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 30kV 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. 4. 5. 6. 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 1,4Vrms. 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 30kV without causing X-Radiation.

3.
NOTE: It is important to use an accurate periodically calibrated high voltage meter. 1. Set the brightness to minimum. 2. Measure the high voltage. The meter should indicate. 29kV ± 1kV. If the meter indication is out of tolerance, immediate service and correction is required to prevent the possibility of premature component failure. 3. To prevent any X-Radiation possibility, it is essential to use the specified tube.

ALIGNMENT PROCEDURE AND OPTION SETTING
Self Check Mode To enter self check mode, set the programme position to Channel 99. Set sharpness to a minimum, press the status button ( + ) on the remote contol whilst simultaneously pressing the down button ( ) at the front of the set. This should bring the set into self check mode. Entering SERVICE mode Whilst in self check mode, press the mute remote key ( ) and local down button on the set ( ) simultaneously. The user must make sure that Sharpness is set to a minimum and that the programme position is set to Channel 99 as well. This should bring the user to service mode1. Scroll through the service items using the cursor up and down keys and adjust accordingly using the -/+ keys on the remote. Service mode navigation Up /Down remote keys -/+ remote keys TV/AV :scroll through the service items available. :Decrement/Increment the values within range. :Store the current data.

Cut Off UG2 alignment:
Adjust it on AV mode. Set condition is in AV mode without signal. Place the set into an Ageing Test for more than 15 minutes. Adjust the unit to the following settings. R-Cut=32, G-Cut=32, R-Drv=42, G-Drv=42, B-Drv=42. Press the G2 button on the service remote. Adjust the Screen Volume on the FBT until the indicator on the set will be lit. Adjust this after performing CUT OFF UG2 alignment. Place the set into an ageing test for approximately 15 minutes. Generate a gray scale pattern from a Pattern Generator. Set the colour balance to normal position. Press the FACTORY button on the service remote. Adjust accordingly using +/- button on the service remote to whiten the settings of R-Cut, G-Cut, R-Drv and G-Drv at each section equally.B-Drv step number however should be fixed at 42.

IMPORTANT SAFETY NOTICE
Components identified by mark have special characteristics important for safety. When replacing any of these components, use only manufacturers' specified parts.
NOTE
1. RESISTOR All resistors are carbon ¼W 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 µF unless otherwise stated. COIL Unit of inductance is µH, unless otherwise stated. TEST POINT Test Point Position

This indicates the specific waveform that can be found at the given point on the schematic.
These schematic diagrams are the latest 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.
