11-2-1 Power Saving Mode (Applies to the "Settings" of the User Menu)

1. Objectives

- To enhance a sensible visual quality by maintaining an appropriate screen brightness according to the ambient brightness and
to reduce power consumption.

- To improve the power consumption efficiency when Power Saving Mode is selected.

2. Details
The CPU PW318 of the Video Board takes the current ambient brightness (in Lux units) stored in the Ambient Light Sensor of the
Power Assy., which is attached at the front of the PDP, at given intervals through SMBUS communication (identical to I2C) and
controls the PDP module to operate with the appropriate illuminance. The I2C bus is used to communicate with the PDPmodule,
and the communication method is the same as the existing communication method.

- Location of the Ambient Light Sensor

The sensor is attached to the Power Assy., which is on the front of the PDP. The location of the sensor on the Power Assy. is
displayed in the figure below. External light reaches the sensor through the guide of the Power Assy.

The screen brightness is adjusted according to the brightness measured by the Ambient Light Sensor, using the Multi APC
function (controls the number of sustain pulses according to the average signal levels) of the PDP panel, thus reducing power

consumption.

The Ambient Light Sensor IC

detects the amount of illumination.

Circuit Description

Samsung Electronics 13-5

1. Outline (PDP 42inch/50inch SMPS)
Considering various related conditions, the switching regulator with good efficiency and allowing for its small size and light weight
was used as the power supply for PDP 42inch(Schubert)/50inch(Strauss), VS requiring high power consumption Asymmetrical Half
Bridge converter and flyback converter. To comply with the international harmonics standards and improve the power factor, active
PFC(Power Factor Correction) was used to rectify AC input into +400V DC output, which in turns used as input to the switching
regulator.

2. Input
The power supply shall be capable of supplying full rated output power over free voltage ranges that are rated 100 VAC - 240 VAC
RMS nominal. Operating voltage : 90 VAC - 264 VAC
The power supply must be able to start up under peak loading at 90V AC. The power supply shall automatically recover from AC
power loss. (Note that nominal voltages for test purposes are considered to be within +/- 1.0V of nominal).
STD_5V & Vpr2(3.3V) is a SELV standby voltage that is always present when AC mains voltage present.

3. Output

4. Over Voltage Protection
The over voltage sense circuitry and reference shall reside in package that are separate and distinct from the regulator control
circuitry and reference. No single point fault shall be able to cause a sustained over voltage condition on any or all outputs.
The supply shall provide latch-mode Over Voltage Protection as defined below.

5. Short Circuit and Over current Protection
An output short circuit is defined as output impedance of less than 300mohms. The power supply shall shutdown and latch off for
shorting VS DC rails to return. Shorts between main output rails and STD_5V shall not cause any damages to the power supply.
The power supply shall either shutdown and latch off until the short condition is removed, at which point the P/S shall recover.
The power supply shall be capable of withstanding a continuous short-circuit to the output without damage or over stress to the
unit (components, PCB traces,connectors,etc.) under the input conditions specified in Section 3 above. Current Protection as
defined below.

■ Major Check Points and Waveforms

- The waveform during a Normal Operation
When the PDP set and the Logic Board are properly operating, the Operation Status LED blinks at approximately 0.8 second
interval as shown in Figure 1.
If the set is out of order, check the Operation Status LED first, and check that the output waveform is normal using an
oscilloscope.
Check if the waveform is the same as shown in Figure 2 by connecting the oscilloscope to the No. 12 TP in Figure 1. Check if
the waveform is the same as in Figure 3 by connecting the oscilloscope to the connector that is connected to the Buffer board.
If the measured waveform is different from the following waveforms, the board must be replaced.
To check the waveforms, refer to the following waveform patterns.

1. X, Y Control Block

■ Drive Circuit Definition
The Drive Circuit is a circuit that generates a waveform (high-voltage pulse) for the X and Y electrode group of the panel's external
port so as to control the panel. The high-voltage switching pulse is generated through the combination of the IC HYBRID (Drive
block + IGBT) and FET.

