Summary: I've had this 40" set for over two years and have had none of the reported problems. It works fine, has a great picture and has been a joy to use. I have added a sound bar and that makes a lot of difference in the sound quality.
Summary: After a white smudge appeared within the screen, I had second thoughts about the wisdom of the purchase. But my warranty was in effect and Samsung replaced the screen; a satisfactory outcome. As for the set itself. The quality of the picture is excellent. I have found nothing lacking in the 60 hz model. It seems most broadcast signals come into the set at 60 hz anyway, and blu rays play well. The sound is the only thing which could be improved.
Summary: This is ny first HDTV. Set up was simple and it's a great picture. One thing that didn't work is that i couldn't get any sound and only got a grainy black and white picture playing DVDs with my low end Curtis DVD1041 player. Do I need a HDTV compatible DVD player to play simple exercise videos and such?
Summary: I just received my Samsung 37" LCD. Setting up was easy. Directions for programming could have been a little more specific. With so many different sets out there they made many assumptions that some of us novices might not understand. The quality appears good. I have a 60HZ panel frequency. I returned an LG 42" with 120HZ due to size and concerns about quality. It is a small difference, but you can see where 120HZ is a more defined picture.
Summary: Bought this for my mother for Christmas. Replaced an old 200 lb Sony. Unlike my Sharp brand TV, I am having trouble with this Samsung staying in any particular picture mode. Sometimes when in a "wide and fit" mode, I'll change channels, and come back and have to reset the mode. This doesn't happen on the sharp TVs. The manuals are extremely complicated and frustrating for an older person, and sometimes don't make any sense for any age person.
Summary: In 2009, I purchased a 46 inch Samsung 46B650 LCD for my family room and I loved this TV so naturally I got this 40 inch Samsung LCD for the bedroom in 2011. Samsung LED are better but I could not justified the cost difference and I rather put the cost difference in a larger LCD screen size. This 5 series has the great picture quality similar to my 6 series that is 2 years old.
