Problem Descriptions
A fixed 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 DLP TV 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.
Length of DVI Cable / PC RGB
Cable
- A too 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.
Reference Information
14-2 Samsung Electronics
■ SD/HD broadcasts and the TV's display capability are related
1. A digital 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 PIP ON 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 PIP on 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. A virtual 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.

S-VIDEO IN Port
This is called super video. S-Video is a type of video signal
which has the video luminance and the color signal separated
in order to provide better visual quality.
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. A higher 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 Y axis.
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 CRT TV provides the highest functional color reproductivity.

13-2 Partial Block Description
13-2-1 Main SMPS
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/50inch, 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 with +/- 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
① 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 of all outputs.
The supply shall provide latch-mode Over Voltage Protection as defined below.