■ Drive Circuit Mechanism
Apicture is displayed on the PDPby applying voltage to the X, Y and ADDRESS electrodes of each pixel according to the appro­priate condition. The drive waveform applied to 42HD V4 is of the ISSS (ISSS: Interweaving Scan and Selective Sustain with Scan
IC) type and has IDS (InDependent Sustain) in the Scan section unlike the existing ADS. Discharges within a PDPpixel can be
classified into 3 types:

① Address Discharge: To form a wall voltage within the pixel by giving information (applying DATA voltage) to the pixel to be lit.
② Sustain Discharge: Sustain Discharge is a display section that voluntarily maintains the discharge of the pixels whose wall

voltage has been formed by the Address Discharge. (Optical output for displaying a picture is generated).

③ Erase Discharge: To selectively perform Address Discharge for each pixel, all pixels on the panel should be in the same status

(the wall electric charge status and space electric charge status must be the same). Therefore, the Erase
Discharge section is an important component for guaranteeing the drive margin, and is implemented by
various methods such as applying a log waveform. However, the current 42HD V4 has adopted a wall voltage
control through an RA(Repeated Auto-quenching) reset that separates the discharge area and performs
switching to perform an efficient erase operation, while the gradient was the same in the RAMP section in the
existing approach.

1) Address Discharge
Adischarge that is caused by the difference between the plus electric potential (Va apply voltage of 65~70V + Positive Wall
Charge) of the electrode and the negative electric potential (Applied GND Level + Negative Wall Charge) of the Yelectrode. The
Address discharge forms a wall voltage within the pixel to display color (to be discharged) before the Sustain Discharge period.
That is, the pixel whose wall charge has been formed by the Address Discharge forms a Sustain Discharge vis the following
Sustain pulse.

2) Sustain Discharge
ASustain Discharge is a Self-Sustaining Discharge formed by the accumulation of the electric potential of the Sustain pulse (gen­erally 200 ~ 210 Volt) alternating over the X and Yelectrodes during the sustain period, and the wall charge depending on whether
the pixel has previously been discharged or not. That is, it is controlled by the memory characteristics, one of the basic characteris­tics of the AC PDP(in that the past operating conditions determine the current status). That is, if a wall voltage exists on the pixel
(if the pixel is on), a discharge is formed again because the applied voltage, which is the sum of the following applied Sustain volt­age and the wall voltage, is higher than the discharge threshold voltage. If no wall voltage exists on the pixel (if the pixel is off), a
discharge will not occur because the Sustain voltage is not higher than the discharge threshold voltage. The Sustain Discharge
period is the period for generating actual optical output so as to display a picture on the PDP screen.

3) Erase Discharge
The purpose of a Reset (Erase) Discharge is to create uniformity of the wall voltage within all panel pixels. It evens the wall volt­ages regardless of the Sustain Discharge in the previous stage. The Erase Discharge has to remove the wall voltage introduced by
the Sustain Discharge by supplying ions or electrons by a discharge. When the wall voltage is removed through a discharge, the
time when the reverse polarity is applied to the wall voltage (fine width erasing) is to be limited or ions or electrons are to be sup­plied by a weak discharge (low voltage erasing) so as to prevent a wall charge in reverse polarity.
There are 2 known weak discharge (low-voltage) erase methods. 1) Alog waveform adopted by F company and 2) a weak erase
discharge via a ramp waveform adopted by Matsushita and other companies. Both methods control the externally applied voltage
by the difference of the wall voltage of the pixel by applying the rising gradient of the erasing waveform slowly, because the dis­charge begins when the sum of the existing remaining wall voltage and the rising waveform voltage exceeds the drive threshold
voltage. In addition, a weak discharge is introduced, because the applied voltage is low.

■ Drive Waveform Specifications

- Drive Waveform

- Description of the function of each pulse

1) Y Preset RAPulse
This is supplied to the first sub-field and erases the discharge status of the previous subfield.

2) Y Main RAPulse
During the Y Rising Ramp section, approximately 300V~350V (Vscan-h + Vset) of external voltage is supplied to the Yelectrode,
and a weak discharge is started when each gap voltage is equal to the discharge start voltage. While maintaining the weak dis­charge, as a whole, negative wall charges are accumulated on the Y electrode and positive wall charges on the X electrode and
the address electrode.
During the Y Falling Ramp section, the negative wall charges accumulated on the Yelectrode by the approximately 105V of X bias
are used to erase the positive wall charges on the X electrode, and the address electrode maintains most of the positive wall
charges accumulated during the (0V) Rising Ramp section preparing for the next address discharge.

