1. It is advisable to insert an isolation transformer in the
a.c. supply before servicing a hot chassis.
2. 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.
3. After servicing, see that all the protective devices
such as insulation barriers, insulation papers, shields
and isolation R-C combinations are correctly
installed.
4. When the receiver is not being used for a long period
of time, unplug the power cord from the a.c. outlet.
5. Potentials as high as 33kV [31,5kV] 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.
6. After servicing make the following leakage current
checks to prevent the customer from being exposed
to shock hazard.
LEAKAGE CURRENT COLD CHECK
1. 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 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.
LEAKAGE CURRENT HOT CHECK
1. 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 to
measure the potential across the resistor.
4. Check each exposed metallic part and check the
voltage at each point.
5. Reverse the a.c. plug at the outlet and repeat each of
the previous measurements.
6. The potential at any point should not exceed
1,4 Vrms. 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. 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 33kV [31,5kV]
without causing X-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 should indicate:
32kV ± 1kV [30,5kV ± 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.
To adjust Cutoff connect an oscilloscope to the Blue cathode. Adjust
the screen VR until the black level is 170V +0V/-5V.

SELF CHECK
Self-check is used to automatically check the bus lines and hexadecimal code of the TV set.To enter Self-Check mode, press
the STATUS button on the remote control and at the same time press the down (-/v) button on the customer controls at
the front the TV set. To exit Self Check, switch off the TV set at the power button.
(The figures below are nominal and used for representative purposes only.)
1. Set the Bass to maximum position, set the Treble to minimum position, set the Volume to minimum then press the
down button (-/v) on the customer controls at the front of the TV and at the same time press the INDEX button on the
remote control, this will place the TV into the Service Mode 1.
2. Press the RED/GREEN buttons to step up / down through the functions.
3. Press the YELLOW/BLUE buttons to alter the function values.
4. Press the STR button after each adjustment has been made to store the required values.
5. To exit the Service Mode, press the "N" button.
