Samsung UN46B6000 46-Inch 1080p 120 Hz LED HDTV Review

I purchased this TV and ended up returning it a week later. The physical TV is gorgeous, but unfortunately it has issues with the screen that I couldn't live with.
During normal viewing (in the store, in a lit room during the day), the picture quality is awesome - it has inky blacks and vibrant colors. The problem has to do with its "screen uniformity", something I didn't even know was a "feature" to consider when I was researching TVs.
This TV has an "edge-lit LED screen", which means the LED lights are along the edges of the screen shining inwards toward the center. Unfortunately, this makes for very uneven lighting across the screen. It's not noticeable during the day, but at night in a dark room watching a dark scene, there were a number of faint glowing streaks coming from the edges of the screen. It was very apparent in the letterboxing (the black bands over and below a widescreen image), in which there were feint cones of light coming from the corners of the screen.
I researched the issue (I searched for the TV's model number and the words "screen uniformity") and it turns out this is an issue all the LEDs have. The review sites offer the technical explanations for it.
I'm by no means a A/V snob, but the problem was almost instantly noticed by me and everyone I had look at the TV.
I returned the TV and instead purchased the Samsung LN46B650 Samsung LN46B650 46-Inch 1080p 120Hz LCD HDTV with Red Touch of Color. It costs almost $600 less, has just as gorgeous of a picture (I don't notice the contrast ratio difference), and has none of the screen uniformity issues.
I'll say that again - the NON-LED 46'' Samsung TV has a BETTER quality picture and costs hundreds of dollars less. Unless you are using this TV in a lit room during the day and you value only the aesthetics of such a thin TV, go with the regular LCD. You won't be disappointed.

LG 47LG90 47-Inch LED Backlit 1080p 120 Hz HDTV, Gloss Piano Black with Blue Review

I owned it for a few weeks and then returned it. For this much money for a 47" LCD, I expect a lot.
The colors were saturated and the blacks were dark, just as you'd expect from the LED backlit set.
But the blooming or haloing created by the local dimming is just too much. There aren't enough LEDs in the array. So when white text scrolls on a black background like credits you can see a halo around ever letter or word. Then as they scroll, the LEDs turn on and off accordingly and you can very easily see this "pop" of the LEDS turning off. You then begin to notice the same haloing around faces in dark scenes. Pretty soon it is all you see.
You can turn local dimming off, which essentially turns the LEDs into an always on backlight like all CCFL based LCDs. But then you lose the dark blacks benefits, and soon you realize you paid 50% more for a feature that you aren't using anymore and now your set looks about the same as all the others at far less cost.

I was a committed DLP fan before undergoing a conversion experience on Friday April 17th. I had planned to replace my Samsung DLP with a Mitbushi DLP or LaserVue. In the final hours, I just couldn't go through with it.
A major Los Angeles vendor set up a display with the UN55B7000 sandwiched between a LaserVue and a Kuro 151. The results were pretty plain to my eyes. The Luxia pretty well crushed both of them. The cult of Kuro will denounce me for heresy and blaspheme, but this is what I saw. About 1 hour of fiddling with the settings on LaserVue did not change the situation much. The Kuro was locked in at calibrated settings which the employees would not allow me to change. Evidently, it was fully tuned up. Once again, this left me with the impression that a fully calibrated Kuro is an over-rated beast indeed. No wonder Pioneer quit the market.
The bottom line: I bought this unit the next day. It took about 2 hours to tune up after I took it out of the box. [Use the natural color setting. Customize motion smoothing to 7 for jitter control and 7 for blur control, or shut it off entirely] Since then it has been pretty astounding. Unbelievable color. Unbelievable reds. Unbelievable contrast ratios. Unbelievable black levels. Very bright. Generates no perceivable heat. Does not get hot. The detail and sharpness and depth of image is truly astounding. I have never seen anything that can compare, and I have been shopping for several months now.
Cons
I am still questioning the merit of the 120Hz motion smoothing technology. It does weird things to slow motion instant replays. It does stranger things to 24fps movies. Seems to work best with live actions sports and HDTV programs shot on digital. You can always turn it off. Blu-rays seem more natural with the technology switched off. Ultimately, Blu-Ray looks magnificent either way.
Advice
A word of advice for the first reviewer and everybody else. You should never, never, never use the speakers on your HDTV. All HDTVs are equipped with pathetic 10 watt reference speakers that stink. All HDTV owners should invest in some sort of home theater surround sound system. It doesn't have to be that expensive. Even a $300 Home Theater in a Box will make a world of difference.

