What People Are Saying

Rated 1 out of 5 by from POWER WENT OUT DEAD the TV worked till the warranty ran out. Then it would power on then turn off...it would do this randomly since we owned it but we thought someone accidentally pressed the remote as time went on the power finally went on and off just as fast. Now there is no power....garbage

Rated 4 out of 5 by from Good Video, Lacks analog output I have this TV since 2010 May - I bought this during a Fry's sale for 1000 Dollars. The picture quality is great. It does have AV sync problems and I am used to it, however when friends come to my home - they do notice it. Another major issue is this TV does not have a Analog ouput for Audio and I am unable to connect my Bose speakers to this TV. If you are very particular about having audio connected to a Home theater with only analog in - Dont buy thisTV.

Rated 5 out of 5 by from Great Value for Features I have owned for over a year and am still pleased with the quality, image, and size of the screen. The TV has never given us any problems and has all the hookup we need.

Rated 5 out of 5 by from Great Deal! The picture quality of this TV is great. The Tru Motion works pretty well and the energy saving light sensor adjust the TV perfectly according to the lighting. Overall I think this TV is a great product for the price. You simply can't lose.

Rated 5 out of 5 by from Really good TV, really good deal Our church has now been using this TV as part of our normal Sunday services for more than a month and it has worked/performed very well. The only interface we're using on it is the VGA input (to push computer-based video from our sound booth) and for that use the TV has worked flawlessly. The TV looks very nice in our sanctuary and its matte screen is perfect for avoiding any glare from lights/sunlight. We actually just bought the newer model (55LD520) for the other side of the room and it is working well, too. Got a great deal on the TV (it was on closeout after being discontinued) and it has been well worth every tithed penny.
