initially i wanted to buy a lcd tv, but i have heard that led tvs are better, is it right ? which one is better? what are their cons and pros?
Answer
LED is a type of LCD. They are the exact same type of TV. The only difference is that "most" LCDs use CCFL backlights as their light source (florescent lights). LED LCDs use LED backlights as their light source. That is the only difference between the two options.
LED backlights provide LCD televisions with more vivid colors, truer blacks, and deeper contrast. But it is considered a premium feature, and therefore you are expected to pay extra for it (quite a bit extra). In the 40" - 46" range, I think there are going to be visible advantages to it, but not necessarily a return on the dollar. If you break 50", then okay, you are likely more warranted to consider the LED option.
Most, if not all, LED sets also automatically come with 120Hz or 240Hz refresh rates. This helps with LCD's inherent flaws in motion playback (all LCDs, any light source type, suffer from motion blur or ghost trails). But again this is considered a premium feature that you are expected to pay extra for. So this further drives up the price of an LCD set. And again, depending on what size of TV you're getting into, this may or may not provide a reasonable return on the dollar.
Just so you know, Plasma has superior colors, truer blacks, and deeper contrast than LED LCD. And it does so right out of the box. There is no special feature to pay for. Plasma is also near instantaneous in response time so flawless in motion playback (like a CRT/tube). Again, that is inherent to the technology, you're not paying extra for it. So you actually get a superior image for less money by going Plasma. Something worth considering.
And don't fall prey to all the myths and lies about modern Plamsas. They no longer suffer burn-in. The good brands do not have shorter life spans (their sets are rated to like 100,000 hours which is equal to if not far beyond LCD sets). They are not power hogs, you can buy energy star certified Plasma sets now.

What's the best flat panel tv today LCD, LED, plasma?
Youk
I want a 50". Also to get cable service into another room without running cable I need the wireless, does it work with current cable box? Is the picture good?
Answer
LED is just a form of LCD.
In 40" and above Plasma wins out in image quality (motion playback, color, blacks, and contrast). LCDs can provide a bit greater brightness, but optimized TVs don't run super bright (it washes things out).
Not sure what you mean by wireless cable service. Are you talking Slingbox? Are you talking a wireless HDMI box? Wireless anything is what it is. It can be good, but its likely not going to be quite as strong as a wired solution.
LCD
( http://en.wikipedia.org/wiki/Liquid_crystal_display_television )
LCDs inherently suffer problems with motion playback. They suffer from motion blur (ghost trails). This is compensated for with the 120Hz/240Hz refresh rates. This feature helps out a lot, but is not 100%. And you are expected to pay a price premium for this add-on.
CCFL LCDs have muted colors, grey blacks, and so-so contrast. This is compensated for with the modern LED LCD. The LED backlight provides a massive jump in quality in regard to those 3 things. It brings it to a near Plasma/CRT/DLP level.
But in smaller sets, LCDs are the go to choice. So for the time being they will certainly still fill an important need there. And there also offer a certain sense of familiarity for many, as LCD computer monitors have been the norm for so long now.
Plasma
( http://en.wikipedia.org/wiki/Plasma_display )
Plasmas are inherently near instantaneous in their refresh rate. They are flawless in motion playback. While you might see some tagged with 480Hz or 600Hz sub-field motion drives, this is not a refresh rate. Its more so marketing to trick consumers (because of LCD's refresh rates). But in reality the technology just works quite differently (its more like your old CRT/tube set).
Plasmas inherently deliver vivid color, true blacks, and deep contrast. They do this right out of the box. They are a better overall image. And so you get a better image and perfect motion playback without having to pay anything extra.
Plasmas were not always this good a choice though, they have improved greatly over the years. But because of those past problems they do currently suffer from many myths and misconceptions. The main ones being that they suffer from burn-in, they are more expensive, they have shorter life spans, and they are energy hogs.
Modern Plasmas do not suffer from burn-in. After they are conditioned, you would have to actually work hard to accomplish a burn-in. To condition a new set all you need to do is keep the brightness and contrast turned way down for the first 100-200 hours of use. After that optimize and enjoy.
Plasmas are not more expensive than LCD rivals anymore. Any especially with LCDs needing high end features like 120Hz and LED backlights to compete. Those features often make LCD far more expensive to buy.
Plasmas do not have shorter life spans. The reputable brands will deliver models that are rated to 60,000 - 100,000 hours. That basically means that in 10 years time, at 8 hours a day, 365 days a year, you would only really see at most about a 10% loss in brightness. So the set is likely well useable for beyond 10 years.
Current Plasma models are now energy star certified. This means no more being power hogs against LCDs. They can match LCDs in this regard. But every model is different. There are some LCDs that still perform better, and there are some LCDs that perform much worse. It changes ever year as new models come out.
