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, especially 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

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.
5. Potential, as high as 32.0 kV is 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 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.
1.2. Leakage Current Cold Check
1. Unplug the AC cord and connect a jumper between the two prongs on
the plug.
2. Turn on the receiver’s power switch.
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
4

exposed metallic part has a return path to the chassis, the reading
should be between 4 M and 20 M . When the exposed metal does
not have a return path to the chassis, the reading must be infinite.
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 2k , 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. Reverse the AC plug in the AC outlet and repeat each of the above
measurements.
6. The potential any point should not exceed 1.0 V rms. In the 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 32.0 kV without causing X-Radiation. /
5

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 31.0 ± 1
kV. 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 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.
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. / / Note: This Mode is useful
for Hotels. You should not get into “Hotel mode” with Normal use.
Operation
1. To get into “Hotel Mode”, press the remote control “Recall” button and
Channel up “[+/ ]” key on the TV set simultaneously, after setting
the “Off-Timer” mode.
2. In this mode, the Channel up and down Function will be enabled as
normal and the maximum volume level for this mode is set at the
current volume level, i.e. the setting at the level before entering the
mode. However, other functions will be disabled.
3. To exit this mode, exit “Off-Timer” mode and the “Volume Down [-/
]” key simultaneously. / * This information is informed by Service
Manual only.
3. SELF CHECK
1. Self-Check is used to automatically check the bus lines and
7

hexadecimal code of the TV set.
2. To get into the Self-Check mode, press the down n [-/ ] button on
the customer controls at the front of the set, at the same time pressing
the HELP button on the remote control and the screen will show:
4. SERVICE MODE FUNCTION
MPU controls the functions switching for each IIC through IIC bus in this chassis. The following setting
and adjustment can be adjusted by remote control in Service Mode.
4.1. HOW TO ENTER SERVICE 1
1. In sound menu, set BASS to MAX and set TREBLE to MINIMUM.
2. Simultaneously press INDEX button on remote control and VOLUME
DOWN button [-] on the TV set.
4.2. HOW TO ENTER SERVICE 2
1. Set the channel to CH99.
2. Press HOLD button on remote control. / Note: / To exit Service mode,
press N or Power button on remote control.