My family and I just love this TV, particularly for watching sports. We looked at a lot of LCD and Plasmas but saw none that gave us the sense of depth this one does. It is like 3D. Moreover, our family room is also a sun room during the day but the picture is just as strong in the day time as it is when the room is dark. The viewing angle is comparatively wide. We see no appreciable drop off when it is viewed at an angle. It is large enough that my wife can view it from the adjacent kitchen with ease.
Learning how to use its features and to set it up is another matter and that is the one gripe I have with the TV. Samsung only provides a four page manual which tells the owner nothing. Instead it includes a flash drive which contains a manual for its use but it took me over three weeks to realize what the flash drive was for. The manual does not show the available ports or how things are to be connected to the TV. I finally figured it out by trial and error and got the flash drive connected. Finding out how to use it however, was again a lot of trial and error. Once I was able to read the pages, it was hard to read, mostly grey on black (I hate black-you can't see where anything is on black). Figuring how to page the manual on the TV isn't easy. Samsung provides numerous steps to take but the user has to leave the Manual screen to go through the steps and unless the user writes out all the steps, it is a tiresome process to follow the steps.
So I tried using the flash drive on my computer. Well the manual is in a strange format so it will not open normally. Windows searched for a driver that would allow viewing the manual and found one which I downloaded and installed The one I found that worked was from IrFanView but one must also download all the plugins before it will work. However, when I opened the Manual, it was unprintable except with a screen capture utility.
That was more trouble than it was worth and it then dawned on me to go to the Samsung Support Center and see if there was a Manual that could be downloaded. Voila, the Manual was available in both PDF and Word formats but because the Manual is in three languages, it is 273 pages long. Just print the first 75 pages.
What I found is that with no difficulty I could run picture shows directly from either my camera or from a card reader. They come out beautifully. If I tried to print pictures that big, they would be grainy as all get out. But the pictures show in full size on the big screen in terrific detail and color and they have depth.
But I wish the USB ports were either on the side or the front where they are easily accessible. I intend to wall mount the screen but if I do I won't be able to get to the connections which are on the back. And even then it is difficult to insert USB cords because the recess is so narrow.
We love this TV however, because of the lack of a printed manual and the location of the USB ports, I can only give it 4 stars.

