1 Safety Precautions
1.1. General Guide
1. It is advisable to insert an isolation transformer in the AC supply before servicing a hot chassis.
2. When servicing, observe the original lead dress, especia lly the lead dress in the high voltage circuits. If a short circuit is found, replace all parts which have been overheated or damaged by the short circuit.
3. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers, shields and isolation R-C combinations, are properly installed.
4. When the receiver is not to be used for a long period of time, unplug the power cord from the AC outlet.
3. Measure the resistance value, with an ohmmeter, between the jumper AC 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
M
and 20 M

return path to the chassis, the reading must be infinite.

. When the exposed metal does not have a
1.3. Leakage Current Hot Check
(See Fig. 1)
1. Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this check.
2. Connect a 2kΩ, 10 W resistor in series with an exposed metallic part on the receiver and an earth such as a water pipe.
3. Use an AC voltmeter, with high impedance type, to measure the potential across the resistor.
4. Check each exposed metallic part, and measure the voltage at each point.

5. Potential, as high as 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 thoroughly familiar with the precautions necessary when working on high voltage equipment. Always discharge the anode of the picture tube to the receiver chassis before handling the tube.
6. After servicing make the following leakage current checks to prevent the customer from being exposed to shock hazards.
32.0
kV is present when this receiver
1.2. Leakage Current Cold Check
1. Unplug the AC cord and connect a jumper between the two prongs on the plug.
5. Reverse the AC plug in the AC outlet and repeat each of the above measurements.
6. The potential any point should not exceed case of a measurement being outside of 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.

1.4. X-Radiation
Warning:
1. The potential sources of X-Radiation in TV sets are the EHT section and the picture tube.
2. When using a picture tube test rig for service, ensure that the rig is capable of handling Radiation.
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 reading should indicate tolerance, immediate service and correction is required to prevent the possibility of premature component failure.
3. To prevent the possibility of X-Radiation, it is essential to use the specified picture tube.

2 SERVICE HINTS
2.1. HOW TO REMOVE THE REAR COVER
1. Remove the 9 screws as shown in Fig. 1.
Fig. 1
2.2. HOW TO MOVE THE CHASSIS INTO SERVICE POSITION
1. Hold and lift the rear of the chassis and gently pull the
chassis towards you as shown in Fig. 3.
2. Release the respective wiring clips and rotate the chassis
vertically through 90° anticlockwise.
3. After servicing replace the bead clamper and ensure all
wiring is returned to its original position before returning the receiver to the customer.
2.3. HOTEL MODE
Purpose
1. At Hotels, this Mode prevents the customer from changing the TV preset data such as Channel preset data.