3) Y Scan Pulse (Odd/Even)
Ascan pulse classifies the Yelectrode into Odd and Even lines and selects FPC output electrodes sequentially (one line-at-a­time). At this time, Vscan is called the Scan Bias Voltage.
AVscan voltage of approximately -175 Volt (Vsc_1) is supplied to the electrode lines. For the other lines, -56 volt (Vsc_h is higher
than Vscan-l by 120V) is supplied. However, negative wall charges are accumulated on the Yelectrode by the Ramp pulse, and
positive wall charges are accumulated on the address electrode, and the voltage applied to the cells, to which the Address pulse
(70V~75V) has been applied, becomes higher than the discharge voltage. An address Discharge occurs as a result. Since the
Scan and Data pulse is applied one line at a time as above, the address time of PDP is very long.

4) IDS Pulse (InDependent Sustain Pulse)
Since an Odd Scan is performed first, the Odd line output sustains optical twice during the IDS section. At this time, a Sustain
Discharge does not occur for the Even line because the Even line is not scanned.

5) CPS Pulse (ComPare Sustain Pulse)
By floating the Odd line that caused the Sustain Discharge in the IDS section to the Vscan-h level, and introducing the Sustain
Discharge only for Even lines, it compensates for the optical output difference between the Even and Odd lines.

6) CMS Pulse (ComMon Sustain Pulse)
Actual optical is output during the common Sustain Discharge section.

■ Mechanism of the FET Operation and High-Voltage Switching

Mechanism of the FET Operation

1) When the signal is output to the gate, (positive electric
potential) FET short circuits
(i.e. Conductor of resistance 0)

2) When no signal is output to the gate (GND), FET changes
to an open circuit (i.e. an insulator of resistance ∞).

High-Voltage Switching of the FET Operation

1) When no signal is applied to G1, FET1 is
opened and when the signal is applied to G2,
FET2 short circuits, GND is output via the output
terminal.

2) When a signal is applied to G1, FET1 short cir
cuits and when no signal is applied to G2, FET2
is opened, and 180V is output via the output
terminal.

Ambient Light Sensor

(TSL2550 Lux Calculation IC)

13-3-1 Power Saving Modes (Standard, Automatic, Super Power Saving)

1. Objective
To enhance a sensible visual quality by maintaining an appropriate screen brightness according to the ambient brightness and to
reduce power consumption.

2. Circuit Architecture

The CPU PW318 of the Video Board takes the current ambient brightness (in Lux units), stored in the Ambient Light Sensor of
Power Assy., which is attached at the front of the PDP, at given intervals through SMBUS communication (identical to I2C) and
controls the PDP module to operate with the appropriate illuminance. The I2C bus is used to communicate with the PDPmodule,
and the communication method is the same as the existing communication method.

3. Descriptions of Each Mode

1) Standard Mode
Standard Mode is set as standard visual quality.

2) Auto Power Saving Mode (Ambient Light Sensor)
This uses the TAOS 4 pin TSL2550 and is currently being used in
LCD TVs. It also uses SMBUS, which is the same type as I2C, for
communication. The Ambient Light Sensor can detect up to 1846
Lux in normal mode. The data of the sensor can be measured for
Lux operations once every 800ms.
Control is implemented by using R_ASL_GAIN. The number of
sustain pulses moves left or right as shown in the figure on the right.
For a low gradation condition, the change by R_ASL_GAIN has
been minimized considering the degradation of the visual quality.
That is, the Auto Power Saving mode screen controlled by the
ambient light sensor aims at normal video of medium gradation.

※ The following values are for a normal air signal with 80 Watt attenuation at maximum

Detected Lux R_ASL_GAIN (Address 0xE9) Remarks

0 ~ 8 250

- Read the Lux value once per second and change it the target
R_ASL_GAIN value by 5 per second according to the changed Lux
value.

- If more than 3 communication errors or saturation (count1>count0) is
detected, the default value is set (R_ASL_GAIN=128).

3) Super Power Saving Mode
This uses the Multi APC function of the PDPmodule, and aims at reducing power consumption more than 100 W for the white
pattern, which is similar to the power consumption reduction of other manufacturers.

