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 isolation 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 circuitry 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 position, 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 1MΩand 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 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.
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.

General Specification

1. Application Object
These instructions are applied to all of the color TV, CW62B.
2. Notes
(1) Because this is not a hot chassis, it is not necessary to use
an isolation transformer. However, the use of isolation
transformer will help protect test instrument.
(2) Adjustment must be done in the correct order.But the
adjustment can be changed by consideration of mass
production.
(3) The adjustment must be performed in the circumstance of
25±5°C of temperature and 65±10% of relative humidity if
there is no specific designation.
(4) The input AC voltage of the receiver must keep rating
voltage in adjusting.
(5) The receiver must be operated for about 20 minutes prior
to the adjustment.
(6) Signal: Received, the standard color signal.(65dB±1dB uV)
LG standard signal means the digital pattern
(PAL_EU 05CH,NTSC_US 13CH).
3. Focus adjustment
(1) Receive the Cross-Hatch Pattern(Fig 1).
(2) Set the picture condition on “DYNAMIC(CLEAR)” mode.
(3) Adjust the Focus volume of FBT,made the focus of the 1/4
part vertical line is best.
4. Purity & Convergence adjustment
Adjustment should be operated when using the CPT(without
ITC from CPT manufacturing place)
This adjustment must be done in the order of the following
flowchart.
4.1. Color purity adjustment
(1) It makes CPT or CABINET enough to demagnetization.
(2) Receive the signal of red raster.
(3) Unfasten DY and push DY to FUNNEL direction.
(4) Make R-Land be centered as cross Purity Magnet. That
time, 4 & 6 pole magnet should keep free gauss status.
(5) Make uniform RED Raster as moving DY,Check there is
purity problem or not on R/G/B,white Raster. Then fix screw
of DY.
(At this time, be careful about inclination and DY should be
fixed keeping horizontality.)
(6) Check the TV set in direction of EAST, WEST, SOUTH,
NORTH. Adjust with supporing MAGNET when adjustment
is not operated.
4.2. Convergence adjustment
These adjustments should be operaed at the best condition of
focus after finished purity adjustment.
(1) Receive the signal of cross hatch that BACK RASTER is
black.
(2) Adjust brightness so that there are 9 ~12 dots.

keep X,Y coordinate settle for the below list,adjust the
LOW LIGHT(4.5FL).
(3) From the initial data:BG(B-DRIVE) is 32,adjust RG(R-
