Summary: I've had all Sony tvs in the past but since Samsung had been getting such great reviews I figured I would give it a try. The picture is great as long as the brightness is low. If it is high then you get shadowing. The bigger issue was just after the 1 year warranty ended the the screen died. The process to get it fixed was a nightmare. I was referred to 4 different repair facilities by Samsung's support.
Summary: this TV is amazing. The internet connection adds lots of other options without buying additional hardware. Sound is of excellent quality and unexpected volume range and different sound modes. I have had it for a year now and it has never missed a beat. the color and the resolution is clear as you could expect. I recommend this model to anyone. And the best part is how easily I was able to order, receive and install the unit right out of the box.
Summary: I would highly recommend this TV or any of the 240 Hz or 240 CMR LEDs from Samsung, particularly in 3D. These TVs blow away most other brands, and if you don't believe me, go to the local electronics stores with the walls of TVs and compare for yourself.
Pros: Although I own the 55" version of this TV, I had to add a review here since someone had to say Samsung TVs are poor quality. One, do they even make DLP TVs anymore?
Cons: You will be disappointed in trying to watch standard definition on this TV because it emphisizes the graininess. Be prepared to have high def programming and a 3D blu ray player or PS3. Also, the 3D glasses for this model year are not very comfortable for wearing long periods of time.
Summary: It was good since we purchased 1.5 yrs ago. but suddenly it became intermittent black screen for about 1.5 hrs. There is no way to predict when it is. Also after screen went to black, I used another TV (Not Samsung) to check the signals and everything was good. Samsung is not good name to hold quality. Buyer must be aware of it and I would not buy Samsung stuff if they can not keep TV set for 1.5 yrs. Also wifi could not turn off if you enable it.
Cons: I have a 67" Samsung DLP TV that cost $2500. After warranty expired ( a very short 1 year) the TV developed white spots due to the failure of the DLP chip. Despite an overwhelming number of customers with the same problem Samsung refuses to address the problem even though they did a secret recall on the 61" version of this TV. Do an internet search on white dot problem.
Summary: If you're not a gamer, this TV is excellent. It's got one of the most gorgeous displays of any TV currently on the market. If you ARE a gamer, avoid this TV like the plague. I'm big into first-person shooters and I couldn't adjust the TV settings to reduce the input lag enough to make my games playable. I did a lot of research and ended up getting a Panasonic plasma.
