I have a question about LCD tv's?

I've been reading customer reviews about LCD tv's online and some people mention that they find a dead pixel right out of the box on some of them. What exactly is a dead pixel, and should I specifically avoid those brands that have that problem? I noticed that more than one brand/model of tv is said to have this problem. What causes it? Also, what is the difference between HDTV and EDTV?

you should get an lsd tv instead. They're really cool. First you go to the store, buy an old broken black and white tv. Then get the LSD components. Then watch the colors come alive!
On LCD screens, the picture is made up of little tiny dots - they are so tiny that your eye tends to blend them together and you see a nice picture, not a bunch of tiny dots. But - if you look close, or use a magnifying class, you can see the individual little dots that make up the picture. These dots are called "pixels". When you have a "dead pixel" it means that one of these tiny dot areas is not working. As tiny as they are, a dead pixel can be noticeable if the right picture is shown on the screen. As with anything, you get what you pay for. More $$$ usually equals better quality and higher reliability.
I'm sure that it is possible to get an LCD TV out of the box with a dead pixel, but it is fairly rare. I've been dealing with LCD technology since before it was available to consumers, going back to the Barco light cannons in the early '90's. As long as it's a recognizable name brand and not something from eBay or unknown brand only available from the Internet, your worries are minimal. As for the distinction between HDTV and EDTV, HD has always been specified as 1080i, but consumer LCD technology was limited to 720p. But it could still accept HD inputs, so it was called HDTV. As manufacturers finally able to make true 1080 sets, they were the true HDTV sets, and the 720p became called EDTV sets (Enhanced or Extended Definition). All of them can accept HDTV, but only the 1080 sets can display true HDTV.
