SAFETY PRECAUTIONS
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 X-RADIATION, Shock, Fire, or other Hazards.
Do not modify the original design without permission of manufacturer.
General Guidance
An lsolation Transformer should always be used during
the servicing of a receiver whose chassis is not isolated from
the AC power line. Use a transformer of adequate power rating
as this protects the technician from accidents resulting in
personal injury from electrical shocks.
It will also protect the receiver and it's components from being
damaged by accidental shorts of the circuitary that may be
inadvertently introduced during the service operation.
If any fuse (or Fusible Resistor) in this TV receiver is blown,
replace it with the specified.
When replacing a high wattage resistor (Oxide Metal Film
Resistor, over 1W), keep the resistor 10mm away from PCB.
Keep wires away from high voltage or high temperature parts.
Due to high vacuum and large surface area of picture tube,
extreme care should be used in handling the Picture Tube.
Do not lift the Picture tube by it's Neck.
X-RAY Radiation
Warning:
To determine the presence of high voltage, use an accurate
high impedance HV meter.
Adjust brightness, color, contrast controls to minimum.
Measure the high voltage.
The meter reading should indicate
23.5 ¡1.5KV: 14-19 inch, 26 ¡1.5KV: 19-21 inch,
29.0 ¡1.5KV: 25-29 inch, 30.0 ¡1.5KV: 32 inch
If the meter indication is out of tolerance, immediate service
and correction is required to prevent the possibility of
premature component failure.
Before returning the receiver to the customer,
always perform an AC leakage current check on the exposed
metallic parts of the cabinet, such as antennas, terminals, etc.,
to be sure the set is safe to operate without damage of
electrical shock.
Leakage Current Cold Check(Antenna Cold Check)
With the instrument AC plug removed from AC source,
connect an electrical jumper across the two AC plug prongs.
Place the AC switch in the on positioin, connect one lead of
ohm-meter to the AC plug prongs tied together and touch other
ohm-meter lead in turn to each exposed metallic parts such as
antenna terminals, phone jacks, etc.
If the exposed metallic part has a return path to the chassis, the
measured resistance should be between 1MΩ and 5.2MΩ.
When the exposed metal has no return path to the chassis the
reading must be infinite.
An other abnormality exists that must be corrected before the
receiver is returned to the customer.
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 the AC cord into the AC outlet and repeat AC
voltage measurements for each esposed 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 sepcified, there is
possibility of shock hazard and the set must be checked and
repaired before it is returned to the customer.
Leakage Current Hot Check circuit
The source of X-RAY RADIATION in this TV receiver is the
High Voltage Section and the Picture Tube.
For continued X-RAY RADIATION protection, the
replacement tube must be the same type tube as specified in
the Replacement Parts List.

2) Press Channel UP/DOWN button for desirous function
Adjustment.
3) Press Volume UP/DOWN button to adjust the data.
4) Adjustment Sequence
a- Change the "CONTRAST", "BRIGHT" and adjust to be 3.5
Ft_L.
b- Adjust "Y" value of High Light with GD(G-Drive) and adjust
"X" value with BD(B-Drive) and make color coordinates
of High Light which is specified in "__clause".
c- Change the "CONTRAST", "BRIGHT" and adjust to be 4.5
Ft_L.
d- Adjust "Y" value of Low Light with GC(G-Cutoff) and
adjust "X" value with BC(B-Cutoff) and make color
coordinates of Low Light which is specified in "__clause".
e- Repeat the adjustment from 'a' to 'd' until the High, Low
color coordinates of "_clause" is satisfied.
f- Check the adjusted color coordinates with white balance
meter.
8. Deflection Data Adjustment
8-1. Preparation for Adjustment
1) Deflection Data Adjustment should be performed with the
remote controller for handset.
2) Enter the Adjustment mode by pressing the INSTART button.
3) Select the DEFLECT to deflection Data Adjustment.
4) Press the Channel UP/DOWN button to select adjustment
items.
5) Press the Volume UP/DOWN button to adjust the data.
6) The TV set receives PAL-B/G Digital pattern.
NOTE : If production line doesnÕt the production line of LG
TV,receive available deflection adjustment pattern.
VL (Vertical Linearity)
Adjust so that the boundary line between upper and lower half is in
accord with geometric horizontal center of the CPT.
VA (Vertical Amplitude)
