Excellent value
The picture quality and clarity is just super. The overall appearance of the unit is very good quality. The White glove service was just excellent. I would buy again if I had another purchase of this type.

Power Supplies went bad
I bought this TV around February of 2009. I have never ordered a major appliance before on the web. When it arrived it was well packed, and though a little troublesome to get in the house it was OK. Every thing went very well and hooked up easily. When I turned on the unit it was Beautiful. The pictures is sharp and clean, The blue ray video is the best I have ever owned. The sound from the tv speakers is OK, not horrible not spectacular, average to maybe a little under. You can watch movies and shows and not be bothered by it but your definitely going to want to have an external receiver system for that theater feel when watching movies.
The reason I gave this set a 3 was, after 7 months it started taking longer and longer to turn on. The leds on the front would blink, the set would try to come on then wouldn't. The 3 leds on the front would sequence back to the beginning and then the set would come on. This went on for about 2 weeks until one day they would just cycle with no picture ever appearing. I called Samsung and they gave me an rma number and a local shop called me and set up an appointment. They came out 4 days later and replaced both the Primary and Secondary power supplies. Repair took around an hour but now the set works great again. A couple of things....I was very disappointed this set had a catastrophic failure in under a year and live in fear now that this is a design problem with the set and it will have to be done over and over again. 2nd thing is the repair tech took one look at the set and knew exactly what was wrong with it, even brought the parts in before looking at it. This could have been because I described the problem so well I troubleshot it for him or it could be that whenever this model breaks that's the problem indicating a design flaw. Any way, The set has been working great ever since the repair and I am very happy with the picture. If you buy one and don't have any problems with the electronics, You will be very happy with your purchase.

Best TV Yet!
Bought it when Circuit City was closing. Paid 00 out the door. Knock wood, has been a great TV since day one. Many options, firmware updateable, strong picture, HDMI inputs, great for blueray movies. We don't go to the theatre any more! Only issue is speaker placement as it has to be turned up to hear when using internal speakers - I think this was designed with home theatre in mind. What's great about this TV (besides the outstanding picture) is it is has an LED driver - so there are no bulbs to replace!! Great value!

Best value for the size!
I did a lot of research before purchasing. Size was my main concern. Could not see spending 4K on a plasma TV. Did not want the hassle of a DLP. LED seemed the best choice for me. When I saw this set at Best Buy I could not believe the picture! This thing is huge! Super crisp and bright! I purchased online with extended warranty (just in case) Paid around 00. Which included free delivery. Factory speakers are lame, but considering the price I am super satisfied!!! Did I forget to mention the picture is freaking huge! Now I am waiting for the Samsung 73" to be offered in LED. Thanks again Samsung for a great product!!!!

Excellent DLP HDTV that beats both Plasma and LCD
This is my second Samsung DLP HDTV. I bought it in February, 2009 and still own it. The colors and resolution are better than the previous DLP that I owned (the earlier on was based on a color wheel, which after 5 years had to be replaced) - this one is LED based which (in theory) should last longer. I also own a Panasonic Plasma (50") and have compared it with the Plasma side-by-side. The Plasma TV has more enhanced colors whereas the Samsung has more natural colors.
I usually watch sports or movies and have not seen any video lag - the close-up resolution is excellent. I do not use the speakers that are on the TV but have connected the TV to a Yamaha surround sound receiver using HDMI and audio cables - also have a Blu-Ray DVD player connected and even when I play regular DVDs they seem to be very sharp. I'm not sure if that is because of the Blu-Ray player or because of the TV.
What I like about the TV in addition to the above is that is light enough to be moved by one person. The delivery person was very good - he and his helper unpacked and placed the TV where I wanted it and did a basic test to see that everything was working.
When watching movies, either DVD based or from cable - the HD rendering is excellent - very sharp, blacks are blacks and with very natural colors.
All in all, I would strongly recommended this TV brand - my first Samsung DLP worked flawlessly for 5 years before I sold it and this one has worked flawlessly since I bought it in Feb of this year - the build quality rivals that of the other prestigious Japanese brands with a price that is a fraction of what you will pay for similar plasma or LCD TVs.