- Concept of Multi APC

: Controls the number of sustain pulses according to the ASL(Average Signal Level) by R_P_Lower_Gain value.

In the PDP Logic, R_Multi_APC is set to 0X01, Multi_APC operates, and R_P_CM_Gain_SW is set to 0X01 so that the
upper and lower limits of the APC Table can be shifted by adjusting the R_P_Lower_Gain value only.
Therefore, the sustain pulse is controllable for the white pattern, even though it was formerly not controllable.

※ Caution: The Super Power Saving Mode screen is darker than that of Standard Mode.

Problem Descriptions

Afixed screen can cause
permanent damage to the TV
Braun tube.

Braun, PDP and LCD TVs can all be damaged. When a still image is displayed in a sequence,
this can leave stains or after-images due to the characteristics of the panel.
However, the DLPTV has the advantage that no stains or after-images are left on the screen.
The DLP TV has mirror pixels on the DMD panel that project the beam onto the screen, in
which the mirror is a digital representation of 0s and 1s, leaving no trace of light.
The mirror returns to a blank state so that no stains or after-images are left.

Confusion between the
ANYNET Port and the
SERVICE Jack Port

The SAMSUNG SKY500N model has both an ANYNETport and a SERVICE jack port.
Because the shape of the ANYNETport on the DLP TV is the same as that of the SERVICE
jack port of the SKY500N, it fails to turn the TV off after a connection has been reported.
The ANYNETport uses an RS232 port called Phone Jack, and the SERVICE jack port also
uses the RS232 port. However, you must not connect the SERVICE port and the ANYNET port.
Check if the port is the ANYNETport or the SERVICE port before connecting the port.
Even if the TV cannot be turned on after connecting, the TV will turn on if you disconnect the
connection.

Length of DVI Cable / PC RGB
Cable

- Atoo long DVI cable may cause a malfunction or degradation of the visual quality due to an
attenuation of the signal. There is no recommendation for the cable length at present.
In general, although a cable length of up to 5 meters should work, please check if video is
properly displayed on the screen after connecting. If you think the length of the cable is longer
than for normal use, check the visual quality of the video on the screen and shorten the
length, if necessary.

- This also applies to the PC RGB (D-Sub) cable. When the length of the cable is longer than
for normal use, video may not be displayed on the screen. In this case, shorten the cable
length.

When a digitally distributed TV
user receives HD-rated
broadcasts:

The digital distributed TV (Ready Technique) can render HD sources as HD-rated.
However, you need to install a set-top box for this purpose. The digital TV alone cannot render
HD broadcasting as HD-rated. Install the formal set-top box for HD broadcasts.

When a digital distributed TV
user selects normal size (4:3) to
receive SD-rated digita
broadcasts:

The digitally distributed TV (Ready Technique) renders any broadcasting service as SD-rated.
However, when connected to a set-top box, the digital TV renders HD broadcasts as HD-rated
and renders SD as SD-rated. The screen size is scaled to 4:3.

When a digitally built-in TV user
receives SD (air) broadcasting:

The digitally integrated TV ("built-in" type) renders SD broadcasting as SD-rated.
This can be understood easily.
Even a high-resolution TV cannot improve a low resolution picture into high quality.
In contrast, an SD-rated TV cannot represent HD broadcasting as HD because the resolution of
the TV is lower than the original.

When selecting a picture size of
4:3 in connection with a
computer or a multimedia
device:

The representation capability of SD or HD-rated depend entirely on the TV set. The HD TV can
render HD broadcasting as HD-rated only when it receives HD sources.
In the meantime, the HD TV renders SD as SD-rated when it receives SD sources.
The picture size has nothing to do with the resolution; TV models like SVP-XXL3HD or
SVP-XXL6HD have a size adjustment feature to 16:9, 4:3, Panorama, Zoom1, Zoom2 and Auto
Wide. This is about the aspect ratio of the top and bottom boundaries to the overall screen and
users can select their preference.

■ SD/HD broadcasts and the TV's display capability are related

1. Adigital broadcast should be transmitted in wide screen (an aspect ratio of 16:9) HD. If the broadcasting station converts a
conventional program created in normal screen (aspect ratio of 4:3) into a digital signal and broadcasts the signal, the left and
right of the picture will not be displayed.
This symptom also appears in other manufacturer's TV's. The three appliance companies are trying to resolve the problem
through the Ministry of Information and Communication.

