Many electrical and mechanical parts in this chassis have special safety-related
characteristics.
These parts are identified by in the Schematic Diagram and Replacement Parts List.
It is essential that these special safety parts should be replaced with the same components
as recommended in this manual to prevent Shock, Fire, or other Hazards.
Do not modify the original design without permission of manufacturer.
Leakage Current Hot Check (See below Figure)
Plug the AC cord directly into the AC outlet.
Do not use a line Isolation Transformer during this check.
Connect 1.5K/10watt resistor in parallel with a 0.15uF capacitor between a known good
earth ground (Water Pipe, Conduit, etc.) and the exposed metallic parts.
Measure the AC voltage across the resistor using AC voltmeter with 1000 ohms/volt or
more sensitivity.
Reverse plug of the AC cord into the AC outlet and repeat AC voltage measurements for
each exposed metallic part. Any voltage measured must not exceed 0.75 volt RMS, which
is, corresponds to 0.5mA.
In case any measurement is out of the limits specified, there is possibility of shock hazard
and the set must be checked and repaired before it is returned to the customer.

SERVICING PRECAUTIONS
CAUTION!!
Before servicing receivers covered by this service manual, read and follow the SAFETY
PRECAUTIONS on page 3 of this publication.
General Servicing Precautions
1.Always unplug the receiver AC power cord from AC power source before;
ⓐRemoving or reinstalling any component, circuit board module or any other receiver
assembly.
ⓑDisconnecting or reconnecting any receiver electrical plug or other electrical connection.
ⓒConnecting a test substitute in parallel with an electrolytic capacitor in the receiver.
CAUTION!! A wrong part substitution or incorrect polarity installation of electrolytic
capacitors may result in an explosion harzard.
2.Do not spray chemicals on or near this receiver or any of its assemblies.
3.Do not defect any plug/socket voltage interlocks with which receivers covered by this
service manual might be equipped.
4.Always connect the test receiver ground lead to the receiver chassis ground before
connecting the test receiver positive lead. Always remove the test receiver ground lead last.
5.Do not connect the test fixture ground strap to power supply heatsink in this receiver
Electrostatically Sensitive(ES) Devices
Some semiconductor(solid state) devices can be damaged easily by static electricity. Such
components commonly are called Electrostatically Sensitive(ES) Device.Examples
Circuit Board Foil Repair
Excessive heat applied to the copper foil of any printed circuit board will weaken the
adhesive that bonds the foil to the circuit board causing the foil th separate from or “lift-off”
the board.
The following guidelines and procedures should be flollowed whenever this condition is
encountered.
At IC Connections
To repair a defective copper pattern at IC connections use the following procedure to install
a jumper wire on the copper pattern side of the circuit board.(Use this technique only on IC
connections.)
1.Carefully remove the damaged copper pattern with a sharp knife.(Remove only as much
copper as absolutely necessary.)
2.Carefully scratch away the solder resist and acrylic coating(if used) from the end of the
remaining coopper pattern.
3.Bend a small “U” in one end of a small guage jumper wire and carefully crimp it around
the IC pin.
4.Route the jumper wire along the path of the out-away copper pattern and let it overlap
the previously scraped end of the good copper pattern. Solder the overlapped area and
clip off any excess jumper wire.

ADJUSTMENT
1. Safety Precautions
1. Never disconnect leads while the TV receiver is on.
2. Don't short any portion of circuits while power is on.
3. The adjustment must be done by the correct appliances. But this is changeable in
view of productivity.
4. Unless otherwise noted, set the line voltage to 230Vac 10%, 50Hz ./ 110Vac, 60Hz
2. Test Equipment required
1. RF signal generator (with pattern generator)
2. Multi meter (volt meter)
3. Oscilloscope
4. LCD Color analyzer
3. RF AGC (Automatic Gain Control) Adjustment
Note!! Adjust a RF AGC of world standard tuner only.
2 in 1 tuner need not AGC adjust.
The RF AGC was aligned at the time of manufacture for optimum performance over a wide
range conditions. Readjustment of RF AGC should not be necessary unless unusual local
conditions exist, such as ;
1) Channel interference in a CATV system.
2) Picture bending and/or color beats, which are unusually due to excessive RF signal
input when the receiver is too close to a transmitting tower or when the receiver is
connected to an antenna distribution system where the RF signal has been
amplified. In this case, the input signal should be attenuated (with pad or filter) to a
satisfactory level.
3) Picture noise caused by "broadcast noise" or weak signal. If the broadcast is
"clean" and the RF signal is at least 1mV (60dBu), the picture will be noise free in
any area.
Adjusting RF AGC to one end of rotation will usually cause a relatively poor signal to noise
ratio; Adjusting to the other end of rotation will usually cause a degradation of over load
capabilities resulting in color beats or adjacent channel interference.
Adjustment Note!!
1. Connect RF signal (65dB± 0.5dB) and turn on the TV.
2. Press MENU buttons on TV set and Remote Controller at the same time to get into
SVC mode.
3. Press YELLOW button on the Remote Controller several times to find AGC.
4. Press Volume UP/DOWN button until the AGC Voltage is the same as the Table
below.
5. Press OK button to memorize the data.
6. Press TV/AV button to exit SVC mode.
