SAFETY PRECAUTIONS
GENERAL GUIDE LINES
1. 2. It is advisable to insert an isolation transformer in the a.c. supply before servicing a hot chassis. When servicing, observe the original lead dress in the high voltage circuits. If a short circuit is found, replace all parts that have been overheated or damaged by the short circuit. After servicing, see that all the protective devices such as insulation barriers, insulation papers, shields and isolation R-C combinations are correctly installed. When the receiver is not being used for a long period of time, unplug the power cord from the a.c. outlet. Potentials as high as 27.5kV are present when this receiver is in operation. Operation of the receiver without the rear cover involves the danger of a shock hazard from the receiver power supply. Servicing should not be attempted by anyone who is not familiar with the precautions necessary when working on high voltage equipment. Always discharge the anode of the tube. After servicing make the following leakage current checks to prevent the customer from being exposed to shock hazard. Unplug the a.c. cord and connect a jumper between the two prongs of the plug. Turn on the receiver's power switch. Measure the resistance value with an ohmmeter, between the jumpered a.c. plug and each exposed metallic cabinet part on the receiver, such as screw heads, aerials, connectors, control shafts etc. When the exposed metallic part has a return path to the chassis, the reading should be between 4M ohm and 20M ohm. When the exposed metal does not have a return path to the chassis, the reading must be infinite. Plug the a.c. cord directly into the a.c. outlet. Do not use an isolation transformer for this check. Connect a 2k 10W resistor in series with an exposed metallic part on the receiver and an earth, such as a water pipe. Use an a.c. voltmeter with high impedance to measure the potential across the resistor. Check each exposed metallic part and check the voltage at each point. Reverse the a.c. plug at the outlet and repeat each of the above measurements. The potential at any point should not exceed 1.4V rms. In case a measurement is outside the limits specified, there is a possibility of a shock hazard, and the receiver should be repaired and rechecked before it is returned to the customer.

X-RADIATION WARNING
1. 2. The potential sources of X-Radiation in TV sets are the high voltage section and the picture tube. When using a picture tube test jig for service, ensure that the jig is capable of handling 27.5kV without causing X-Radiation.

3.

NOTE: It is important to use an accurate periodically calibrated high voltage meter.

Set the brightness to minimum. Measure the high voltage. The meter should indicate 26.5kV ą 1kV. If the meter indication is out of tolerance, immediate service and correction is required to prevent the possibility of premature component failure. To prevent any X-Radiation possibility, it is essential to use the specified tube.

ALIGNMENT PROCEDURE AND OPTION SETTING
Entering SERVICE mode Service mode is entered by selecting the "mute" remote key and local "down" simultaneously with the sharpness DAC set to Minimum 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).

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. - 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.

IMPORTANT SAFETY NOTICE
Components identified by mark have special characteristics important for safety. When replacing any of these components, use only manufacturer's specified parts.

NOTE
1. RESISTOR All resistors are carbon źW resistor, unless marked otherwise. Unit of resistance is OHM () (k=1,000, M=1,000,000) CAPACITORS All capacitors are ceramic 50V unless marked otherwise. Unit of capacitance is ľF unless otherwise stated. COIL Unit of inductance is ľH, unless otherwise stated. TEST POINT Test Point Position

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.

REMARKS
a. b. c. d. Do not touch the hot part, or the hot and cold parts at the same time, as you are liable to a shock hazard. Do not short circuit the hot and cold circuits as electrical components may be damaged. 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. 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.
