Summary: Awful software. For a long time Samsung didn't support Amazon Instant Video at all; now they claim to, but it suddenly stopped working on this one. I tried all kinds of "updates" at multiple levels, no help. The interface is pretty bad as well -- they have a "Web Browser", but even with a USB keyboard attached it's barely usable -- you still have to use the remote to move the mouse around and click in each field -- you can't, for example, tab to the next field even when...
Summary: This TV is everything! It is such a great television and is priced competitively! Everyone gives me compliments on the picture quality and I was blown away by the content it had in the smarthub and the 3D looks amazing!
Summary: My PN516500 Samsung quit working just after 1 year. The Web shows a class action suit for faulty capacitors over a number of years. Since my particular model was not on their list of models, the customer service rep said I am on my own. So, faulty capacitors, the bad power supply or whatever is wrong with mine, I would stay far away from Samsung. $1200 and it will not last 2 years. Your better off at rent a center.
Summary: The picture is 5+ stars but I would give the Samsung "smart" interface and features a 1 star. As typical with plasma screens, this one is subject to glare in a bright room or if you do not position your room lighting appropriately. I had to add curtains to a couple of windows for daytime viewing. The, so called, Smart Hub has access for Hulu+ (pay videos) but not Hulu (free videos). Also the browser does not allow you to access hulu.com.
Summary: I've owned this television for just under a year now and have had to have it serviced twice for internal component failures - the most recent just a few days before the warranty expires. I'd pair it with a Roku or Apple TV rather than relying on the built in smart features. Pros - Its got a great picture and is easy to use as a television Samsung service was quick and friendly both times Cons - SmartTV features are slow, clunky to navigate and frequently lose track of...
Summary: Internet functionality and video are excellent. The built-in audio is poor. The speakers cannot handle any amount of bass very well. In fact, low mid-range to bass causes the speakers to break up sufficiently to make me think that I had a pair of blown speakers. The sound quality, in the presence of a fair amount of bass, is horrendous. I will have to route the sound through my stereo system when watching movies. The sound from the digital output is fine.
Summary: Overall, I am satisfied with this TV. It is all digital which renders my present DVD and amplifier obsolete for operating with this TV. NO analog outputs/inputs are provided. The sound needs an auxiliary system but I expected that situation. I do not have 3D capability yet, so I reserve judgememt on that feature. I would recommend the TV to other perspective buyers.