＊ When watching an SD (normal) broadcast through a Digital (Wide) TV (480P normal broadcast)
＊ When watching an SD (normal) broadcast through a Digital Ready (Wide) TV (Using a set-top-box)
＊ When watching an analog (normal) broadcast through a wide TV

(When watching a broadcast after changing the aspect ratio of the TV from 16:9 (wide screen) to 4:3)

2. When watching a DVD title or video tape in wide screen (21:9) through a wide (16:9) TV, watching video from a computer or
game console by selecting the aspect ratio to 4:3, or watching video from a DVD, VCR, computer or game console through a
wide TV by selecting the aspect ratio to normal (4:3) or wide (21:9), the left and right, or top and bottom of the picture will not be
displayed.
This symptom appears in other manufacturer's TV's. The three appliance companies are trying to resolve the problem through
the Ministry of Information and Communication.

■ Changing the Order of the Picture Size for 16:9 Display Devices

■ Changing the Order of the Picture Size for DTV 1080i/720p Sources

■ Restrictions

1. When you want to change the picture size in PIP 'ON', you must turn the PIP off before changing the size.

However, you can change the main picture size even in PIPON for products with no restrictions.

2. When the picture size is not Normal (4:3 for 4:3 display devices, 16:9 for 16:9 display devices) and you turn PIP on, the picture

size is changed to Normal.
However, you can turn PIPon without changing the picture size for products with no restrictions.

3. In the OSD notation for the picture size, 16:9 is represented as "Wide" instead of "16:9" for devices other than with 16:9 dis

plays.
Ex: For LCD 15:9 devices, "Wide" is displayed on the OSD instead of "16:9".

4. The picture size can be changed even in the blue screen.

However, the picture size should be controlled by the product specifications if the change is impossible due to hardware
restrictions.

Virtual Channel

In digital channels, a virtual channel is used. Avirtual channel
is a function that enables users to watch a channel by selecting
a virtual channel number regardless of the region of the user.
Run Auto Channel Scan for digital broadcasts, tune in to a UHF
channel number according to the region for terrestrial broad­casts, or tune into a channel number allocated by the cable
broadcasting station for a cable TV network, and then select a
displayed virtual channel.
For example, even if you tune into channels UHF 14(MBC),
15(KBS1), 16(SBS), 17(KBS2) and 18(EBS) broadcast from
Kwanak mountain in Seoul, you can watch the channels using
virtual channels such as 11-1(MBC), 9-1(KBS1), 6-1(SBS), 7­1(KBS2) and 10-1(EBS) regardless of your region and the
actual local channel number. The virtual channel numbers may
be used nationwide, but the virtual channel numbers may vary
depending on the local broadcasting stations.
(Since the digital channel numbers may vary depending on
your region and can be changed by the broadcasting policy,
ask your local broadcasting station or regional cable TV net­work company about the channel numbers.) If the virtual chan­nel numbers are saved and the TV set can receive digital
broadcasting, you can watch a digital channel by pressing the
DTV+ button and pressing the first two digits of the correspond­ing virtual channel number.

VHF/UHF

VHF refers to TV channels 2 to 13, and UHF refers to TV chan­nels 14 to 69.

Pixels, Resolution

The pixels are the number of small dots that make up the TV screen. The resolution represents the number of pixels on a screen.
For example, if the resolution of a TV is 852x480, it means the width of the screen consists of 852 pixel columns and the height of
the screen consists of 480 pixel rows. In this case, the total number of pixels on the screen is 408,960. The more pixels there are,
the higher the visual quality that can be achieved because the picture on the screen is displayed with more pixels and therefore
with more detail.

Gradation, Color Depth

Gradation describes the number of gradual brightness levels. Since all information is represented by binary numbers in a digital
system, the Gradation is determined by the number of bits used to represent the brightness levels of a pixel on the TV screen. For
example, if a pixel is represented by 8 bits, the Gradation is 28 or 256. Since a TV uses the three primary colors of light, R, G and
B, the number of possible colors for a pixel is 256 x 256 x 256, 16,777,216, or 16.7 million colors. If 12 bits are used for a pixel, the
gradation is 212 or 4096 for a color. Since three colors R, G and B are used, 4096 x 4096 x 4096 or 68.7 billion colors are support­ed per pixel. Since 68.7 billion colors are far more than 16.7 million colors, the picture will be displayed by far more abundant and
natural colors using a 12 bit pixel. That is, since Gradation means the number of brightness levels, color represented by 4096 lev­els appears more natural than color represented by 256 levels.

