Model No. : TH-50PF30U Schematic Diagram Note
Notes:
1. Resistor
Unit of resistance is OHM [Q] (K=1,000, M=1,000,000).
2. Capacitor
Unit of capacitance is ^F, unless otherwise noted.
3. Coil
Unit of inductance is H, unless otherwise noted.
4. Test Point
9 : Test Point position
5. Earth Symbol
h : Chassis Earth (Cold) ^ : Line Earth (Hot)
6. Voltage Measurement
Voltage is measured by a DC voltmeter.
Conditions of the measurement are the following:
Power Source .................................................... AC 120V, 60Hz
Receiving Signal
................................................ Colour Bar signal (RF)
All customer's controls ....................................... Maximum positions
7. When arrow mark (/) is found, connection is easily found from the direction of arrow.
8. Indicates the major signal flow. : Video ^ Audio ■=>
9. This schematic diagram is the latest at the time of printing and subject to change without
notice.
Notice: Use the parts number indicated on the Replacement parts List.
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.
