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 theservicing 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.

ADJUSTMENT INSTRUCTION

1. Application RangeThis spec. sheet applies to PB23A 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 °C ± 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 AC 100-240

V~, 50/60 Hz.

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

■ Afte r Receive 100% Ful l white pattern (06CH) then

process Heat-run

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

■ How to make set white pattern1) Press Power ON button of Service Remocon

2) Press ADJ button of Service remocon. Select “10. Test

pattern” and, after select “White” using navigation

button, and then you can see 100% Full White pattern.

* In this status you can maintain Heat-Run useless any

pattern generator

* Notice: if you maintain one pic ture over 20 minutes

(Especially sharp distinction black with white

pattern – 13Ch, or Cross hatch pattern – 09Ch)

then it can appear image stick near black level.

■ 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, andyou 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”.

- Press “ADJ” button of service remocon and select

“7.White-Balance” in “Ez-Adjust” then press “►” button of navigation key. (When press “►” 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

● When tester will measure on Cool condition, adjust W30 onTV display menu.

● When tester will measure on medium condition, adjust 0 on

TV display menu.

● When tester will measure on warm condition, adjust W30 on

TV display menu.

● Using CA-210 Equipment. (10 CH)

- Contrast value: 216 Gray

- Brightness spec.

5.3. 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

5.4. 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.

■ Models: All models which PU11A Chassis (See the rst

page.)

6. GND and ESD Testing

6.1. Prepare GND and ESD Testing.■ Check the connection between set and power cord

6.2. Operate GND and ESD auto-test.■ Fully connected (Between set and power cord) set enter the

Auto-test sequence.

■ Connect D-Jack AV jack test equipment.

■ Turn on Auto-controller(GWS103-4)

■ Start Auto GND test.

■ If its result is NG, then notice with buzzer.

■ If its result is OK, then automatically it turns to ESD Test.

■ Operate ESD test

■ If its result is NG, then notice with buzzer.

■ If its result is OK, then process next steps. Notice it with

Good lamp and STOPER Down.

6.3. Check Items.■ Test Voltage

● GND: 1.5KV/min at 100mA

● Signal: 3KV/min at 100mA

■ Test time: just 1 second.

■ 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.

■ Leakage current: Set to 0.5mA(rms)

1 Currently installed programsCheck the LG Pentouch Multi-touch Driver or Pentouch TV

2 Check USB Dongle Driver in Device Manager-LG Pentouch Multi-touch Driver(MultiTouch)-LG PentouchMulti-touch Driver(BUS)-LG Pentouch Multi-touch Driver(Dongle)

the Dongle Driver should be displayed when connected USB Dongle

Pen

The photo sensor in thepen detect the light

PlasmaDisplay

Principle 1. The Pen using PDP Cell’s ligh t energyStep 1. The pen detect the PDP Cell’s lightStep 2. The pen convert detected light to voltageStep 3. The pen calculate X,Y posit ionStep 4. The pen transfer the X,Y data through RF

USB

Dongle

RF Wireless communication(2.4GHz)

Principle 2. The position data processed Pentouch TV Application looks like PC mouse.Step 1. USB Dongle receive the position data.Step 2. USB Dongle Driver parsing the positonStep 3. Pentouch TV application drawing and click function.Step 4. The result was displayed PDP TV through HDMI orRGB cable.

The HDMI or RGB signal is PC’s output that configuration set by clone mode.

It can use Multi-Touch funct ion by support 2 pens.

Pentouch TV Application- It was developed by LG.- It can be using internet for web surfing , Flash Game etc.
