The UN52A650 doesn't have any updates that include Netflix functionality.
We purchased our TV a few years back and noticed that Netflix has become available on many of these newer TVs. I'm just curious is there is a software update available that might allow us to take advantage of this feature as well. Our TV hasn't connected to the internet previously, and it would be a hassle trying to get an ethernet cord there - which is why we havent connected it previously.
We currently use our Xbox360 to connect to Nexflix but my Mother & Grandfather both are not very comfortible using an Xbox to use the Netflix feature.
