Problem Descriptions

A fixed screen can causepermanent damage to the TVBraun 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, inwhich 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 RGBCable

- 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 TVuser receives HD-ratedbroadcasts:

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 renderHD broadcasting as HD-rated. Install the formal set-top box for HD broadcasts.

When a digital distributed TVuser selects normal size (4:3) toreceive SD-rated digitabroadcasts:

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-ratedand renders SD as SD-rated. The screen size is scaled to 4:3.

When a digitally built-in TV userreceives 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 ofthe TV is lower than the original.

When selecting a picture size of4:3 in connection with acomputer or a multimediadevice:

The representation capability of SD or HD-rated depend entirely on the TV set. The HD TV canrender 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 orSVP-XXL6HD have a size adjustment feature to 16:9, 4:3, Panorama, Zoom1, Zoom2 and AutoWide. This is about the aspect ratio of the top and bottom boundaries to the overall screen andusers can select their preference.

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 aconventional 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 displays.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 hardwarerestrictions.

VESA Plug & PlayThis function enables the automatic recognition of deviceswhen connecting the TV to the computer without additional set-tings.

S-VIDEO IN PortThis is called super video. S-Video is a type of video signalwhich has the video luminance and the color signal separatedin order to provide better visual quality.

VHF/UHFVHF refers to TV channels 2 to 13, and UHF refers to TV chan-nels 14 to 69.

Pixels, ResolutionThe 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 ofthe 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 thereforewith more detail.

Gradation, Color DepthGradation describes the number of gradual brightness levels. Since all information is represented by binary numbers in a digitalsystem, the Gradation is determined by the number of bits used to represent the brightness levels of a pixel on the TV screen. Forexample, 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 andB, 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, thegradation 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 support-ed per pixel. Since 68.7 billion colors are far more than 16.7 million colors, the picture will be displayed by far more abundant andnatural colors using a 12 bit pixel. That is, since Gradation means the number of brightness levels, color represented by 4096 lev-els appears more natural than color represented by 256 levels.

ContrastThe contrast is the ratio of brightness of the brightest color to the darkest color. The contrast is calculated by dividing the bright-ness of the brightest color by the brightness of the darkest color. For example, if the brightness of the darkest color is 1 and thebrightness of the brightest color is 3000, then the Contrast is 3000/1 or 3000. A higher contrast means that a dark color is dis-played darker and bright color is displayed brighter so that the screen contrast can be easily distinguished. The contrast differsfrom 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.

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

Color ReproductivityEach 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 acolor and it becomes visible on the TV screen. While the possible color coordinate area is verywide, the color coordinate area of the signal broadcast from a broadcast station is smaller thanthat of possible color coordinates. Moreover, a TV provides a smaller color coordinate area thanthat of the signal from the broadcasting station even though the size of the color coordinate areavaries 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 thatparticular % of the color coordinate area of the NTSC signal broadcast by the broadcastingstation. In general, a CRT TV provides the highest functional color reproductivity.

Circuit Description

Normal WaveformWhen the Operating LED blinks normally (at 0.5 second intervals), which indicates the normal operation of the PDP Set and LogicBoard, and the V-SYNC and data output signals are normal.

If the set is out of order, perform troubleshooting according to the procedures below.1) Visual Inspection : Check if the Operating LED on the Logic Main blinks at a 0.5 second interval. If the Operating LED blinks too fast or too slow, you have to reload the data onto the MICOM, as this indicates abnormal

data processing in the MICOM. To load the data, supply power to the module and load the data using GA-WRITER.2) If no problem has been found through the visual inspection, check if the drive waveforms and the address data output are

normal. (Check Point: Check the DAMPING R-NET output of each data output terminal.) If no drive waveform or address output signal is detected, load data onto the MICOM according to the procedures described

above, as this indicates a MICOM data error. If data output is detected but is abnormal, it indicates a hardware short-circuit if measured for the drive waveform, or it

indicates abnormal data output due to the abnormal operation of the DDR memory caused by the abnormal Vref voltage if measured in the address data. Abnormal data output due to the abnormal operation of the DDR memory or a short circuit onthe board, which may be caused during the ass'y process, causes the screen to be abnormally displayed. Therefore, you have to conduct a short test for each part.

