Product Description

The SAMSUNG LN40A550 delivers the sharpest, most realistic picture quality you've ever seen. Full HD (1080p) contains 1.5 times more scanning lines than conventional HD TVs. That means more pixels, more details and a better picture. A resolution that is approximately twice as much as conventional HD TVs creates the most perfect picture imaginable. Contrast and brightness levels achieve new heights in this LCD TV. Watch movies and shows come to life with enhanced details in very dark or bright scenes. Enjoy a more realistic, sharper picture quality that's sure to catch your eye with 30,000:1 contrast ratio. One of the most important features for an LCD panel is the pixel response time. Response time refers to the amount of time it takes a pixel to "refresh" itself-to go from being active to being inactive, (ready to be re-activated). The lower the milliseconds, the faster the response time. A very fast 5ms response time virtually eliminates any blurring and gives you smooth-motion action scenes.

With our Wiselink USB connection, you can easily and quickly hook up your MP3 player or digital camera and entertain family and friends with a photo slideshow set to music.

Wide Color Enhancer/Cold Cathode Fluorescent Lamp

The NTSC (National Television Systems Committee) has established the color standards all TVs in America try to meet. And typical LCD TVs only meet about 72% of this standard. Samsung LCD HDTVs use Cold Cathode Fluorescent Lamp back lights to give you 92% coverage of the NTSC standard, ensuring truer, more breathlessly vivid colors.

Samsung’s exclusive Wide Color Enhancer technology delivers more brilliant colors, even in bright areas of the picture where blues and greens are washed out on conventional screens. The system displays wider color reproduction, showing you truer colors – the fresh green of spring foliage, the intense blue of the summer sky.

Audio Features

TruSurround is a patented SRS technology that solves the problem of playing 5.1 multichannel content over two speakers. TruSurround delivers a compelling, virtual surround sound experience through any two-speaker playback system, including internal television speakers and headphones. It is fully compatible with all multichannel formats up to 5.1 channels. High-quality virtual surround sound can be experienced with just the two hidden, downward-firing side-mounted 2.2-channel dome speakers built into the TV.

SRS TruSurround XT technology delivers an amazing, simulated 3D effect with clear dialog and powerful bass.

TruSurround XT audio also adds three audio enhancement technologies to produce an amazingly immersive sound experience.
  • Dialog Clarity brings movie dialog into Focus during the playback of any surround-encoded material to make speech much clearer and crisper.
  • TruBass creates incredible deep rich bass allowing a person to perceive significantly deeper, richer low bass tones that are far beyond the physical low frequency capabilities of the speaker itself.
  • The SRS WOW feature widens the sound stage by processing standard two-channel stereo material as well as multi-channel encoded material for a dramatic improvement in the playback of any stereo audio over a two-speaker system.
Stereo broadcast reception is offered for MTS and SAP with 181-channel capacity. A sound leveler keeps audio volume consistent during channel changing.

Which Size HDTV is Right for My Room?

HDTV Size chart
With standard-definition TVs, the rule used to be that viewers would feel comfortable watching a set from a distance of 3 to 6 times the screen size in inches. With HDTV, the resolution is so much better that you can sit closer to a larger TV without noticing the pixels. So with HDTVs, the rule tends to be you can sit anywhere from 1.5 to 3 times the screen size (in inches) for the best experience.
If you know the size of the room you have already, where you want to sit, and where your new HDTV should go once you get it, you can figure out the size HDTV you should get.
  • Minimum size = Viewing distance/3
  • Maximum size=Viewing distance/1.5
  • Full HD 1080p Resolution
  • Wide Color Enhancer
  • 3 HDMI Inputs
  • USB 2.0 Connectivity
  • HDMI-CDC Compatible

Customer Reviews:

  • Excellent Price - Good TV
    I ordered on a Friday morning, recieved the TV via Pilot Air frieght on the following Tuesday. Delivery was no-hassle and on time. TV looks good out of box after i did some tweaking (thanks AVS Forums!). I got this deal when Amazon briefly lowered the price so it was a hell of a deal.

    I did a lot of research before buying a TV, and this one had great reviews on Cnet and various other sites. One thing i found out later was that Samsung sends these reviewers panels that are made in the Samsung factory called "S" panels. These are usually far superior to the panels that Samsung outsources to third parties, "C" and "A" panels. Sadly I got a "C" panel, and it definaltey doesnt have the clarity of the "S" panel on display at Costco. While I got a great deal on this TV, and the picture is still good and I'm happy with the purchase, I'll probably not buy another Samsung TV because of this issue. Its basically a crapshoot on what kind of panel you'll get, and no way to tell until you take the TV out of the box.