Contrast

The contrast is the ratio of brightness of the brightest color to the darkest color. The contrast is calculated by dividing the bright­ness of the brightest color by the brightness of the darkest color. For example, if the brightness of the darkest color is 1 and the
brightness of the brightest color is 3000, then the Contrast is 3000/1 or 3000. Ahigher contrast means that a dark color is dis­played darker and bright color is displayed brighter so that the screen contrast can be easily distinguished. The contrast differs
from the Gradient which means the number of brightness levels.
Therefore, if someone says that a 5000:1 contrast displays a color by 5000 levels, he is confusing Contrast with Gradation.

Brightness

Brightness is the brightness per unit screen area, the unit for brightness is candela (cd). For example, 1000cd/m2 means the
brightness that is measured when 1000 candles are lit within 1 square meters area.

Color Reproductivity

Each color displayed on the TV screen is implemented by a pixel on color coordinates which have an X and Yaxis.
For example, when a pixel on the X coordinate 0.65 and the Y coordinate 0.74 is displayed as a
color and it becomes visible on the TV screen. While the possible color coordinate area is very
wide, the color coordinate area of the signal broadcast from a broadcast station is smaller than
that of possible color coordinates. Moreover, a TV provides a smaller color coordinate area than
that of the signal from the broadcasting station even though the size of the color coordinate area
varies depending on the TV model. In general, Color Reproductivity is used as follows:
The Color reproductivity of a TV is a certain % of NTSC. This means the TV displays that
particular % of the color coordinate area of the NTSC signal broadcast by the broadcasting
station. In general, a CRTTV provides the highest functional color reproductivity.

1. Make sure all protective devices are properly installed

including non-metallic handles and compartment covers
when installing or re-installing the chassis or chassis
assemblies.

2. Make sure that no gaps exist between the cabinets for

children to insert their fingers in to prevent children from
receiving electric shocks. Gaps mentioned above include
ventilation holes of a too great magnitude between the
PDP module and the cabinet mask, and the improper
installation of the rear cabinet.

Errors may occur when the resistance is below 1.0 ㏁ or
over 5.2 ㏁.

In these cases, make sure that the device is repaired
before sending it back to the customer.

3. Check for Electricity Leakage (Figure 1-1)

Warning: Do not use an insulated transformer for check­ing the leakage. Use only those current leakage testers
or mirroring systems that comply with ANSIC 101.1 and
the Underwriter Laboratory's specifications (UL1410,

59.7).

Fig. 1-1 AC Leakage Test

4. A high voltage is maintained within the specified limits

using safety parts, calibration and tolerances. When
voltage exceeds the specified limits, check each special
part.

5. Warning for Engineering Changes:
Never make any changes or additions to the circuit
design or the internal part for this product.
Ex: Do not add any audio or video accessory
connectors. This might cause physical damage.
Furthermore, any changes or additions to the original
design/engineering will invalidate the warranty.

6. Warning - Hot Chassis:
Some TV chassis are directly connected to one end of
the AC power cord for electrical reasons.
Without insulated transformers, the product can only be
repaired safely when the chassis is connected to the
earthed end of the AC power source.

To make sure the AC power cord is properly connected,
follow the instructions below. Use the voltmeter to
measure the voltage between the chassis and the
earthed ground. If the measurement is over 1.0V, unplug
the AC power cord and change the polarity before re­inserting it. Measure the voltage between the chassis
and the ground again.

7. Some TV chassis are shipped with an additional
secondary grounding system. The secondary system is
adjacent to the AC power line. These two grounding
systems are separated in the circuit using an
unbreakable/unchangeable insulation material.

8. When any parts, material or wiring appear overheated or
damaged, replace them with new regular ones
immediately. When any damage or overheating is
detected, correct this immediately and make a regular
check of possible errors.

