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 lsolation 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 circuitary that may be

inadvertently introduced during the service operation.

If any fuse (or Fusible Resistor) in this monitor is blown, replace it

with the same specified type.

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.

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 positioin, 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 esposed 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 sepcified, there is

possibility of shock hazard and the set must be checked and

repaired before it is returned to the customer.

6-3. White Balance Adjustment Method

Basically it uses the internal pattern but when internal pattern

is not possible, you can select HDMI input for adjustment.

Through the option at the most bottom part of the Ez Adjust

Menu 7.White Balance menu, you can select NONE, INNER

and HDMI, and the default is set to INNER. When the

adjustment cannot be done with the internal pattern, you can

select HDMI input for adjustment.

For manual adjustment, press the ADJ KEY of the adjustment

R/C to enter Ez Adjust 7.White-Balance, and the pattern is

automatically displayed. (When you set the Option to INNER,

the default is always set to INNER)

(1) Connect the set according to the internal pattern or HDMI

input in accordance with measuring device connection

diagram.

(2) Set the Baud Rate of RS-232C to 115200. It is set to

115200 as default.

(3) Connect the RS-232C Cable to the set.

(4) Connect the HDMI Cable to the set. (Limited to the set with

HDMI option)

ADJ KEY on the Service R/C. Then enter adjustment mode

by pressing the Right KEY (

) .

(The internal pattern of full white appears by pressing

)

(6) The adjustment is conducted in three levels of color

temperature; COOL, MEDIUM, and WARM.

Adjust G gain and B gain with decreasing Default values

from 192

-When B Gain is Fixed at Default value(192)

Adjust R gain and G gain with decreasing Default values

from 192

-When G Gain is Fixed at Default value(192)

Adjust R gain and B gain with decreasing Default values

from 192

One of R/G.B Gain should be fixed at 192 and adjust two

Gain Value with decreasing the Default values from 192.

(7) Use the Vol. +, - key for adjustment.

(8) When the adjustment is completed, press the ENTER (Á