    If you're on the fence about the LN40a550 vs. TV X i would go to Youtube and search "S" panel vs "C" panel and look at the demo that was created and you get the idea. ...more info
  • Great TV... but do not order from ""ELECTRONICS EXPO" from NJ
    Excellent TV. But watch who you are ordering from. I have a problem with the TV that came damage during shipment. I have called several time to resolve the issue with exchanging it. They told me to contact the "Manufacturer" to fix the problem. So, I called Samsung and they had a tech to see the problem. When the tech saw the TV, he told me that Samsung with not replace the LCD screen. He told me, it would "COST" me $900 to replace it. I call the Electronics Expo again, and now they tell me that they have to contact the shipper. I waited and waited with no responds. I was so angry, I disputed with my credit card and gave them a bad feedback. I also had a similar problem with VANN'S but there are GREAT. I love them. Watch out for "ELECTRONICS EXPO"....more info
  • Broken TV took 3 weeks to fix
    Samsung sent me a tv that worked for the first 3 days and then broke all on its own. When I asked for the repair, it took 3 weeks before they could repair it because they have to try different parts and then order the next part and reschedule after each time they try. All in all it's fixed now, but when I called customer service to let them know how ridiculous it was the lady was rude and trying to brush me off. I most likely will not be purchasing a samsung tv next time....more info
  • Excellent Low Budget LCD
    Been looking for a LCD 40-46" for almost a year...waiting for a great deal on a LNXXA650 or higher model. Came across this LN40A550 when comparing screens and options at a local retailer and decided that I would be willing to save some $$ to replace our old standard TV.
    Delivery was great. They helped unbox and gave a few pointers as well. Waited a few hours and powered it up. What a great picture!! The size was perfect for our room. Just simple plug and play setup. Definitely would recommend this to others looking for a low cost LCD with lots of features....more info
  • Very nice HDTV for a great price!
    I researched all over and was set on a 40" v- series Sony. Went to a store to see it in person and this Samsung 40" 550 was $400 cheaper and stole the show. Then looked online and found a great deal here. My only gripe was the shipping took about a week longer than promised. But this deal and TV is worth the wait....more info
  • Great TV at a great price!
    Just before Christmas, our 6 year old Panasonic projection was dying a horrible death, so the hubby and I decided to start looking for its replacement. We had been to several electronics stores, checking online, comparing pictures and prices of many sets. We decided on a Samsung 40 inch, but the prices were out of our range. We kept looking and kept waiting. Finally, I found this model at a price we could afford and jumped on it ([...]).

    Once it arrived (love the free shipping through Pilot!) I was able to hook it up within a matter of minutes while hubby was at work, and my son and I were watching television. WOW! The colors are bright and no matter where you sit in my living room, you can see the screen clearly, unlike our old projection. I agree with other reviewers about the sound quality being lackluster, so we will be purchasing a surround sound system in the near future.

    Overall, I highly recommend the Samsung brand and, in particular, this television to anyone looking to purchase an LCD HDTV. I am so glad we purchased this great TV, and we are planning on enjoying it for a long time! ...more info
  • Samsung LN40A550
    The product is more than I ever expected. I'm using it in a second home and only have a small Digital/HD antenna. The picture quality is exceptional. Can't wait to have satellite input to expand it's capabilities. The HD by airwave is unbelievable. No doubt the best TV I've ever owned....more info
  • Turns on and Off by itself
    I bought this TV a little more than month ago from Bestbuy. I was very impress with the picture quality, my eyes were glued to the screen, the clarity and color was amazing after I change around the picture setting. until a few weeks ago the TV turned off by it self and it turned on again after about 2 seconds. I thought I did something wrong with my set up. I went over the set up all over again according to the manual, but it is still happening.

    Until one night it happened twice about 30 minutes apart, and I decided to exchange it with the same exact model. However, after about 2 weeks it happened again!!!! Twice in a row two different TVs??? are you kidding me?? I thought Samsung TV suppose to be one of the best??? I took it back and bought Samsung LN40B530 instead, a lower model but newer. So far, it works just fine, and picture quality is just as amazing. Don't buy this TV, save your time and money for other model!!...more info
  • great TV, a must-buy
    I have own this tv for 4 months now and i can say that it is my best buy on amazon ever. i haven't had any single problem with it yet and love everything about it!
    I would like to say something about the price since it seems like our review are based on a product performance and the amount of money we spend to get that performance. Had i spent $200 more on this TV, maybe i would have expected a lot more from it : maybe for a better sound for example but for the price i bought it ($850 or a little less) i think i feel comfortable able investing in a home theater to get the most out of the HD experience!...more info
  • PIP feature
    I ordered the product hoping the PIP feature would be the same as what I'm used to but it is not. It's useless for the application I'd hoped for. I'm still trying to figure out if I can use it at all. ...more info
  • I can get some Satisfaction
    I've been looking at HD TV's for a year. I was weary of discussing pros and cons with sales people who seemed weary of their jobs and provided little info. Luckily, my daughter's significant other took the time to sit with me and go over the pros and cons of various TVs and which bells and whistles did I need and which were overkill. Then he told me what a great experience he had buying from Amazon. So I tried it and I was thoroughly impressed. My 40" Samsung Samsung LN40A550 40-Inch 1080p LCD HDTVis terrific, delivery was quick and efficient, and there was no shipping charge! Now, if we could just get our government to run as effeciently as Amazon......more info
  • Totally satisfied: great T-V, great price, great service
    After months of indecision, Amazon's great price and free shipping got me off the dime on this and I'm so glad. I have HDTV service from my Time-Warner and made connection with HDMI, and am absolutely delighted with the picture. The sound is very good from the t-v, much better than average, and more than adequate for news, talk, etc., but for other content I crank up my home theatre.

    Performance out of the box was very good. As I tweak a little here and there, we've moved up to excellent. Absolutely spectacular picture on HD source, and much better on SD than I had expected.

    Amazon's free shipping provided a lot more service than I had anticipated. I expected the box to be dropped in my co-op's receiving room and that I'd have to do the rest. Instead, these guys made a delivery appointment, brought it up to my apartment, unpacked it, and got it going. They were polite and efficient. A lot more than I expected for free shipping. A major bricks-and-mortar retail chain wanted $300 more for the same t-v and $100 more to deliver it. Way to go Amazon.

    This is my first big-ticket purchase from Amazon and I can assure you they have won me over. Amazon is not just for buying books any more....more info
