Summary: If your spending over $1500, get a 5-year WARRANTY. Bought my Samsung PN63C8000 on August 2010 for $3800. It was the best Top-of-The-Line Plasma TV. Beautiful Plasma. Then this April 2014, No Picture. No Audio. GONE. BOOM. After $215 on a Technician, I was told that I would have to replace the Panel for around $2000 and then what.
Summary: There is a purple band in the middle of my screen! You notice it in particular when you are watching a scene with a white background. A $4000 TV that lasted only 3 years and 2 months! My extend warranty just ran out at the end of the 3rd year. I just spoke to 4 people at customer support: a) they won't acknowledge that it is a common problem b) they informed me that I have to pay for all the repairs.
Summary: Google "Samsung purple band" or "Samsung purple haze" and stay away from this TV. You will be lucky to get 3 years of out if. Samsung puts components in there to just get it past the warranty, then you are on your own. I had a 2 year extended warranty and the purple haze came just after that. I wish Pioneer still made TVs....
Summary: Purchased this Samsung model back in 2011 and regret it. After owning it for only 2 years, the screen has developed a "purple haze" that shows up on bright colored/white screens. Doesn't matter what input you use; video games, Blu-ray, cable, etc. Samsung refuses to fix the issue without charging over $1000 to replace the entire screen. They say that it is not a widespread issue and the TV is out of warranty, so it falls onto the customer to pay for the repair.
Summary: I purchased this TV in December 2010. It is now May 2012, and we have a broken pixel. The estimate to fix this problem is $1500 USD. There is a hum, which is not that bad. The picture on this TV is amazing - however, you should plan to replace the rear panel after 16-18 months (broken pixels are very common in tv's this large). Samsung has greatly disappointed me beyond my comprehension. I will never buy another product from them ever again.
Summary: I bought this TV in November 2010. The picture on the TV is incredible. There are actually discussion boards on the internet because the picture on this TV looks "too real". The big problem is that I've had is its unreliable. About six months after I bought it the picture stopped working. After turning everything off for a couple minutes and trying again the picture came back. Fast forward a year (so now I have the TV for ~18 months) and the same thing happened.
Summary: I am now on my 5th service call for "no HDMI signal found". First tech said all my cables were bad, set worked with his test box, then worked OK when I used my cables. Was able to fix problem with "reset" a couple of times. Then they replaced the input board and it worked for two months. Same failure, "No HDMI signal". Teck replaced the same board that was replaced before, works fine now. Samsung sells extended warrenties, must buy before the 1 year expires.
Summary: This TV is amazing. I have had it for 7 months now and there is no buzzing! Amazon delivery was great. The picture quality and 3D is unbelievable, I have this TV in a bright room and there is very little glare and the TV is very bright.
Summary: Simply put the tv arrived with a damaged screen. Amazon would not offer a replacement tv of any type. They did not want to work with me to fix the problem. All i can say is with amazon buyer beware.
