SAFETY PRECAUTIONSGENERAL GUIDE LINES

1. It is advisable to insert an isolation transformer in thea.c. supply before servicing a hot chassis.

2. When servicing, observe the original lead dress in thehigh voltage circuits. If a short circuit is found, replaceall parts that have been overheated or damaged bythe short circuit.

3. After servicing, see that all the protective devicessuch as insulation barriers, insulation papers, shieldsand isolation R-C combinations are correctlyinstalled.

4. When the receiver is not being used for a long periodof time, unplug the power cord from the a.c. outlet.

5. Potentials as high as 27.5kV are present when thisreceiver is in operation. Operation of the receiverwithout the rear cover involves the danger of a shockhazard from the receiver power supply. Servicingshould not be attempted by anyone who is notfamiliar with the precautions necessary when workingon high voltage equipment. Always discharge theanode of the tube.

6. After servicing make the following leakage currentchecks to prevent the customer from being exposedto shock hazard.

LEAKAGE CURRENT COLD CHECK1. Unplug the a.c. cord and connect a jumper between

the two prongs of the plug.2. Turn on the receiver’s power switch.3. Measure the resistance value with an ohmmeter,

between the jumpered a.c. plug and each exposedmetallic cabinet part on the receiver, such as screwheads, aerials, connectors, control shafts etc. Whenthe exposed metallic part has a return path to thechassis, the reading should be between 4M ohm and20M ohm. When the exposed metal does not have areturn path to the chassis, the reading must beinfinite.

LEAKAGE CURRENT HOT CHECK1. Plug the a.c. cord directly into the a.c. outlet. Do not

use an isolation transformer for this check.2. Connect a 2kΩ 10W resistor in series with an

exposed metallic part on the receiver and an earth,such as a water pipe.

3. Use an a.c. voltmeter with high impedance tomeasure the potential across the resistor.

4. Check each exposed metallic part and check thevoltage at each point.

5. Reverse the a.c. plug at the outlet and repeat each ofthe above measurements.

6. The potential at any point should not exceed1.4V rms. In case a measurement is outside the limitsspecified, there is a possibility of a shock hazard, and

the receiver should be repaired and rechecked beforeit is returned to the customer.

X-RADIATION WARNING1. The potential sources of X-Radiation in TV sets are

the high voltage section and the picture tube.2. When using a picture tube test jig for service, ensure

that the jig is capable of handling 27.5kV withoutcausing X-Radiation.

NOTE: It is important to use an accurate periodicallycalibrated high voltage meter.1. Set the brightness to minimum.2. Measure the high voltage. The meter should indicate

26.5kV ± 1kV.If the meter indication is out of tolerance, immediateservice and correction is required to prevent thepossibility of premature component failure.

3. To prevent any X-Radiation possibility, it is essentialto use the specified tube.

ALIGNMENT PROCEDURE AND OPTION SETTING

Entering SERVICE modeService mode is entered by selecting the “mute” remote key and local “down” simultaneously with the sharpness DAC set toMinimum and programme position 99 selected.Service mode 2 is selected by pressing the Recall remote key while in service mode 1.Service mode navigation- Up /Down remote keys :cycle through the service items available.- -/+ remote keys :Decrement/Increment the values within range.- TV/AV :Store the current data.- 0 – 7 digit keys :Toggle bits 0-7 in option byte (service mode 2).

Order Item Range

Sub-Colour: Set sub-colour to 16.

Sub-Brightness: Set sub-colour to 33.

G2 alignment: Before entering into service mode, recall the nominal picture setting :remote key “N”.From this setting, increase brightness by 11 steps and reduce sharpness to minimum.Tune a colour bar signal on Prg 99 and enter into SVC mode. In SVC mode , select “G2” item and press – or + remote key to control software disable vertical deflection. The user must then adjust G2 voltage on FBT, to find the point where LED is ON. Press – or + remote key to return to normal SVC mode.

White balance: - Select a dark picture and adjust Red Cut and Green Cut to the desired colour temperature.- Select a bright picture, set Blue Drive to 32 and adjust Red Drive, and Green Drive to the desired colour temperature.

NOTE1. RESISTOR

All resistors are carbon ¼W resistor, unless marked otherwise.Unit of resistance is OHM (Ω) (k=1,000, M=1,000,000)

2. CAPACITORSAll capacitors are ceramic 50V unless marked otherwise.Unit of capacitance is µF unless otherwise stated.

3. COILUnit of inductance is µH, unless otherwise stated.

4. TEST POINTTest Point Position

5. EARTH SYMBOL

Chassis Earth (Cold)

Line Earth (Hot)

6. VOLTAGE MEASUREMENTVoltage is measured by a d.c. voltmeter.Measurement conditions are as follows:Power source a.c. 220V-240V, 50HzReceiving 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.

REMARKSa. 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 causefuse 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.

NOTE1. 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, areCOLD.

IMPORTANT SAFETY NOTICEComponents identified by mark have special characteristicsimportant for safety. When replacing any of these components, useonly manufacturer's specified parts.
