Schematic Diagrams  
 
 
 
 
 
 
 
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.