9. Check for the original shape of the lead, especially that
of the antenna wiring, any sharp edges, the AC power
and the high voltage power. Carefully check if the wiring
is too tight, incorrectly placed or loose. Never change the
space between the part and the printed circuit board.
Check the AC power cord for possible damages. Keep
the part or the lead away from any heat-emitting
materials.

10. Safety Indication:
Some electrical circuits or device related materials
require special attention to their safety features, which
cannot be viewed by the naked eye. If an original part is
replaced with another irregular one, the safety or
protective features will be lost even if the new one has a
higher voltage or more watts.

Critical safety parts should be bracketed with ( ).
Use only regular parts for replacements (in particular,
flame resistance and dielectric strength specifications).
Irregular parts or materials may cause electric shock or
fire.

Precaution

!

1. The service instructions are printed on the cabinet, and
should be followed by any service personnel.

2. Make sure to unplug the AC power cord from the power
source before starting any repairs.
(a) Remove or re-install parts or assemblies.
(b) Disconnect the electric plug or connector, if any.
(c) Connect the test part in parallel with the electrolytic
capacitor.

3. Some parts are placed at a higher position than the
printed board. Insulated tubes or tapes are used for this
purpose. The internal wiring is clamped using buckles to
avoid contact with heat emitting parts. These parts are
installed back to their original position.

4. After the repair, make sure to check if the screws, parts
or cables are properly installed. Make sure no damage is
caused to the repaired part and its surroundings.

5. Check for insulation between the blade of the AC plug
and that of any conductive materials (i.e. the metal
panel, input terminal, earphone jack, etc).

6. Insulation Check Process: Unplug the power cord from
the AC source and turn the switch on. Connect the insu­lating resistance meter (500v) to the AC plug blade.

The insulating resistance between the blade of the AC
plug and that of the conductive material should be more

than 1 ㏁.

7. Any B+ interlock should not be damaged.
If the metal heat sink is not properly installed, no
connection to the AC power should be made.

8. Make sure the grounding lead of the tester is connected
to the chassis ground before connecting to the positive
lead. The ground lead of the tester should be removed
last.

9. Beware of risks of any current leakage coming into
contact with the high-capacity capacitor.

10. The sharp edges of the metal material may cause
physical damage, so ensure wearing protective gloves
during the repair.

11. Due to the nature of plasma display panels, partial after­images may appear if a still picture is displayed on the
screen for a long period of time.
This is caused by brightness deterioration due to the
storage effect of the panel, and to prevent this from
happening, we recommend that the brightness and con­trast are reduced.
(e.g.) Contrast: 25, Brightness: 50

Precaution

Samsung Electronics 1-3

Warning 1: First carefully read the "Safety Instruction" in this service manual.

When there is a conflict between the service and the safety instructions, follow the safety instruction at all times.

Warning 2: Any electrolytic capacitor with the wrong polarity will explode.

1-2 Servicing Precautions

1-3 Static Electricity Precautions

1. Some semi-conductive ("solid state") devices are
vulnerable to static electricity. These devices are known
as ESD. ESD includes the integrated circuit and the field
effect transistor. To avoid any materials damage from
electrostatic shock, follow the instructions described
below.

2. Remove any static electricity from your body by
connecting the earth ground before handling any
semi-conductive parts or ass'ys. Alternatively, wear a
dischargeable wrist-belt.
(Make sure to remove any static electricity before
connecting the power source - this is a safety instruction
for avoiding electric shock)

3. Remove the ESD ass'y and place it on a conductive
surface such as aluminum foil to prevent accumulating
static electricity.

4. Do not use any Freon-based chemicals.
Such chemicals will generate static electricity that
causes damage to the ESD.

5. Use only grounded-tip irons for soldering purposes.

6. Use only anti-static solder removal devices.
Most solder removal devices do not support an
anti-static feature. Asolder removal device without an
anti-static feature can store enough static electricity to
cause damage to the ESD.

7. Do not remove the ESD from the protective box until the
replacement is ready. Most ESD replacements are
covered with lead, which will cause a short to the entire
unit due to the conductive foam, aluminum foil or other
conductive materials.

8. Remove the protective material from the ESD
replacement lead immediately after connecting it to the
chassis or circuit ass'y.

9. Take extreme caution in handling any uncovered ESD
replacements. Actions such as brushing clothes or lifting
your leg from the carpet floor can generate enough static
electricity to damage the ESD.

Precaution
