SAFETY PRECAUTIONS

IMPORTANT SAFETY NOTICE

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
damage d by accidental sho rt s of the circuitr y th at 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 par t. 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.

2. Specification

(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 ±5 °C of temperature and 65±10% of relative humidity if

there is no specific designation.
(4) The input voltage of the receiver must keep 100~240V,

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 °C
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.

5. Final Assembly Adjustment

5.1. White Balance Adjustment

5.1.1. Overview

5.1.1.1. W/B adj. Objective & How-it-works
(1) Objective: To reduce each Panel’s W/B deviation
(2) 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.

(3) Adj. condition: normal temperature

- Surrounding Temperature: 25±5 °C

- Warm-up time: About 5 Min

- Surrounding Humidity: 20% ~ 80%

- Before White balance adjustment, Keep power on status,
don’t power off

5.1.1.2. 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 Pow er ON status during 5

Minutes.

- In case of LCD, Back-light on should be checked using no

signal or Full-white pattern.

5.1.2. Equipment

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

5.1.5. Adjustment method

5.1.5.1 Auto WB calibration
(1) Set TV in ADJ mode using P-ONLY key (or POWER ON

key)

(2) Place optical probe on the center of the display

- It need to check probe condition of zero calibration before
adjustment.

(3) Connect RS-232C Cable
(4) Select mode in ADJ Program and begin a adjustment.
(5) When WB adjustment is completed with OK message,

check adjustment status of pre-set mode (Cool, Medium,
Warm)

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

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

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

Check inpu t signal format.
Is it supported?

Y

Check AC cable for damage
For damage or open condu ctor

Y

Check JK3800
Can you see the normal waveform?

Y

Check th e input of MTK(IC105).
Measure waveform at C345, C346, C319, C320 because it’s more easy to check.
Can you see the normal waveform?

Y

Check Audio AMP ou tput

L5402,L5403,L5404,L5405
