11 Schematic Diagram11.1. Schematic Diagram NotesNotes :1. ResistorUnit of resistance is OHM [Ω] (K = 1 000, M = 1 000 000).2. CapacitorUnit of capacitance is μF unless otherwise noted.3. CoilUnit of inductance is μF unless otherwise noted.4. Test Point: Test Point position5. Earth Symbol: Chassis Earth (Cold) : Line Earth (Hot)6. Voltage MeasurementVoltage is measured using DC voltmeter.Conditions of the measurement are the following :Power Source....................AC AUTO 110-240 V, 50/60 HzReceiving Signal................Colour Bar signal (RF)All customer’s controls.......Maximum positions7. Number in red circle indicates waveform number.(See waveform pattern table)8. When an arrow mark ( ) is found, connection is easily found from the direction of the arrow.9. Indicates the major signal flow: Video Audio10. This schematic diagram is the latest at the time of printing and subject to change without notice.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 following 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.26TX-26LE8A
