Summary: Bought this to replace my Samsung plasma and wish I had purchased another plasma as the picture quality isn't as good. But if you've never had a plasma you will be happy with the picture quality. Sound is very disappointing. Very tinny. I just purchased a Vizio sound bar which has improved the sound. Another short coming in the fact that it only has two HDMI connections and no S Video connector.
Summary: Got this tv in open box condition. Could not find a scratch on it anywhere. Very descent picture. Has a ton of advanced color controls. Someone reviewed the tv and said you could not control the refresh rate and things looked like video. That usually occurs when you over sample or add frames like samsungs motion plus. This tv will playback the refresh rate from the source so movies at 24 frames per second look like movies the way they are intended.
Summary: I needed a new TV after buying my house and this was a great choice. 55" is just the right size, not too big but not too small. The screen is crisp and the HD picture is as expected. Great Buy!
