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 checkon 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 Mand 5.2 M.

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.

6. Final Assembly Adjustment6.1. White Balance Adjustment

6.1.1. Overview6.1.1.1. W/B adj. Objective & How-it-works

(1) Objective: To reduce each Panels W/B deviation

(2) How-it-works: When R/G/B gain in the OSD is at 192, itmeans 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.

(3) Adj. condition: normal temperature

- Surrounding Temperature: 255 C

- Warm-up time: About 5 Min

- Surrounding Humidity: 20% ~ 80%

Before White balance adjustment, Keep power on status,

dont power off

6.1.1.2. 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.

6.1.2. Equipment(1) Color Analyzer: CA-210 (NCG: CH 9 / WCG: CH12 / LED:

6.1.5. Adjustment method6.1.5.1 Auto adj. method

(1) Set TV in adj. mode using POWER ONLY (P-ONLY) 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 adj.(5) When adj. is completed (OK Sing), check adj. status of pre

mode (Cool, Medium, Warm)

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

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

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

6.1.5.2. 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 -> 6. White-

Balance then press the cursor to the right (KEY).

(When KEY() is pressed 204 Gray(80IRE) 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.

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

menu 6.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 204 Gray pattern.

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.

- If Test is failed, Buzzer operates.

- If Test is passed, execute next process (Hi-pot test).

(Remove A/V CORD from A/V JACK BOX)

(5) HI-POT test (Auto)

- If Test is failed, Buzzer operates.

- If Test is passed, GOOD Lamp on and move to next process

automatically.

9. USB S/W Download

(optional, 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 lower

than that of TV set, it didnt work. Otherwise USB data is

automatically detected.

(3) Show the message Copying files from memory

(5) Updating Completed, The TV will restart automatically

(6) If your TV is turned on, check your updated version and

Tool option.

* 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 didnt have a DTV/

ATV test on production line.
