Notes:
1. Resistor
All resistors are cabon 1/4W resistor, unless marked as follows:
Unit of resistance is OHM[ ] (K=1,000, M=1,000,000).
: Nonflammable
: Metal Oxide
: Solid
: Metal Film
: Wire Wound
: Fuse
2. Capacitor
All capacitors are ceramic 50V capacitor, unless marked as follows:
Unit of capacitance is F, unless otherwise noted.
: Temperature Compensation
: Electrolytic
: Polyester
: Bipolar
: Metalized Polyester
: Dipped Tantalum
: Polypropylene
: Z-Type
3. Coil
Unit of inductance is F, unless otherwise noted.
4. Test Point
: Test Point position
5. Earth Symbol
: Chassis Earth (Cold)
: Line Earth (Hot)
6. Voltage Meaaurement
Voltage is measured by a DC voltmeter.
Conditions of the measurement are the following:
Power Source
AC 100-240V, 50/60Hz
Receiving Signal
Colour Bar signal(RF)
All customer’s controls
Maximum positions
7. Number in red circle indicates waveform nember.
(See wavefom pattern table.)
8. When arrow mark( ) is found, connection is easily found from the direction of arrow
9. Indicates the major signal flow.

Remarks:
1. The Power 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. Take
the follwing precautions.
All circuits, except the Power Circuit, are cold.
Precautions
a. Do not touch the hot part or the hot and cold parts at the same time or
you may be shocked.
b. Do not short-circuit the hot and cold circuits or a fuse may blow and
parts may break.
c. Do not connect an instrument, such as an oscilloscope, to the hot and
cold circuits simultaneously or a fuse may blow.
Connect the earth of instruments to the earth connection of the circuit
being measured.
d. Make sure to disconnect the power plug before removing the chassis.
2. Following diodes are interchangeable.
MA150-MA162(Replacement part)
Components identified by
mark have special characteristics important for safety.
When replacing any of these components, use only manufacture’s specified parts.