Had my Samsung UN55B8000 TV a couple of weeks now. It has more than lived up to the hype. Hooked it up and put on a blu-ray disk. Even the delivery guy's jaw dropped, and he's delivered/set up hundreds of TVs.
TV is only inch and half thick and only weighs 60 pounds or so.
In fact, it is sometimes almost too good. When viewing people on HD you can see every little mole, scar, wrinkle, stray hair, makeup, five o'clock shadow, makeup line, etc. I'm sitting here watching the news and I can clearly see tiny pieces of lint on the guy's black suit. I'm guessing the talking heads of tomorrow are all going to have to have much better complexions.
If you like to tweak your TV this one provides a lot of different controls. There are already some websites that will give you what they consider good tweaks to maximize the pic. You can also look for the B7000 tweaks. Looks pretty darn fantastic right out of the box so if you aren't a techie, don't worry about it.
Sounds..not particularly good or bad, but I don't want TV speakers taking up space anyway. If you are going to spend this kind of money for a TV you should be using your stereo system.
Some reviewers were complaining about the number of inputs. Again, how many is enough. I run my PS3, XBOX360, IPOD, and the Dish box through my Denon and so I only use one HDMI.
You can plug it into the internet. No set-up, just plug it in. First thing it did was download 12 updates to itself. Have no idea what they did but ...didn't cause any problems. It automatically loads up some of Yahoo's widgets. Fun to try but...not something I have really gone back and used much. Also has some built in content...recipes, artwork, etc. that I haven't bothered to look at.
You can plug in USB drives and view content directly off the drive.
I long ago got rid of my roof antenna. I bought a little Turk indoor antenna and plugged that in so I can pop over into over-the-air signals and watch TV. It will automatically search and find the on-air channels. It even downloads some kind of TV guide from the internet for the channels it finds.
I also wanted to see if there was any signal degradation from Dish. I haven't noticed the HD degradation with Dish that I had with Comcast. The way Comcast packed the HD signals you could see a real difference between OTA and the packed pics.
Samsung also provides software which allows you to use your PC as a server. Then you can display your pics, music, etc on the TV. Took a little playing around but was easy compared to some of the others I've tried to use.
I've played games with both my PS3 and the XBOX360. No problems. No pixelating. Did not bother to change TV over to game mode. I haven't fooled around with the 240Hz function. I just leave it on standard.
I'm sure there are other features I haven't tried. With the ability to update itself over the internet I have no doubt they will teach it even more amazing tricks.
I've set up my Harmony 880 Pro to control all my devices including the IPOD. IPOD menu/info will display (through my Denon) on the TV.
All of the above features are great but the main thing is... the picture is just absolutely mind-blowing wonderful.
So, fantastic TV. I am VERY happy with it. Obviously I highly recommend it.
((Now I'm watching Wall-E in HD and it is pretty amazing.))

I selected this specific television because of the integrated Netflix player. Set up took literally minutes and everything worked great until I tried to activate the built in Netflix player. I was not able to get an activation code from netflix because, although the tv could hit my home network and the internet, the player was unable to log into the Netflix activation server. I first called Netflix and was transfered to LG customer support, who were more interested in getting my phone number than working through the issue. We fumbled through a couple of things becore they informed me that they would need to send out a service tech and I would have to be available for 4 hours on a Tuesday for them to show up. Not finding this acceptable, I reached out to Netflix again. This time I got someone on the level 2 helpdesk who worked with me for about an hour on network things. Basically we determined that there was nothing wrong with my network, but that the problem resided in the television. He was willing to sit on the phone another hour with me while we brought up the LG tech on what had been done. After he walked through several remedial steps that didn't really have anything to do with the situation, the LG tech gave up and tried to schedule another on site visit. I insisted on talking to a supervisor who informed me that there was no Level 2 help desk for LG. After I pressed hard enough, she put me on hold and called someone she knew in Advanced techncal support (aparently an internal departmement). I got a promise for some to call me back. Everyone I had talked to was extremely friendly and told me over and over they wanted to help, but their depth of knowledge on this product was very weak.
After spending an hour with the advanced technical guys, they finally conceeded that they had never actaully set up a Netflix connection, but had seen one working. They also told me that there are known issues with Belkin routers (of course, that is the router I use.) I now have no less than 6 hours invested in getting Netflix to work on this tv and it still doesn't. I will now have to wait for a field tech to come out, do exactly the same things I've done over the last 6 hours and then inform me that I'll need a new board or something, but it'll have to be ordered. I should note that the other web applications integrated into the television work great, it's a shame I didn't buy the TV for them.
I already have a Roku Netflix player (it's even wireless) and I get great results on my Toshiba plasma TV. I should have just bought the tv I really wanted and went with a second Roku device for the new television.
UPDATE - After working with an authorized repair company, the main mother board was replaced and all issues with NETFLIX connectivity were resolved. I am still using the Belkin router and it works like a charm. There were some issues also with the speakers (they crackled at certain frequencies) but once they were replaced, everything seems to be working well.
