Summary: This is a great TV. I mostly watch streaming and DVD but regular TV is fine. The only drawback is the sound which is tinny but that is the problem with most thin screen TVs. Get a sound bar and that problem is solved.
Summary: I ordered the Sony EX645 50" in April 2013 after extensive research in stores and online from November 2012 until I purchased it. With all that was out there, the Sony kept popping up as the one I wanted. I was especially impressed with the dark blacks in the store, along with the overall pictures and it had everything else I was looking for. I purchased it on Amazon for a total of $914.48 including shipping.
Summary: The TV picture is very good and it was not difficult at all to set up. I was very happy with this TV until, after 8 months of ownership, it would not turn on. The story of Sony's handling of the repair through their "customer relations" department is long and painful. The short story is that they have turned me and my wife into consumers that will avoid Sony in all future purchases, not because of their products but because of their customer service.
Summary: It works really great and no problems what so ever. I love the WIFI because I get NexFlix for $8.95 a month and also can get a lot of show on the internet. Hook up was simple and that is coming from a 62 year old.
Summary: I would rate model KDL50EX645 less than 1 star if I could. I purchased the KDL50EX645 on Nov. 23, 2012, Black Friday at a SONY store. I have long wanted a SONY TV and I was delighted to have finally purchased one. I gave away an eight year old, 37" Phillips, flat screen TV that was working perfectly. I just wanted a SONY. While the TV did not have as good a picture as expected, I was willing to live with the picture quality because I got what I thought was a good price.
Summary: The tv would not turn back on after 3 months and Amazon would not let me return the item and Sony's customer service is a joke, it's been 3 weeks and they still have not sent me a replacement tv.
Summary: I've had this TV for 3 months now and find it OK for the price. Here are a few points which I'd like to mention: 1. Lots of apps: The number of apps supported is pretty good but the interface which is common to a lot of them is very primitive and seems like what is probably easy to program on using whatever Sony offers to the developers. Few popular apps have a better interface to them namely YouTube and Netflix.
Summary: This is a very good unit. It arrived as scheduled - a carrier called to make delivery appt. and then again to confirm. It was well packaged. Setup was easy, including connection to wireless internet.