If the Vref voltage (Voltage Divider Voltage) is lower than 1.25V, check the resistance of the resistance output part and checkif the circuit status is normal. This applies the voltage and the proper Vref voltage and results in the screen being properlydisplayed.

If the screen is abnormally displayed, even though the Vref voltage is normal, find any abnormal points by conducting a shorttest. If a short circuit is found and it is repairable, repair it. If a short circuit is internal, replace the board.

The following waveform appears when the V-sync and address data are output properly.

< Normal V-SYNC Output Waveform > < Normal Address Data Output Waveform >

About Logic BoardThe Logic Board consists of a Logic Main board, which processes the video signal input through LVDS and creates the addressdriver output and XY drive signals, and a Buffer board, which buffers the output signal and outputs the signal to the Address Driver IC (TCP IC).

2. X, Y Control Block

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

Drive Circuit MechanismA picture is displayed on the PDP by applying voltage to the X, Y and ADDRESS electrodes of each pixel according to the appro-priate condition. The drive waveform applied to 42HD V4 is of the ISSS (ISSS: Interweaving Scan and Selective Sustain with ScanIC) type and has IDS (InDependent Sustain) in the Scan section unlike the existing ADS. Discharges within a PDP pixel can beclassified 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 byvarious 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 DischargeA discharge that is caused by the difference between the plus electric potential (Va apply voltage of 65~70V + Positive WallCharge) of the electrode and the negative electric potential (Applied GND Level + Negative Wall Charge) of the Y electrode. TheAddress 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 followingSustain pulse.

2) Sustain DischargeA Sustain Discharge is a Self-Sustaining Discharge formed by the accumulation of the electric potential of the Sustain pulse (gen-erally 200 ~ 210 Volt) alternating over the X and Y electrodes during the sustain period, and the wall charge depending on whetherthe pixel has previously been discharged or not. That is, it is controlled by the memory characteristics, one of the basic characteris-tics 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 volt-age and the wall voltage, is higher than the discharge threshold voltage. If no wall voltage exists on the pixel (if the pixel is off), adischarge will not occur because the Sustain voltage is not higher than the discharge threshold voltage. The Sustain Dischargeperiod is the period for generating actual optical output so as to display a picture on the PDP screen.

3) Erase DischargeThe purpose of a Reset (Erase) Discharge is to create uniformity of the wall voltage within all panel pixels. It evens the wall volt-ages regardless of the Sustain Discharge in the previous stage. The Erase Discharge has to remove the wall voltage introduced bythe Sustain Discharge by supplying ions or electrons by a discharge. When the wall voltage is removed through a discharge, thetime when the reverse polarity is applied to the wall voltage (fine width erasing) is to be limited or ions or electrons are to be sup-plied 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) A log waveform adopted by F company and 2) a weak erasedischarge via a ramp waveform adopted by Matsushita and other companies. Both methods control the externally applied voltageby the difference of the wall voltage of the pixel by applying the rising gradient of the erasing waveform slowly, because the dis-charge begins when the sum of the existing remaining wall voltage and the rising waveform voltage exceeds the drive thresholdvoltage. In addition, a weak discharge is introduced, because the applied voltage is low.

While maintaining the weak dis-charge, as a whole, negative wall charges are accumulated on the Y electrode and positive wall charges on the X electrode andthe address electrode.During the Y Falling Ramp section, the negative wall charges accumulated on the Y electrode by the approximately 105V of X biasare used to erase the positive wall charges on the X electrode, and the address electrode maintains most of the positive wallcharges accumulated during the (0V) Rising Ramp section preparing for the next address discharge.

3) Y Scan Pulse (Odd/Even)A scan pulse classifies the Y electrode into Odd and Even lines and selects FPC output electrodes sequentially (one line-at-a-time). At this time, Vscan is called the Scan Bias Voltage.A Vscan voltage of approximately -175 Volt (Vsc_1) is supplied to the electrode lines. For the other lines, -56 volt (Vsc_h is higherthan Vscan-l by 120V) is supplied. However, negative wall charges are accumulated on the Y electrode by the Ramp pulse, andpositive 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 theScan 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 SustainDischarge 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 SustainDischarge 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.

Circuit Description

Samsung Electronics 13-9

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 circuits and when no signal is applied to G2, FET2 is opened, and 180V is output via the outputterminal.
