They used shutter glasses and an ir emitter to synchronize the shutter glasses with the image being displayed, just as they do today. They only had a dongle attached to a monitor and some software to produce the 3d image. The monitor its self was just a simple off the shelf monitor that you could purchase anywhere. The key was the hardware driving the monitor. So then why can&rsquo;t we buy a 3d blu ray player and connect it to our hd television and see 3D? Personally I believe it has to do with marketing. They want to sell new televisions even to people who just purchased that new flat panel television, so to drive business you now need a 3D tv to view 3D pictures, it sounds logical and easy to sell. After a while when the market becomes saturated they will start producing &ldquo;new&rdquo; technology that will allow you to watch 3D movies on your old non-3D set.

First of all component level repair is virtually impossible. The same set with the same model number may have different components depending on where it was made. In most all the manufacturers sets that I have worked with, the serial number range will determine the parts needed for a repair. In general the reliability of lcd televisions seem to be very good. Out of warranty repairs are more expensive because of the board level repair, some service manuals don&rsquo;t even come with a schematic any more, just a block diagram so you can determine which board is the culprit. In the latest generation of lcd tv&rsquo;s they have condensed the circuitry down in most cases to about 3 smaller boards. Unfortunately though when they do fail they seem to fail big, many of my repairs have involved replacing the panel. Back in the days of the component repair I never purchased an extended warranty because I could always buy the small part and fix it for a very low cost. But now...<div><a href="http://www.techlore.com/blog/entry/26724/What-to-expect-when-repairing-lcd-tv-s./">[Read more]</div> Televisions and Projectors Wed, 19 Aug 2009 19:21:43 GMT zapdbf http://www.techlore.com/blog/entry/26724/What-to-expect-when-repairing-lcd-tv-s./#discussion?src=blog_rss http://www.techlore.com/blog/entry/26724/What-to-expect-when-repairing-lcd-tv-s./?src=blog_rss http://www.techlore.com/blog/entry/21084/Why-does-a-fuse-blow-/?src=blog_rss <img align="right" hspace="10" src="http://www.techlore.com/imagelib/contentitem/21084/21084.jpg">First off we need to understand what a fuse is. A fuse is a safety device, primarily designed to protect something from fire or damage. A normal fuse is simply a small wire running from one electrode to another electrode and encapsulated in some kind of fire proof casing. A fuse should not be confused with a circuit breaker. A circuit breaker has the same purpose as a fuse, but it can be re-set and used again. A fuse has to be replaced when it blows. Fuses, especially ones found in a television, can be very deceiving and hard to find. They come in many shapes and sizes. Other components like; resistors, or coils, may also do double duty and act like a fuse. This behavior is engineered into the component. A fuse under normal conditions will allow the free flow of electricity to the circuit it is feeding. Normally, if everything is working correctly, the fuse has absolutely no effect on the circuit. If the circuit that the fuse is feeding draws too much current, the fuse wire will get very hot, very fast, causing the wire to disintegrate or burn open in one spot. Once that wire has...<div><a href="http://www.techlore.com/blog/entry/21084/Why-does-a-fuse-blow-/">[Read more]</div> Cameras and Camcorders Phones, Smartphones, and PDAs Portable Audio / Video Players Thu, 07 Feb 2008 20:58:33 GMT zapdbf http://www.techlore.com/blog/entry/21084/Why-does-a-fuse-blow-/#discussion?src=blog_rss http://www.techlore.com/blog/entry/21084/Why-does-a-fuse-blow-/?src=blog_rss http://www.techlore.com/blog/entry/19795/Sony-Recall--/?src=blog_rss <img align="right" hspace="10" src="http://www.techlore.com/imagelib/contentitem/19795/19795.jpg">From time to time people have been upset because they feel that their tv or electronic device made by sony should have been re-called. In truth Sony will issue in-warranty maitnance repairs or recalls that your device needs. If you registered your product, they will usaly send you a letter outlining the problem and the required repair. Not everyone will receive this letter. Sony has a place on their website where you can type in your model number, and it will tell you of any recalls or other important information about your Sony product. I suggust that you visit this site before your warranty runs out. To see if any updates have been issued for your sony products click below. http://esupport.sony.com/?ref=http%3A//www.sony.com/index.php<div><a href="http://www.techlore.com/blog/entry/19795/Sony-Recall--/">[Read more]</div> Cameras and Camcorders Portable Audio / Video Players Gaming Receivers and Audio Components Mon, 12 Nov 2007 16:01:55 GMT zapdbf http://www.techlore.com/blog/entry/19795/Sony-Recall--/#discussion?src=blog_rss http://www.techlore.com/blog/entry/19795/Sony-Recall--/?src=blog_rss http://www.techlore.com/blog/entry/19754/The-Pixel-Kunumdrum/?src=blog_rss <img align="right" hspace="10" src="http://www.techlore.com/imagelib/contentitem/19754/19754.jpg">All televisions have a small display unit of the screen called a pixel; a pixel is the smallest picture element on the screen. It will produce a number of colors with varying intensity, comprised of three primary colors red, green, and blue. Take a magnifying glass and get real close to your tv and you can see the three separate colors that form a pixel. On the older crt type of televisions an electron beam was scanned across a set of pixels to illuminate the pixel. The pixel was made up of a phosphor coating that illuminated each of the three pixel elements at different intensities generating the color for that spot. In all of the new modern displays each pixel is a separate electronic component, independent from the pixel next to it. Because each pixel is on its own, it is possible for just one of these pixels to become defective over time. It will do one of three things, it will stick on (always emitting light) or stick off (always black) or intermittently stick on or off. There is no way that a technician can remove the defective pixel and replace it with a good one.

Luckily Most Sony projection tv's no matter what model you have should be similar to my explanation below, Since Sony rarely fully re-engineers a tv what I am about to say will apply to most Sony projection TV's. A service manual is generally not needed to perform the repair. WARNING! If you don't have any electronic experience this is not for you, I assume no liability for any harm that may come to you or your tv. Perform this procedure totally at your own risk. High Voltages exist in your tv and on the boards I am going to talk about, and can have high voltages on them even after the tv is unplugged. What has happened to your tv: What has normally happened is that the convergence output driver ic's either one or both of them has shorted. Causing your picture to be un-converged, The Symptom of your failure can take on many different looks, so one explanation of what the failure looks like will not be adequate.
