SCHEMATIC DIAGRAM FOR MODELS
TX-29/25AD1E
(EURO-2S CHASSIS)
Notes
1.
RESISTOR
All resistors are carbon ¼W resistor, unless marked.
Unit of resistance is OHM (W) (K=1,000, M=1,000,000).
2.
CAPACITOR
All capacitors are ceramic 50V capacitors, unless marked, the unit of capacitance is mF unless otherwise stated.
3.
COIL
Unit of inductance is mH, unless otherwise stated.
4.
TEST POINT
:Test Point Position
:Waveform Test Point Position

EARTH SYMBOL
Chassis Earth (Cold)
Line Earth (Hot)
6.
VOLTAGE MEASUREMENT
Voltage is measured by a DC voltmeter.
Measurement conditions are as follows:
Power source
AC 220-240V, 50Hz
Receiving Signal
Colour Bar signal (RF)
All customer controls
Maximum position
7.
: Indicates the Video signal path
: Indicates the Audio signal path
: Indicates the Vertical/Horizontal signal path
8.
This schematic diagram is the latest at the time of printing and is subject to change without notice.
Precautions
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.
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. All circuits, except the Power Circuit, are COLD.
