a shock hazard.
b. Do not short circuit the hot and cold circuits as electrical components may be damaged.
c. Do not connect an instrument, such as an oscilloscope, to the hot and cold circuits simultaneously as this may cause
fuse failure. Connect the earth of the instruments to the earth connection of the circuit being measured.
d. Make sure to disconnect the power plug before removing the chassis.
NOTE
1. The Power Supply Circuit contains a circuit area, which uses a separate power supply to isolate the earth connection.
The circuit is defined by HOT and COLD indications in the schematic diagram. All circuits, except the Power Circuit, are
COLD.
IMPORTANT SAFETY NOTICE
Components identified by mark have special characteristics
important for safety. When replacing any of these components, use
only manufacturers' specified parts.
