3-D HDTV With DLP

3D is an exciting new feature for the home theater market. For some dramatic movies or soap operas, 3D might seem out of place. But for sports, action movies, etc. 3D makes as much difference as color vs. black and white. And the new 3D technology is superior to the 3D system that has been used in theaters.

The commercial successes of recent 3D films like "Beowulf", "Meet the Robinsons", and "Journey to the Center of the Earth", is sparking interest with the movie studios to produce more 3D content material. Disney, Universal, Philips, Samsung, Sony, Thomson and IMAX are currently exploring the potential 3D HDTV market. Disney said it would begin making all its computer-animated films in 3D. According to Dreamworks CEO Jeffrey Katzenberg, all of the major studios have 3D projects under way. There will be over 2,500 theatre screens equipped with the Digital 3D technology by the end of 2009. All of this content will be available to the home theater market. The Big Question: will the 3D market be pervasive enough for major networks, especially the sports subset, to broadcast in 3D?

3D Distribution

3-D HDTV With DLP

It will likely be the satellite TV companies like DirecTV and Dish Network that distribute 3D versions of HDTV programming first. 3D movies should take about the same bandwidth as other 120 fps (frame per second) high def movies. The satellite companies have enough broadcast bandwidth to support niche markets (the cable companies do not), and for now, 3D HDTV is a niche market.

"Satellite's going to be constrained not so much by how many channels they can carry than by how many they can get," said Bob Scherman, Satellite Business News.

By 2010, it is projected that 60% of TV receivers in the United States will use a satellite signal, up from 15% in 2002.

3D HDTV Home Theater Systems

Because of the high frame rate for 3D, and the need for synchronization, LCD screens are generally incompatible with advanced 3D. However, prototypes by Phillips have been demonstrated at upwards of ,000, and this technology does not require glasses. The Phillips technology is optically very complicated. Unlike electronics, it cannot be assumed that the price will come down.

By the end of this year (2008), more than one million 3D ready DLP HDTVs, manufactured by Mitsubishi and Samsung, will have been sold in the U.S. The technology functions by supplying a 60 Hz signal to each eye (equivalent to 120 Hz total). These sets can display standard HDTV, and are compatible with 3D material. Some source material is available for download, and Blu-Ray 3D discs are becoming available. "Hannah Montana and Miley Cyrus: Best of Both Worlds Concert" was the first 3D Blu-ray Disc.

The Glasses: Field Sequential 3D

Special glasses are used with the DLP 3D system. The system is called "Field Sequential 3D" or HQFS (High Quality Field Sequential). This technology uses electronic shutter glasses instead of red-blue lenses we are used to at the movies. The effect is definitely superior. Our eyes see a slightly offset view of a scene. The two slightly different views are combined by the brain to result in our ability to see in 3D. Field Sequential 3D simulates this experience with shutter glasses. The shutter is not mechanical, but instead an LCD filter, that blocks vision when the opposite eye's view is shown.

A HDTV set with 120 Hz refresh rate is recommended for 3D viewing. The 3D system uses half of the total information for each eye. If we use a TV with a total of 60 Hz refresh rate, it would supply only 30 Hz to each eye, and that refresh rate would be visible (flicker).

When designing a 3D system with previous 3D techniques, we have the choice of either sending two equal bandwidth signals with full information, effectively doubling the signal bandwidth, or sending the signal such that either the horizontal or vertical resolution is halved, one half for each eye. Doubling the bandwidth would be a problem since the HDTV signal bandwidth capacity is already at a premium. Using the same bandwidth as non-3D material means that we can utilize the technology with current HDMI or DVI interfaces.

The alternative to cut resolution is unattractive, since we have worked to so hard to increase our system to high definition, we don't want to compromise. By using alternate frames for each eye, we see a high definition signal without flicker.

Two sets of wireless shutter glasses, with a control transmitter (InfraRed (IR), the same technology as the TV's remote control) cost about 0.

