Summary: Replaced my older Samsung LCD TV (LN52A650) with this one (PN64E550). In general, this TV has much more vibrant colors and a noticeably better response time (I.E., plasmas have a much better refresh rate - you don't need to turn on any of that 120Hz/240Hz motion stuff that LCD/LEDs use which looks terrible; no "soap opera effect"). The downsides is that the glass is very reflective which makes daytime viewing troublesome and the buzzing is noticeable at times.
Summary: I purchased this tv for my newly finished basement family room. After receiving the product and hooking it up, I was initially disappointed with the picture quality. It took a little bit of time playing with the picture settings, but once I got it right the images jumped off the screen...and I'm not even talking about the 3D mode! As with most thin televisions, the sound leaves you somewhat unsatisfied.
Summary: great TV. First one came with holes, so they took it right back. 2nd one was perfect. Only problem I had was with Amazon. There was a promotion that said if you bought by Discover Card, you'd get another year warranty, but Amazon says it's not their promotion and it's Discovers problem......same from the other company(discover). Be careful what you sign up for.
Summary: So i picked up this tv and so far so good, it isn't buzzing too badly compared to what most people say and it is already starting to soften as the tv gets broken in. My biggest complaint is that the HDMI arc sends a signal which changes the amplifier input. no on basic systems that might be ok, but on my DENON avr 3313 it is quite annoying. There is no way to turn it off o i have to use optical. most amps only have a few of those and mine are all used up.
Summary: I am not a huge fan of Plasmas, b/c they always seem to dark to me. That being said the picture quality is terrific and the smart tv interface is great. The TV i received does buzz a bit, which is annoying. The remote control is slow to respond for some reason, but I use my android smartphone to control the television anyway. It does not give off a lot of heat or use much power for being so huge. The TV screen does have a bit of glare in a bright room.
