1.  RESISTOR

All resistors are carbon ¼W resistor, unless marked otherwise.
Unit of resistance is OHM (

W) (k=1,000, M=1,000,000)

2.  CAPACITORS

All capacitors are ceramic 50V unless marked otherwise.
Unit of capacitance is 

mF unless otherwise stated.

3.  COIL

Unit of inductance is 

mH, 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

a.c. 220V-240V, 50Hz

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.

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.

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.

Components identified by

 mark have special characteristics

important for safety. When replacing any of these components, use
only manufacturers' specified parts.