"Hang-Ups" Holding up DLP

Many consumers have a fascination with the idea of hanging their new big screen HDTV on the wall, like a painting. It's worth noting that most LCD and Plasma big screen TVs never actually get mounted on the wall. It is a significant challenge to mount something that weighs 60-150 pounds on the wall, and once installed, it's a continuing challenge for maintenance (for example, a 50 inch Pioneer PDP-5070HD weighs 128 pounds).

According to the NPD Group, only 13 percent of current LCD TV owners and 25 percent of plasma TV owners have their set mounted on the wall.

DLP is very popular among those who want larger high picture quality screens at affordable prices. For the money, DLP easily provides the highest quality-size value. An LCD of the same size and price will not have the picture quality of a DLP. DLP is also available in larger screen sizes then LCD televisions.

However, a DLP rear projection TV is a few inches thicker than an LCD or Plasma screen. LCD screens are usually 7-10 inches thick; DLP sets are usually 12-17 inches thick. Because of the fascination with mounting their sets on the wall, this difference of a few inches becomes the deciding factor for many consumers' purchase decisions.

Texas Instruments, who manufactures the DLP chips in a foundry in South Korea, sees renewed potential for the technology, which uses tiny mirrors on a semiconductor. The new LED Light Engine call "Phlatlight" (manufactured by Luminus) replaces the arc lamp and color wheel design of previous DLP HDTVs. Samsung has had their own proprietary LED lamp system for a couple of years. The LED Light Engine will need to be replaced infrequently (unlike the cold-cathode fluorescent lamps that had to be replaced every few years).

DLP HDTVs with an LED engine are more energy efficient than comparably sized flat panel displays, and the lack of a moving color wheel in the design means they perform with less noise. The DLP chip is faster than any other HDTV technology, with the mirrors switching on and off more than 15,000 times per second to deliver a picture without blur for fast moving images such as sports.

DLP HDTV sets are a very smart choice for most people, but be selective. Many of the HDTV sets in stores still do not have important technology, such as LED backlights.

The compatibility of the TV for 3D can be verified by looking for an input on the back of unit, marked "3D Ready".

Home Theater Personal Computer (HTPC)

An important trend in the home theater is the integration of the personal computer (PC) with the home theater. Integrating a PC into your home entertainment center has many advantages in addition to enabling 3D video. Downloading movies is one of the advantages. The HTPC should have a graphics card with a DVI connector (Digital Video Interface). Both XP and Vista will support Microsoft's product for the home theater.

HDTV and 3D video is computation intensive, meaning a high-performance computer. For 720p videos, a dual core microprocessor is needed; 1080p or 1080i videos require a quad core microprocessor for smooth playback. Video files are very large (!), so the larger the hard-drive, the better.

DirectX 9 graphics drivers (software) need to be installed, if they are not already present. To find your current version, Click "START" and then "RUN" from your Windows desktop. Type "dxdiag" in the "Run" box.

Software is available from several different vendors; "StereoPlayer" (Version 1.3.4) from 3DTV.at is available. Purchase of StereoPlayer is about . While you are at 3DTV.AT also download the GPL MPEG-1/2 Decoder. Alternatives to Stereoplayer include "Dynamic Digital Depth" (ddd.com), "Stereoscopic Player" and "Tridef Visualizer".

Summary

3D technology has become a major force in Hollywood. It is probable that this trend will repeat in the home theater. CRT and DLP work best with 3D technology, though plasma systems are also available. DLP offers the better value for big screens using HDTV, not just 3D HDTV.

The New Samsung UN55b8500 1080p LCD HDTV - Television Redefined

Once again Samsung raises the bar by creating a breakthrough that makes for a much more intense TV viewing experience. From sports to your favorite movies, the Samsung UN55B8500 takes TV watching to another level. Not only does the new Samsung model represent a leap in how you watch TV, but also on how you interact with the television.

Yes, First Impressions Count... And The UN55B8500 Delivers

What strikes you first, as you come face to face with the new Samsung model, is its sleek shape and look. Samsung has done a fantastic job of squeezing in incredible quality features into it's razor-thin 1.6 inches deep frame supported by a very unique looking stand with an elegantly clear neck. It may be slim but this TV packs a 7,000,000 to 1 dynamic contrast ratio for a brighter, sharper and bolder look that doesn't disappoint. The UN55B8500 television set uses LED local backlight dimming tech.

