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 Exploded View.
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.

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 1 W), keep the resistor 10 mm away from PCB.

Keep wires away from high voltage or high temperature parts.

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 1 MΩ and 5.2 MΩ.
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 1.5 K / 10 watt resistor in parallel with a 0.15 uF 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

0.5 mA.
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.

V~, 50 / 60Hz.
(5) The receiver must be operated for about 5 minutes prior to

the adjustment when module is in the circumstance of over

15.

In case of keeping module is in the circumstance of 0 °C, it
should be placed in the circumstance of above 15 °C for 2
hours

(2) Objective: To reduce each Panel’s W/B deviation
(3) How-it-works : When R/G/B gain in the OSD is at 192, it

means the panel is at its Full Dynamic Range. In order to
prevent saturation of Full Dynamic range and data, one of
R/G/B is fixed at 192, and the other two is lowered to find
the desired value.

A Adj. Map

A 3 Command White Balance Adj. Map

A Infrared Sensor Adj. Map

4.2.5. Adj. method

(1) Auto adj. method

1) Set TV in adj. mode using POWER ON key.

2) Zero calibrate probe then place it on the center of the
Display.

3) Connect Cable (RS-232C)

4) Select mode in adj. Program and begin adjustment.

5) When adj. is complete (OK Sing), check adj. status pre
mode. (Warm, Medium, Cool)

6) Remove probe and RS-232C cable to complete adj.

A W/B Adj. must begin as start command “wb 00 00” , and

finish as end command “wb 00 ff”, and Adj. offset if need.

(2) Manual adj. method

1) Set TV in Adj. mode using POWER ON

2) Zero Calibrate the probe of Color Analyzer, then place it
on the center of LCD module within 10cm of the surface.

3) Press ADJ key -> EZ adjust using adj. R/C -> 9.White­Balance then press the cursor to the right (KEY

G).

(When KEY(G) is pressed 216 Gray internal pattern will
be displayed)

4) One of R Gain / G Gain / B Gain should be fixed at 192,
and the rest will be lowered to meet the desired value.

5) Adj. is performed in COOL, MEDIUM, WARM 3 modes
of color temperature.

A If internal pattern is not available, use RF input. In EZ

Adj. menu 9.White Balance, you can select one of 2 Test

-pattern: ON, OFF. Default is inner(ON). By selecting
OFF, you can adjust using RF signal in 216 gray pattern.

A Adj. condition and cautionary items

1) Lighting condition in surrounding area
Surrounding lighting should be lower 10 lux. Try to
isolate adj. area into dark surrounding.

2) Probe location
: Color Analyzer (CA-210) probe should be within
10cm and perpendicular of the module surface (80°~
100°)

3) Aging time

- After Aging Start, Keep the Power ON status during

5 Minutes.

- In case of LCD, Back-light on should be checked

using no signal or Full-white pattern.

4.2.6. Reference (White Balance Adj. coordinate

4.2.7. Edge LED White balance table

A IOP & Edge LED module change color coordinate because

of aging time.

A apply under the color coordinate table, for compensated

aging time.

- EDGE LED(LV3700)

4.3. EYE-Q function check

Step 1) Turn on TV
Step 2) Press EYE key of Adj. R/C
Step 3) Cover the Eye Q II sensor on the front of the using

your hand and wait for 6 seconds

Step 4) Confirm that R/G/B value is lower than 10 of the “Raw

Data (Sensor data, Back light)”. If after 6 seconds,
R/G/B value is not lower than 10, replace Eye Q II
sensor.

Step 5) Remove your hand from the Eye Q II sensor and wait

for 6 seconds.

Step 6) Confirm that “ok” pop up. If change is not seen,

replace Eye Q II sensor.

4.4. Option selection per country

(1) Overview

- Option selection is only done for models in Non-EU.

- Applied model: LD12B Chassis applied EU model.

(2) Method

1) Press ADJ key on the Adj. Remote Control, then select
Country Group Menu.

2) Depending on destination, select Country Group Code
04 or Country Group EU then on the lower Country
option, select US, CA, MX. Selection is done using +, ­or

GF KEY.

5. Tool Option selection

- Method : Press Adj. key on the Adj. Remote Control, then
select Tool option.

6. Ship-out mode check(In-stop)

After final inspection, press IN-STOP key of the Adj. R/C and
check that the unit goes to Stand-by mode.

7. GND and Internal Pressure check

7.1. Method

1) GND & Internal Pressure auto-check preparation

- Check that Power Cord is fully inserted to the SET.
(If loose, re-insert)

2) Perform GND & Internal Pressure auto-check

- Unit fully inserted Power cord, Antenna cable and A/V
arrive to the auto-check process.

- Connect D-terminal to AV JACK TESTER

- Auto CONTROLLER(GWS103-4) ON

- Perform GND TEST

- If NG, Buzzer will sound to inform the operator.

- If OK, changeover to I/P check automatically.
(Remove CORD, A/V form AV JACK BOX)

- Perform I/P test

- If NG, Buzzer will sound to inform the operator.

- If OK, Good lamp will lit up and the stopper will allow the
pallet to move on to next process.

7.2. Checkpoint

• TEST voltage

- GND: 1.5 KV/min at 100 mA

- SIGNAL: 3 KV/min at 100 mA

• TEST time: 1 second

• TEST POINT

- GND TEST = POWER CORD GND & SIGNAL CABLE
METAL GND

- Internal Pressure TEST = POWER CORD GND & LIVE &
NEUTRAL

• LEAKAGE CURRENT: At 0.5 mArms

8. USB S/W download(option, Service only)

1) Put the USB Stick to the USB socket

2) Automatically detecting update file in USB Stick

- If your downloaded program version in USB Stick is Low,
it didn’t work. But your downloaded version is High, USB
data is automatically detecting

3) Show the message “Copying files from memory”

4) Updating is starting.

5) Updating Completed, The TV will restart automatically

6) If your TV is turned on, check your updated version and
Tool option. (explain the Tool option, next stage)

* If downloading version is more high than your TV have,

TV can lost all channel data. In this case, you have to
channel recover. if all channel data is cleared, you didn’t
have a DTV/ATV test on production line.

* After downloading, have to adjust TOOL OPTION again.

1) Push "IN-START" key in service remote control.

2) Select "Tool Option 1" and Push “OK” button.

3) Push in the number. (Each model has their number.)
