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 X-RADIATION, 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 monitor is blown, replace it

with the specified.

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.

Due to high vacuum and large surface area of picture tube,

extreme care should be used in handling the Picture Tube.

Do not lift the Picture tube by it's Neck.

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 exposed 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 specified, there is

possibility of shock hazard and the set must be checked and

repaired before it is returned to the customer.

Leakage Current Hot Check circuit

AC Volt-meter

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 1MΩ and 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.

ADJUSTMENT INSTRUCTION

1. Application Range

This spec. sheet applies to PB12K Chassis applied PDP TV

all models manufactured in TV factory.

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. But it is

flexible when its factory local problem occurs.

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

25 cC ± 5 cC of temperature and 65 % ± 10 % of relative

humidity if there is no specific designation.

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

50 / 60 Hz.

(5) Before adjustment, execute Heat-Run for 5 minutes.

V After Receive 100% Full white pattern (06CH) then

process Heat-run

(or “8. Test pattern” condition of Ez-Adjust status)

V How to make set white pattern

1) Press Power ON button of Service Remocon

(3) White Balance Adjustment

- If you can’t adjust with inner pattern, then you can adjust

it using HDMI pattern. You can select option at “Ez-Adjust

Menu – 7. White Balance” there items “NONE, INNER,

HDMI”. It is normally setting at inner basically. If you can’t

adjust using inner pattern you can select HDMI item, and

you can adjust.

- In manual Adjust case, if you press ADJ button of service

remocon, and enter “Ez-Adjust Menu – 7. White Balance”,

then automatically inner pattern operates. (In case of

“Inner” originally “Test-Pattern. On” will be selected in The

“Test-Pattern. On/Off”.

O Connect all cables and equipments like Pic.5)

O Set Baud Rate of RS-232C to 115200. It may set

115200 orignally.

O Connect RS-232C cable to set

O Connect HDMI cable to set

O When Color temperature (White balance) Adjustment

(Automatically)

- Press “Power only key” of service remocon and

operate automatically adjustment.

- Set BaudRate to 115200.

O You must start “wb 00 00” and finish it “wb 00 ff”.

O If it needs, then adjustment “Offset”.

(4) White Balance Adjustment (Manual adjustment)

1) Test Equipment: CA-210

- Using PDP color temperature, Color Analyzer (CA-

210) must use CH 10, which Matrix compensated

(White, Red, Green, Blue compensation) with CS-

2100. See the Coordination bellowed one.

2) Manual adjustment sequence is like bellowed one.

- Turn to “Ez-Adjust” mode with press ADJ button of

service remocon.

- Select “10.Test Pattern” with CH+/- button and press

enter. Then set will go on Heat-run mode. Over 30

minutes set let on Heat-run mode.

- Let CA-210 to zero calibration and must has gap more

10cm from center of PDP module when adjustment.

- Press “ADJ” button of service remocon and select

“7.White-Balance” in “Ez-Adjust” then press “G” button

of navigation key. (When press “G” button then set will

go to full white mode)

- Adjust at three mode (Cool, Medium, Warm)

- If “cool” mode

Let B-Gain to 192 and R, G, B-Cut to 64 and then

control R, G gain adjustment High Light adjustment.

- If “Medium” and “Warm” mode Let R-Gain to 192 and

R, G, B-Cut to 64 and then control G, B gain

adjustment High Light adjustment.

- All of the three mode

Let R-Gain to 192 and R, G, B-Cut to 64 and then

control G, B gain adjustment High Light adjustment.

- With volume button (+/-) you can adjust.

- After all adjustment finished, with Enter (_ key) turn to

Ez-Adjust mode. Then with ADJ button, exit from

adjustment mode

* Attachment: White Balance adjustment coordination and color

6. Test of RS-232C control.

- Press In-Start button of Service Remocon then set the “4.Baud

Rate” to 115200. Then check RS-232C control and

7. Selection of Country option.

- Selection of country option is allowed only North American

model (Not allowed Korean model). It is selection of Country

about Rating and Time Zone.

(1) Models: All models which PB82C Chassis (See the first

page.)

(2) Press “In-Start” button of Service Remocon, then enter the

“Option” Menu with “PIP CH-“ Button

(3) Select one of these three (USA, CANADA, MEXICO)

defends on its market using “Vol. +/-“button.

Caution : Don’t push The INSTOP KEY after completing the

function inspection

Caution : Inspection only PAL M / NTSC

8. GND and ESD Testing

8-1. Prepare GND and ESD Testing.

- Check the connection between set and power cord

8-2. Operate GND and ESD auto-test.

(1) Fully connected (Between set and power cord) set enter

the Auto-test sequence.

(2) Connect D-Jack AV jack test equipment.

(3) Turn on Auto-controller(GWS103-4)

(4) Start Auto GND test.

(5) If its result is NG, then notice with buzzer.

(6) If its result is OK, then automatically it turns to ESD Test.

(7) Operate ESD test

(8) If its result is NG, then notice with buzzer.

(9) If its result is OK, then process next steps. Notice it with

Good lamp and STOPER Down.

8-3. Check Items.

(1) Test Voltage

GND: 1.5KV/min at 100mA

Signal: 3KV/min at 100mA

(2) Test time: just 1 second.

(3) Test point

- GND test: Test between Power cord GND and Signal

cable metal GND.

- ESD test: Test between Power cord GND and Live and

neutral.

(4) Leakage current: Set to 0.5mA(rms)

9. POWER PCB Ass’y Voltage