The New Samsung UN55b8500 1080p LCD HDTV - Television Redefined

If you're looking to put this television on a wall, then the people at Samsung have provided the optional Wall Mount that lets you hang it just like a picture frame. When mounted, this TV looks more like a delicate work of art, than your average hum-drum TV. I tend to like mine hanged, but it looks good on a stand also.

The Action, Colors and Clarity

The images become very true to life because of the work Samsung has done in the Color, Contrast and Clarity department. Rich, deep blacks that were unavailable up until now on an LCD screen, pure whites and the 7 million to one contrast ratio works to make the picture breathtaking.

Because of the Advanced Color Processing capabilities of this TV, the Samsung UN55B8500 has a greater depth and vibrant color that captivates the viewers, even with the subdued color palette. On top of this, the Auto Motion Plus 240Hz technology eliminates all motion blur. This results in a crisp, clear and smooth picture no matter how much fast action there is on the screen.

Wide Color Enhancer Pro and the Auto Motion Plus 240Hz

Samsung really paid attention to the way images are shown on the screen, and this resulted in very fluid and clear action. You can see the details, even when the action is really fast. The result is great depth of detail that other TVs don't seem to have. Every pixel on the screen is taken and analyzed by the Wide Color Enhancer. Then it is stretched to it's 3D limit. This creates full and lifelike colors on the screen. The picture really seems to pull you in with it's realness.

The World Wide Web On The Samsung UN55B8500

Samsung makes it easy to surf the net right on your TV. The set has widgets with which you can add, delete and watch content. You can view it all on the roomy sidebar or across your wide screen. I have to admit that I did not get this feature at first until I started using it and saw the advantages. No longer did I have to go and do the old shuffle between the TV and computer when I wanted to look up some info I heard from the TV. Now I can do it all in one place.

Get On TV

It seems the people at Samsung really paid attention to the fact that most of us want to access our photos, music and videos on our TV. Now you can do exactly that on the UN55B8500. You have access to your DLNA or PC wirelessly. You can enjoy YOUR content on your TV. You can even link to multiple PC's - as is the case for a full family where everybody has their own computer. You also don't need to leave your content on your storage devices. The UN55B8500 comes with USB: 2.0 Multi-Media Center. The user friendly interface allows you access to videos, playlists and photos with your remote.

Using Your TV For Content

Here's yet another feature. Again, I thought it was a silly feature at first, but I quickly changed my oppinion when I actually put it to use.You can use your Samsung UN55B8500 to download and save content so you can view it later. This came in handy when I had to open my laptop and I posted the instructions on how to do it (which I found online) on the screen while I was doing it.

Conclusion

Samsung has done an outstanding job with the new UN55B8500 55-inch 1080p LED HDTV. It's really hard to find faults with this TV. The picture is incredible. It's also full of useful and well thought out options. If you're looking for a big screen that really delivers, then the UN55B8500 is what you need.

Samsung 153V LCD Monitor Netzteil Reparatur-Tipps

Fehlerbehebung Samsung LCD 153V Netzteil ist wie Fehlerbehebung die CRT-Typ. Dieser Monitor kam mit keinen Strom Symptom. Wenn Sie zum ersten Mal die Reparatur dieser Art der Stromversorgung sind, empfehle ich Ihnen, zuerst die Schaltnetzteil Trafo. Dann testen Sie jede einzelne Komponente im primären Bereich, bevor Sie an den sekundären Abschnitt überprüfen fortsetzen. Sie haben gut zu sein in Tests grundlegenden elektronischen Komponenten, um die Fehler zu erkennen.

Sie könnenalways browse through my website just in case you do not know how to test basic electronic components. If you do not know the right way to check, you might miss out a bad component and this will lead you not able to solve the problem. After carefully checking all the components in the power supply section, I found the filter capacitor do not have any reading using digital capacitance meter (open) , the two round type fuse also open circuit, 1N4744 15 Volt zener diode short circuit and lastly the power ic TOP247F blown! Testing the switch mode power supply primary winding with a dick smith flyback tester shown green bar which indicated good winding.

