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.

AC Volt-meter

When 25A is impressed between Earth and 2nd Ground for 1 second, Resistance must be less than 0.1

ADJUSTMENT INSTRUCTION

1. Application Range

This specification sheet is applied to all of the LCD TV with LD03R chassis.

2. Designation

(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. (3) The adjustment must be performed in the circumstance of

25 ºC ± 5 ºC of temperature and 65 % ± 10 % of relative humidity if there is no specific designation.

(4) The input voltage of the receiver must keep AC 100-240

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

In case of keeping module is in the circumstance of below 20 °C, it should be placed in the circumstance of above 15 °C for 3 hours.

[Caution] When still image is displayed for a period of 20 minutes or longer (especially where W/B scale is strong. Digital pattern 13ch and/or Cross hatch pattern 09ch), there can some afterimage in the black level area.

4.3. White Balance Adjustment

4.3.1 Overview

(1) W/B adj. Objective & How-it-works (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.

(4) Adj. condition : normal temperature

1) Surrounding Temperature : 25 ºC ± 5 ºC

2) Warm-up time: About 5 Min

3) Surrounding Humidity : 20 % ~ 80 %

4.3.2 Equipment

1) Color Analyzer: CA-210 (LED Module : CH 14)

2) Adj. Computer(During auto adj., RS-232C protocol is needed)

3) Adjust Remote control

4) Video Signal Generator MSPG-925F 720p/216-Gray (Model:217, Pattern:78)

-> Only when internal pattern is not available

A Color Analyzer Matrix should be calibrated using CS-1000

4.3.5. 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 -> 7. 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 7.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.
