We bought a Samsung LED TV 46" Series 7000 and, after less than a year, some parts on the right side of the screen start growing darker and darker as time goes by. After over a year, the right one third side of the screen is so noticeably darker than the rest of the screen. You can hardly see any details of the picture that happen to fall on the darkened side.
We tried hard to reach Samsung for warranty and we have always been given a run-around and excuses. It took so long to get the nearest service center, and after finally locating the service center, it took so long to get them to respond. Samsung's service really sucks!
We're going back to Sony. You can't trust this brand... they still have a long way to go in terms of quality!
Please be forewarned and don't waste your money on Samsung products.