What we left here were the secondary diode and filter capacitor. Upon checking them with analog meter and esr meter, found all of them to be good condition. Other area like main board and inverter board also looks okay (Power failure rarely affect these two circuit). Now we have confirmed that only five components found to be faulty. One by one the components were replaced (except one fuse) and just before you switch on the power supply, make sure you connect a 100 watt light bulb across the live ac line-refer to the photo at my website. Once it is done you can then proceed to switch on the LCD monitor to look at the brightness of the bulb.

Samsung 153V LCD Monitor Netzteil Reparatur-Tipps

If it very bright, this suggests that there are still short circuit somewhere in the power section. If it dim or totally goes off, you can now place your red probe to the secondary side to check if any dc present at their respective line. If there are DC voltages present at the output, you can switch off the power, discharge the filter capacitor (for safety purposes), remove the light bulb and connect back the new fuse to its original location.

You are now hundred percent sure that the LCD power supply won't blow once you switch it on. By the way the filter capacitor is rated at 105 Celsius and you cannot replace it with the 85 Celsius type otherwise it may open up again after using for couple of weeks or months. The ventilation in LCD monitor is not as good as the cathode ray tube monitor, because the power supply is fully covered by a large aluminum plate and it can get hot pretty fast. Conclusion, whether you are repairing Samsung 153V LCD power supply or other brand of LCD monitor, the procedure is the same. Who knows the power problem in this monitor is a common fault and in the future you can tackle this brand of power supply in the shortest time. To measure electronic components is not that difficult, but to get the original parts like the power ic will consume you lots of time.

Samsung LCD 510bn Secrets Puissance réparation Supply

La plainte de ce moniteur LCD Samsung 510BN avait pas d'électricité, après que le couvercle a été ouvert, je trouve que le condensateur de puissance du filtre détiennent toujours une certaine charge et la tension est assez élevée. Un bon moniteur de plein droit la tension stockée de filtre du condensateur doit être de décharge en moins de 10 secondes. Cela indique qu'il y avait quelque chose de pas bon dans le circuit. S'il vous arrive de réparer ce type de problème d'alimentation, assurez-vous décharger le condensateur premier filtre avant de vérifieron others components. After the filter capacitor voltage already discharged , I used dick smith flyback tester to measure across the primary winding of the switch mode power transformer to see if there are any short circuit occurred.

The result of the test was the flyback tester LED light all goes off which means there must be components shorted either in the primary or secondary section, sometimes the primary winding can go shorted also. A shorted power ic (this monitor is using the 4 pins 5L0365R power ic) in the primary section or a shorted diode in the secondary section would pull down the flyback tester LED bar to the minimum.

If the flyback tester LED have 8 full bars, this means that the components such as power ic (power fet if have), power transformer primary winding and all the secondary diodes are not shorted. To isolate if the shorts is either in the primary or secondary section, you must desolder the power transformer. Check the primary winding of the power transformer off board first before you test on all the secondary diodes using analog meter set to times 10 K ohm.

A shorted diode will show two reading registered at the analog meter. In this Samsung 510bn LCD monitor power supply, the caused of the no power and filter capacitor take longer time to discharge was due to a shorted secondary diode which is from the schottky type with the part number of SB5H100. Searching the internet, I found this diode technical datasheet; it is a 100Volt 5A schottky diode. This shorted diode is located at the 12 volt rail which means it converts the ac to 12 Volt dc.

After the replacement the LCD monitor work perfectly fine! Whether you are troubleshooting the Samsung 510BN Lcd monitor power supply or any type of switch mode power supply, basically the procedure of testing it is the same. Of course there are many more methods to locate the shorted secondary diode such as directly test the diodes, but this method can check for components shorted even without touching the soldering gun.

This means, if the flyback tester shown 8 full bars, then don’t waste your time to test on all the secondary diodes again. Get one dick smith flyback tester and you could see how valuable this meter is in performing variety test for you such as checking the computer monitor B+ coil, flyback transformer, crt horizontal yoke coil, ballast and many more.
